The brilliant engineers are about to break the customers. It is not ok to reengineer parts that use to last 20 years until they cost 4 times as much and fail 4 times as often. Curtis, you are a good man. Thank you for believing in and always taking the high road
What happens when government creates monopolies that own near everything.
Stuff today is made to fail. They know what breaks. Go look up any model number of a product and you will find "common" issues. Its not like we forgot how to make products last
The public at-large needs a dependable and completely unbiased location they can go to to obtain the stats on such things as breakdowns and premature failures, premature being anything that fails before the ten year mark. Based on systems and applications. For instance it should be a requirement for any havac system to last atleast ten years without a single system failure, things like lawnmowers should be a minimum of five and so on. This should be mandated for the product to be allowed to go to market. And systemic failures should be forced to be recalled or warrintied for a period of no less than five years from the last failure prior to the original mandated maintenance free period. And warrintied means no mater how many times it has changed Hans. The public needs this kind of support from the government and this location to obtain this info with out having to be an engineer to retrieve it ot locate it. So the public can have the final informed say in who makes it to the next year in business. If a politican wants a good platform addition for a run this would make one hell of good start.
The problem with the HVAC business is that the systems are chosen by the builder on the basis of the absolute lowest possible cost. So they make the stuff with next to no margins, and make it all back on the back-end. The component guys are happy to supply replacements to the aftermarket at 10x the price they sell to the OEM, and the OEM just cares if most of them make it through the warranty period. These motors that sell for $800 as replacement parts likely only cost the OEM $50-100. So they really don't care if a few of them need to be replaced.
These days, an ECM motor isn't significantly more expensive to make than a PSC motor. The difference in replacement costs is mainly because there is less competition. Especially for variable speed motors where they need to communicate with the control board.
boy you got that right
Seeing all the problems with newer systems is why I keep my 20 year old system lol old school
Mines 32 years old now I replaced the fan motor and several capacitors etc
Mine is a Carrier weather maker. It is 31 years old. Yes, I have replaced every part in the furnace except the heat exchangers at least once, myself. This summer my R22 condenser and coil developed a leak. Had to get a shot of "R22 Golden Juice" three times. ( What they charge, thanks to our wonderful government, is absolutely ridiculous. The scientists determined many years ago that the ozone layer varies year to year and it always has, but they are gonna ride that cash cow into the sunset on our tax dollars)
Time for a new unit. I'm doing it myself, with Stabrite 8. I've plumbed many homes with copper, read up on Stabrite, and that's how I'm going. I'm good at sheet metal, electricity, and gas. I'll have my neighbor who is in HVAC check my work and the charge.
@@earlestes8649What make is yours?
As I said in the Knights livestream, I will continue to watch you change out motors time and time again. You are the PRO at it, keep your customers happy. Good job brother
Thanks
Nice drive in a nice town! Didn’t think there would be palm trees in South Georgia lol, there’s way too many here in Central Florida. It’s always cool when going to the supply house for parts during the day wondering who you’re gonna run into and what conversations may spark up. At the end of the day, we’re all brothers in the trade doing our best to get the job done. Great video man keep it up!!
Thanks 👍
Great job Curtis, I just got my epa certification so this is helping me alot. Thank you so much.
You seem to be very good at troubleshooting problems that others can't figure out. Also a perfect guy in general for taking care of neglected dogs in another video, so I would hire you but I am in MA. Your videos are very informative. Lots to learn, though I wouldn't take on an A/C repair. Keep up the great ethical work!
Really liked this video
Thanks!
Thanks to you
I lived in Albany for 25 years and moved to North Georgia in 2002. Enjoyed the ride down Slappey and Olgethorpe. Keep 'em cool.
Glad you liked it
you could get some two-inch square peel and stick pins with metal washers to hold up insulation in units as long as metal is fairly clean
thanks for the ride-along! too bad we didn't get to see a train Lol
sounds like you might want to drop Ruud installs like hot potato if they fail constantly and they can't keep parts in stock... how rude!
I often wonder why don't you just magic marker and mark the fan assembly where the wires were ( direction and place ) - I guess you can just remember since you do it all the time - another great job Curtis thank you for the video.
Great video,Curtis! Great work!
Thanks!
Liked the drive and music. Regards from UK.
Glad you liked it
Nice work Curtis.
Thanks!
Failing within a few years of its install date? How Ruud! 🤪
I feel your pain on that whole stripped-screw thing. I just bought brand-new headlamp assemblies for my Jeep, I took the included no-name-brand bulbs with the crappy beam pattern and replaced them with used Sylvania halogens. One of the used bulbs failed, so I went to replace it, and discovered two of the four holes that the trim ring screws thread into are good for two uses and that's it - stripped-out already. And I used a hand screwdriver the whole time. Such a waste.
Loved seeing the drive through Albany! Reminds me of visiting family in the Florida panhandle, most of those smallish Southern towns still retain a quiet humble appearance that is quite charming. Yes, Albany is massive when compared to my little Connecticut town of 3,400, but it doesn't _feel_ like a town of 67,000.
It’s been that way for years…since about 6 months after their introduction….they first used a rubber type coating in the module which they determined was absorbing moisture…changed it to some sort of varnish material but the problems persisted
The biggest issue constant torque motors are failing due to duct work ( high static pressure). The motor will increase speed to overcome restricted duct systems resulting in higher back EMF from the motor to electronics ( inverter)
Fingers crossed it keeps going, my 2013 era Lennox still has its original ECM motor
Mine is from 2010 and still going 😃. Lennox makes their own motors.
@@michaeldarrow6021 no they don't.
It's only 11 years old, the FAN BELT on the blower in my dad's furnace installed in 1948 lasted 35 years. The heat exchanger was cast iron, and it had a simple pilot light kept on by a thermocouple. It never failed. It was replaced by my sister to get central air conditioning. Back when my Dad built his house, nobody ever thought that the furnace in a house would ever need to be replaced. When I hear people calling a 10 year old unit OLD, it makes me want to puke. There is no longer ANYTHING made to last.
I just changed one in a goodman front return. The installer left the installation manual behind the coil, was in a plastic bag it comes with. covering half the coil 😂. They’re so sensitive to lack of air flow. They will typically die within the first 5-8 yrs typically regardless. Thanks for the video, as always.
There's this house inspector here on YT. I think he works near the Nashville area in TN. In one of his videos, he mentioned that gas furnace installers, where leaving the manual and tech sheet, inside of the unit next to where the flames and burners are. And they had some fires start because of it.
@@KenKen-ui4ny Oh damn that company’s insurance is definitely dropping them 😂
I would always use non ecm motor (after warranty period).
So the funny thing with me is I was in the Hvac program back in 21 and My blower motor went out and that same week I was actually working on the squirrel cage and removing the motor for that portion of the program and of course I had no choice but to call tech out and I had to pay $350 just for him to replace the blower motor because it was under warranty. My OEM one was a module one but he said he didn’t didn’t have one like the one I had so he used a non-module motor and at first I was like no I really like the module because it’s pops off and they cost about 20 bucks but seems like they fell a lot easier than the non-module so I lucked out.
This a big reason why I don’t change out my 38 year old ac and furnace. Original motors on everything. I do however change capacitors and contactors every three years regardless along with cleaning the condenser and doing a carbon monoxide check several times a year during heating season.
Yeah but what about the $20 a month more in electric usage. Could have bought a new ac with the money you wasted with old ac.
@@markcotter2355
I dont think your math is adding up. Lets say it is $20 bucks difference. In a year that is 240 bucks. In 20 Years that is about 4800 bucks. Prices of new HVAC unit today easily can be in the 6000-9000 plus range depending where you live. Assume you want a High efficiency model to get that $20 bucks.. You be paying on the higher end.
Lets say middle ground of 7000. It would take almost 30 Years to pay it off.
I'm just having a 36 year old American Standard HV and Ac system replaced. The system was very well maintained for most of its life. To think that the quality of todays ECM motor would only last for 3 to 4 years is criminal. Thank you for exposing this corporate engineering planned obsolescence failure.
Those ECM motors need surge protectors. Anything with computer chips is highly susceptible to power line spikes and hiccups. There is an optional surge protector available for the X13 motors. Plugs in between the motor and wiring harness. I think there is a TH-cam video on it.
The new stuff needs a UPS, not just a surge protector, IMHO. At least where I live it does. Those ECM motors are supposed to be more efficient than the old reliable PSC motors. They cost about 4 times as much as a simple PSC motor, fail 4 times as fast, and have become impossible to find, so how is that
More efficient?
You need to get a 1/16 & 1/8 hex shank drill bits. Pop it into impact driver, hole drill then you don't break your back trying get screw to go in.
At one time, you could replace the part in the control bell on the end of an ECM motor for about $5.00. Then, the manufacturer started filling the entire circuit board area with resin, so people would be deterred from replacing the part that failed the most. Instant motor sales increase.
That's why right to repair act is required asap. Those practices must fall under criminal law because its just malicious intention. Manufactures should be required to legally proof that there the safety benefits overweight the economical reasons (which they mostly can't).
What was wrong with using a PSC motor? What happened to " If it ain't broke, don't fix it? "
@@vincentlaw82You do know that the scariest thing in the world is someone coming to your front door and saying " We're from the government, and we're here to help you" right?
Which part was it that failed? Please don't tell me it was a PRC made Capacitor?
@@JamesAgans Uh, every single electronics component there is probably made in China, Taiwan, or another Asian country. For the most part, electronics aren't made in the US anymore. There is nothing wrong with parts from China, they make better quality stuff than most US factories. The problem is the clowns who design this stuff (in the US) specifying poor-quality, underrated parts from questionable suppliers to save a few cents.
Hey Curtis how you doing man? I watch your videos all the time. Back in the day I did HVAC and went to school for it, my school text is in storage and it was easier to simply buy another used one which I now keep by my chair so when you're mentioning certain topics I can look it up again. Either way, I was watching one of your older videos compressor swap everything that could go wrong did approximately 3 months ago. I know you have a really cool umbrella which by the way I would like to know where you got it. I try and slow your video down to see the actual umbrella name and information but it usually flashes too quickly. The reason I'm contacting you today is to see if you would consider for yourself, a 10x10 easy up rain cover. I noticed when you're out there doing your jobs your equipment is spread around and exposed to the weather. The next time you do a 4-hour out in the rain job you could set up a 10x10 easy up cover which is just that they're designed to go up easy by a single person. Then nothing gets wet you could take your time you can hang LED lights up in the folding rafters you know the support structure complete work area and when you're done you put all your tools back in your truck like you normally do and then fold that thing down and throw it in the back of the truck and away you go. I know it sounds like a lot but at your age no offense, why not work in luxury? You are your own boss you make the decisions. Peace out be safe keep up the good work Love your videos
Hey Curtis you want to check out something cool? Look online for top secret drum corps. Wow these guys are phenomenal. Precision perfection personified a kid you not you will enjoy it... When you're not working of course 😁
I’ve noticed quality issues in various components which rolled off the factory floor from 2020-2022. Could be pandemic built stuff causing issues.
When I moved I decided I wanted a new HVAC system installed. Having had a great experience with a Trane system at my older place I decided on the same at my new place. Apparently I got one of the last of the great Trane systems. A friend told me he stopped selling them due to leakage issues requiring multiple service calls on newer systems.
Sadly everything is made by the same groups. You really do not have options besides colors or looks. Its an illusion of choice.
This sounds a lot like my old refrigerator which was an Amana, back when they were actually made in Amana (Iowa). Had it for 25 years-it was the most quiet and carefree fridge I'd ever had. My wife insisted that we needed a stainless fridge so I grudgingly traded it in on something flashier with a big brand nameplate on it. One of the worst mistakes I ever made. I wish I had my old fridge back.
Yes totally agree with you on this, they are becoming as bad as the imported caps...btw, looks like Genteq updated the cooling fins on the back of the module where the IGBTs are...maybe they can take more load now and last longer for those higher statics.
Nonchalant, even keel...no fuss Curtis. Clear, consice, measured. Keep it up man.
Thanks! Will do!
PSC motors often last decades. Guess it''s time to put more ECM motors on the truck if these failures are more prevalent. Thanks for the videos!
I have replaced ECM motors with PSC motors, but you have to install relays for heat and cool speeds. Much cheaper and more reliable. Under warranty of course you put OEM back in.
With variable gas valves it’s not going to be possible at some point
I think it's called "planned obsolescence". Run a few years and then fall apart. Lots of lawsuits going on, especially when it comes to appliances. Keep the old stuff folks.
well done Curtis 👍 Au
Curtis. Love your channel, but please use trigger control when reinstalling the screws. It sucks working on a unit that all the screw holes are stripped out
I like your road trip music
I think I'd include a surge protector with every new install.
Surge protectors have a limited lifespan. The diodes in them break down on repeated hits.
Can you give us a lesson on how to retrofit standard motors into a system that had ECM motors? Thanks
7:20 those HVAC bicep gains go crazy. My arms look shredded after only doing this for 6 months
Tks for explaining the wire loop. Interesting
It's called a drip loop for good reason. Electricity 101
22:58. Great tip! 👍
Another fine job. Hard to believe that thing is only 4 years old. The copyright thing is ridiculous. If they would pay ASCAP a few bucks, it would not be an issue.
That drive through town looked like a ghost down compared to NorCal traffic.
Small town
We always include a surge protector on every unit that we install and highly recommend it when repairing systems with ecm motors and the ones we have found bad have been 10 to fifteen years old and the ones that failed in a few year's are set to higher speed than system needs to overcome bad ductwork and customer not maintaining uni or changing filters causing higher negative pressure in return pulling moisture into motors .can't remember last time I had to replace motor under warranty
You worked on this one not long ago, I remember the Trans-Am in the driveway.
Same here....
The motor manufacturers need to step up the robustness of the components in the modules. It’s pretty plain that the mosfet or whatever they have doing the motor speed control is underrated since they all seem to fail regularly. I would like to delve into one and see just what they are using and how it could be rated for better longevity. I know it’s all about money 😅 and the motor prices show it lol Good repair though! I know it’s almost a regular call these days
I can save you the trouble of tearing it down: they use the cheapest, most underrated components that they can get away with and still get through the warranty period. That's why these fail, they have virtually no margin on any of the components. A good surge protector / line filter device can definitely help them last longer, but fundamentally these are just extremely cheap electronics. I seriously doubt that whole control module costs more than $20 to make.
The other problem is that these are fairly complex electronics that are designed by some of the least competent engineers in the electronics industry. After all, would you rather work on motor drives for some cool robotics company, or an HVAC sub-tier supplier who barely pays anything and doesn't want to spend any money on anything?
@@gor312more than likely $20 or less to build the module considering parts cost and availability which is most likely backordered lol
I’ve had to replace ECM blower motors on a 6 year old Carrier HP and a 4 year old Rheem HP as well, they’re not built to last for sure 😂
Ive had to have 2 Motors with ECM replaced on my Rheem since new at 2000. Both failed during Air conditioning season not heating season. Last one was WAY stupid expensive.
$1200 + ..?
@@gingyberrie I got off for a little under 800$. STILL WAY TOO MUCH FOR A ELECTRIC MOTOR WITH AN ECM
Rheem used to be a really good unit. Today total junk. I replaced a motor and a coil in the first 4 years.
Rheem is not the only one. They all have problems after a few years. It is a shame nothing is made like it used to be
I have to replace a ECM motor for a Carrier infinity system, price for the motor is almost $1300 😂
Not being sarcastic at all, I enjoyed the POV car ride.
Fun electrical lingo - it is called a " Drip Line "
I’ll bet that ecm took an electrical surge from the utility. A $70 Intermatic AG3000 surge suppressor on the wall disconnect is a necessity today. Thats all we use. One on the condenser and one on the furnace if it is a split system.
ECM motors are sensitive to dirty power. Systems using ECM and (especially) Inverter systems e.g. ductless splits need power conditioners to keep spikes and transients out of sensitive circuit boards
I put a York package unit in and within 6 years all the insulation had fallen off inside
Downtown Albany is nice….very little traffic….unlike Austin, TX.
Could possibly prevent issues with controls like that with surge protection. Maybe try that on the new installed units.
I've done two X13's this week. $800.00 a pop. When mine goes out it's being replaced with a PSC.
This is funny cause mine went out and it's just 4 years old. New build in 2020 and the capacitor went out
i wonder if the static pressures are causing premature failures with constant torque/variable speed ibm’s
99% of the time that's what is killing these ECM blower motors.
That's the manufacturers favorite thing to say as it deflects the blame from them. The real problem is that the motor modules use the least expensive transistor module possible and in cases where the static pressures are high, the transistor module is driven to its upper limit where it will always fail. If the manufacturer spent just a few cents more per motor and installed a module with slightly higher ratings, they would never fail, but we can't have parts that never fail any more can we? How dare we make something reliable any more that might take away pennies in profit from a major manufacturer!
@oddo710 that's the cause high static pressure I'm not the manufacturer I'm a well trained tec. We have a very small percentage of bad ecm motors on our installs but we size things correctly as possible. 7 out of 10 systems don't have enough return air so if possible we correct that when we do our installation.
7:12 made me a little anxious lol reminded me of the time I was doing something similar for the same reason on a horizontal split but my dumbass sent a self tapper right into my finger. Don’t judge me
I was just thinking the same thing; Some fast curing super glue work or you can use a couple of metal strips and sandwich the insulation between driving the screws from the top of the unit.
Well, you'll just get labor outta this one, Curtis 😑. In a few more years, you'll get to sell the motor too!🤣
Those x13 motors are real finicky. They hate power blips and are a constant issue especially in the south. Flex and evergreen motors are a life saver and great economic after market motor to replace with if there's no warranty.
It's sad seeing all those businesses closed up
When your impact in those screws in you hear clack clack clack clack clack clack clack clack and then strip it needs to be klaque stop. Just a little creative criticism I love your channel bro
it makes you wonder if it's really worth the expense of these more efficient motors if they have 1/4 of the longevity of regular PSC motors. I'm starting to see this with every so-called more efficient appliance these days. They need to calculate and compare the efficiency within the products lifespan which of course they neglect to do. when these new variable speed motors get too much restriction they either burn out the electronics or thermistor. the old PSC motor will just run slower until the restriction is fixed. planned obsolescence whether they admit it or not.
*obama policies …
Thank you. I’ve been saying that for years now.
Lack of competition. 50 year old Whirlpool dryer was a wedding gift-matched with washing machine. On washer #4 but that gas dryer keeps on going. From Benton Harbor, Michigan. At that time, Whirlpool also made Kenmore for Sears. Harvest Gold and the enamel has had so much clothing pass over it, the finish is worn through.
People say this all the time. I have a full ECM motor in my furnace and its over 10 years old. And before that, two other homes I lived in had 10 plus years for their ECM motors.
Do the job right the first time and make sure static is right where it should be.
@@sprockkets That would be 0.6" ?
U do great work! But what has happened to Reheem products over that last several years.
A dirty filter or blocked aiflow will make the ECM motor fail, always check for these conditions when you have a failed ECM motor.
I have to take a pic of those ecm motor wires every motor swap
Rheem /ruud have been good about warranty
Great video and tunes, was that a scrap piece of tin you used to hold up that loose insulation and did you put a dab of pookie on the screws you put in from the top to seal out any rain etc?
Will you please start using your service valve wrench on fan and blower motor set screws? Crescent wrenches drive me crazy😂
I tell you one thing when my motor goes out I'm ripping it all out and putting a PSC motor in it. the hell with efficiency 12:12
Saw a guy here on YT fix one of those ECM motors. He replaced a Thermistor on the board that burned up.
These you can't do that as the whole module is potted as you see in the video right after he removed it. I've spent the time to dig it all out and try to repair the X13 modules and it doesn't work like the old variable modules. The one I got to power back up had lost its program so still a no go
👍
This is one reason why I choose to remain a commercial contractor.
Isn’t this the system where the tree fell on the power lines and shorted out a lot of the lines? If so, maybe that was the reason for the premature failure of the blower motor?
Sad that early motor replacement is so common these days. The old DC brushed single phase 1/2hp motors by GE would last a lifetime on a set of elevator doors with 10million runs. Baldor has been the replacements, and were decent until ABB took over. ABB had great products until they stopped manufacturing in Sweden, and started in Bulgaria and soucing relay coils from china
Just out of curiosity. What were your static pressures at install? High static can cause the ECM's to fail sooner.
What are the best and worst brands for reliability and parts availability?
The song you used sounds like duran duran coming undone
I say you should feel free to just swap the ECM. Now really, I never go through all that testing when I know full well that the ECM is what is wrong with it. I've never seen a bad motor, just ECM's. Your supplier just doesn't stock them and that's your only way to get one. Which is a big problem just like the Ecm going bad to start with. Once the door's off you can swap ECM in under 2 minutes. I know you know this and have to keep up appearances.
I'm glad I can get the Ecm only, but they cost almost as much as an after market Ecm motor. Last one wasn't under warranty and cost me 290, which is still 50% of whole OEM motor. These supposed highly effecient motors that cost 3x of a reg. motor and break down 3x as much. Well the ecm does.
@@jeffreywhitlatch1409 it’s typically what I try to do but sometimes it’s difficult to get an correct ecm module since they are programmed for each system, they may look alike but are not the same.
@@davidb2438 unfortunate to have supplier nearby that has them, and can program them. At least for a Ruud anyway. But I have in the past gone there and gotten modules for different brands and just told him they were for a Ruud and it worked fine.
Buddy those motors are crap in my opinion. I get replacing one with the same x13 or whatever if it’s under warranty but I’m so fed up with them I’ve just installed a relay and put a regular motor in especially when I replaced the motor on the same unit twice in two years and by the second time it was no longer under warranty
If ohms were all the same on that motor would it be good and the module be bad?
Yes
When ohming a motor what numbers are you looking for? Also, how do you know what to look for?
Really just looking for the same numbers, and nothing to ground
I had a Genteq ECM 2.3 1HP motor go out. I checked the ohms and it was something like 1.6, 4.6, 4.8. Nothing to ground. That told me there was a problem with the winding wires. Also the motor had noticeable resistance when I tried to spin it by hand. I disassembled the motor and was able to find the wire with burnt insulation that was shorting to another wire. After I isolated the wire, the ohms were 5.6, 5.6, 5.6. I knew I found the problem. I used epoxy to insulate the wire. I reassembled the motor and it worked. It also spun more freely than before. Ohming the motor is a good way to check the windings. Also, if you spin it and feel resistance this could also be the windings. I'm not sure how to test the endbell unit but fortunately the endbell was still good.
Insulation always comes loose.
Oh, maybe you should look at fixing the ECM, might be lucrative if you could figure out how to do that.
Nice background music
Too high of return static pressure is the culprit of many constant velocity motors demise
What is so efficient about having newer systems that break all the time? Probably about as often as a 1950s car without a dip feed engine.
I tried to google it. I give up. What's a dip feed engine?
Every since they started making them in Mexico. They never been the same.
When Trump said they're not sending their best, he was referring to motors
There we go again; foreign plants are set up by American companies so most of the work is automated. We should make all units and parts in the USA. So quityabellyaching! lol
I'm not in any way educated on how it all works but I have to ask the question, is there no way to bypass/hotwire/override what I'm assuming is just a tiny board with a couple chips on it to drive the motor? if your replacing high tech with low tech at this point.......can't you just bypass the control altogether and if necessary add some type of resistance to get the desired voltage/speed? Like I said I probably have no clue really what I'm talking about but my basic question I feel is valid enough...can the ecm part be bypassed? seems like it would save a lot of money and trouble....but I guess liability would say "no" anyway.......
I work for small company that makes ' made to order ' electric motors. Maybe they need to make replacement motors for these units.
They would probably be too expensive.
Do you recommend surge protection for X-13 and ECM motors? Or are these landlords that don't want to spend any more than they have to?
Not a bad idea
@@adampajcz8719 surge protection and proper static pressures are the two drivers that kill them
good video curtis what do you mean they have to program the moter
Same motor fits in multiple different systems. Just needs to be programmed
Are dirty filters a contributing factor?
Dirty filters, undersized ducts, incorrect speed settings, etc. Anything that causes high static pressure will kill them.
@@TofuInc what do you consider high static pressure before and after air handler? 0.6 inches ?
@@philiph1234 .6 is generally a good number. You really have to look at the equipment. Some equipment is rated for up to .8, I know a lot of furnaces are only rated for .5. Your measuring static pressure across the equipment, that is the pressure that the blower sees and that is what determines the airflow.
Did you ever think of using any anti-seize on the shaft makes it easier next time
ECM motors are great, but they do seem to fail significantly faster than PSC motors
Assuming you had spay glue , why didn’t you use it to stick that insulation to the metal ?? Instead of the screws with the piece of metal ??
Ecm are great in concept, but their fragility is so bad. Out of warranty cost is so much more than most customers want to pay.
Yes. very efficient when they work.. surge overload problem's in module.
I have to replace a ECM motor for a Carrier infinity system, price of the motor is almost $1300, out of warranty and customers have a home warranty 😂
These systems come with 10 year part warranties, so if the manufacturers want to keep eating the costs, so be it. That alone should be reason enough to make them properly in the first place.
They make it all up with absurd replacement out of warranty costs though.
What does ECM stand for at this point?
Every crappy motor?
Those ECM motors always failed. Use to constantly replace those.
Those ECM motors are a pain. They are too susceptible to power fluctuations. It's important to have surge protectors on them. I would guess that most people don't have surge protectors, especially on their outdoor units.
When shove comes to push ,considering the cost of these motors customers op for the psc motors even if they'er still under warranty
