    Following your checklist, I was able to eliminate all possibilities except #6 - failed control board. Sure enough, when I pulled the board out and inspected it closely, one of its tiny components had been deep-fried. Thirty minutes later after a trip to a local supply house, the blower was running normally again. Fixing problems like this can be simple; identifying what needs fixing is where expertise like yours is so valuable. Many, many thanks for sharing!

    SIR - You are God Send Help. THANK YOU A MILLION AND I WILL NEVER FORGET YOU.
    My situation was the Inside Air Handler or Evaporator Blower motor wouldn't turn on, while the outside compressor condensing unit will turn on. I was afraid that the air handler motor /Capacitor / relay would be the culprit and perhaps even the controller board. I have changed the motor / cap and relay on the condensing unit but never messed with the Air Handler Blower or the inside unit and was dreading it. Your Video saved me from no telling what kind of an expensive ride I would have had with those AC repair service surprises. Mine is a 35 year old Goodman unit and probably doesn't have the ECM etc since it is a single speed motor. I watched your video in full and was going to go step by step. I followed Step 7 (the thermostat) first since it was easy and never knew thermostat could cause an issue while allowing the condensing unit to come on. I removed the Battery, measured the voltage was reading 1.334 and was hoping a new BATT would help. Guess what i put a new battery and the Fan handler came on and the AC is working now. Never realized that thermostat showing to be in working shape could cause this. May God Bless you for your Great Service and Once again a Big Thanks to you and you are TRULY GOD SEND HELP.
    One question sir - Is it normal for the condensing unit to come on first and the Air handler fan to turn on after a 25 second delay. I dont think it was like this before. Is this some symptom of some thing coming... Thank You.

    Whew! It was the thermostat batteries. This just happened tonight. I heard the burner ignite and the gas flow but noticed the fan didn’t start a few minutes later like it normally does. I turned off the heat and turned on the fan and nothing. I’m thinking the fan motor is shot or maybe the capacitor. Did a quick YT search and found your video. I never would have thought of the thermostat batteries. The display did not show the BATT indicator. I replaced the batteries and the fan is working. Thank you.

    You got my attention at 8:50 with your yellow magnetic jumper wire. Never seen these anywhere before and I see Amazon has them. I troubleshoot a lot of industrial machinery and with most of the terminal strips there is no way to attach a meter lead and a person only has two hands. I was going to make some of these leads and bought and received some small neodymium magnets. Another thing is why a person should use a bleeder resistor instead of a screwdriver to discharge a capacitor is because some capacitors have an internal fuse and if you use a screwdriver you run the chance of blowing the fuse besides blowing the tip off of your screwdriver. Great job.

    A note on the thermostat face: after I changed my batteries, I still had to jump one of the connections before the face could become functional again. I also tested my cap, it was on the lower end of its capacitance rating, but I wonder if draining it and putting it back did something as well… one of my EE coworkers recommended I try that specifically.
    Anyway, thanks for the awesome video!!

    @da-os3qf 5 หลายเดือนก่อน

    your channel pretty much put me in the position to almost fully diagnose what has gone awry with my 3.5ton carrier heatpump package. sadly i have not isolated the problem as of yet. the original problem: indoor fan blower moves freely with no noise and is seated properly but motor movesonly in a stop go fashion (small movements). compressor comes on, bottom of accumulator and some of the lines frost over (ambient outdoor temp is 107 between Noon and 1700 )since it is an older 42 size system i felt it prudent to start replacing the usual culprits:
    capacitor. hard start kit. defrost board. single pole contactor. replaced blower motor. thermostat good.result: same issue. outdoor fan is fine. condensator coils and ubends look good, unit very clean. wiring clean. no obvious oil deposits anywhere on copper lines, valves, connections.
    what's next? replace fan board? refrigerant charge/leak?

    Thanks for sharing this info. I replaced my blower motor several years ago and it has worked fine until this year. If I put it on fan on constant and it starts it will run for ever until I turn it off. If I leave it on automatic it may or may not start when the compressor runs. I'll check these points you have shown us. I only work on this stuff every few years and I have put this off for months just letting the fan run constantly and wasting a lot of power. Getting too old to crawl around in the attic have had four knee surgeries in the last two years so I have plenty of excuses. LOL!

      If someone who is watching these videos relating to HVACR is actually wanting to increase their knowledge and become an 'expert in the field', these facts represent logical truths. So it is only fitting to elaborate further on the subject by 1) explaining what the readings on the multimeter represent, and 2) differentiating between what the 'rating' and 'value' is in relation to a capacitor.
      'Take a chill pill.' is something someone who is ignorant and lacks understanding would say.

    Also when you buy it new , does it come with new circuit board mounted already or you move old one to new ?

    What about the blower motor reset button? Or does the light switch mounted on the side of the furnace pretty much do the same as a reset button?

    Did you make that bleed resistor or did you buy one ?

    I have a Goodman ECM motor and it sounds like a jet airplane when it starts to crank up and it's very loud on Air Conditioning mode. However normal on Fan only.
    Have you heard of this symptom before?

    Thank you! At the #3, what if I test the blower common and capacitor wire, one is 45ohm, and another is 0ohm?

    Can the motor itself be cleaned and oiled to return to service? Troubleshooting mine...found the thermostat set to "on" which means the fan was running 24hrs...i don't know if dust /heat ruined the bearings or if it can be cleaned and tried again. Im not sure if i can spray electrical cleaner into copper coils of motor...seems thst could cause more damage.

    Do we need to check the vac rating along with microfarad rating while installing a cap to blower ?

    • @YuriSoul2222
      @YuriSoul2222 2 ปีที่แล้ว

      Yes, make sure it is about 1.5x the AC Voltage that powers the motor. For example, if your motor is running with 240 VAC, then you want a capacitor that has a rating of 370 VAC or higher. And also make sure the microfarad value is the same as the old cap you're replacing.

    Insulation tester is a good tool aswell to check the windings to ground

    I woke up this morning to blower not working. I have it working again now, but I'm sure it's going to fail again. I seemed to have power in all the places I could test. I could not find a capacitor though. There's a 5 amp fuse on the panel. I checked that fuse and it was fine, but when I reseated it and checked again it started working. I had reset the breakers a time or two before this while testing. I'm not sure what pulling the fuse that the breakers didn't do, if anything?

    Is it normal for the condensing unit to come on first and the Air handler fan to turn on after a 25 second delay. I don't think it was like this before. Is this some symptom of some thing coming... I am going to may be lube the fan blower if there is a lubing option available as a preventive maintenance. Thank You.

    Hello. Our American Standard HVAC fan froze this month for a few days here in Virginia. Our HVAC guy came out and said it was fine, but yesterday I turned it on and the fan won't operate at all. He said to turn it from regular heat to emergency heat, but that is expensive and a temporary solution. I tried turning off the fuse for thirty minutes. That brought back the flashing light on the thermostat displaying the auxiliary heat option, but still didn't fix the fan issue. In addition, if I run it on regular heat, the temperature on the left side starts to drop below the temperature on the right side. Do you have any recommendations? At this point, I guess I need to call a new HVAC guy for this situation. Thank you.

    One question, I did the jumper of the thermostat wires coming into the motherboard the blower instantly came on does that mean that my thermostat or the wiring on my thermostat is not working properly?

    What does a very low ohm reading (0.06) indicate on one of the capacitor leads?

  • @mbflyin

    What about Dual Capacitor systems without a cap on the blower motor? My blower seems to work periodically, and it doesn't have a capacitor. It has 2 cable harnesses that plug in; one with C, L, G, N, and the other with 1 2 3 4 5. I checked and the harness is getting steady 123v, but when I plug it into the motor it sparks/pops, so what could be causing that? The motor has a removable butt plate with what I assume is a thermistor. A second cable with a 3 prong harness plugs into the motor on the inside.

    Got a Top-10 ECM blower motor problem vid by chance?
    So my package RTU's CFM ECM blower motor's frequently speeding up/slowing down/speeding up/slowing down and turning off completely only to start back up; all during a single cooling cycle. It's acting up more so in the late afternoon and evening hours. Does the same thing in fan only mode, too. Takes several minutes for the motor to come on at times, even in fan only... kinda weird.
    Clues?
    Great channel, BTW... thanks!
