You my friend would make a good teacher at any school, it seems to me that you love what you do and that makes the difference. Worked on RTUs many years ago and now only doing residential, keep up the good work! We wll be watching you here in walnut, ca
That unit was made on the 4th week of 2001. Carrier units have unique serial numbers, first 2 number are the week of the year, last 2 numbers the year it was made in. Great video brother!
This video is awesome, it's an actual no cool call. Seems other's videos were staged, planned, and set-up. That's fine there is education value in that. This video can be helpful to techs bc it's real world, and takes us through the adventure of trouble shooting
Those unit have a known problem with the condensers , the coils are stacked one stage on top of second stage and the top coil always gets recirculated condenser air so one stage always runs higher head than the other. Usually fix that issue with a old style hail guard but you can't get those anymore so many fabricate their own to keep them running. more often than not you find these with all the high pressure switches disconnected. They make a 25 ton version with semi hermetics and those slab coils are thick and get plugged so thoroughly you can't clean them with out the fire hose treatment. basically you want to get rid of these as they are money pits, sometimes the belt break and grab all the capillaries and rip them out of the evaporator, I have seen them eat so many compressors the condensers get clogged with braze balls and shellac from burnt motor windings etc etc.
It’s a little different with a building as such with vavs but In general I do utilize google maps. Pin the location downstairs, then walk to the roof and return back to your pin location. This works well with warehouse exhaust fans as well.
Great video D2D! Wanted to ask if there is a big need for HVAC techs/installers in NYC. I’m in school in NJ and looking for employment outlook around here.
Boa noite tira uma dúvida as placas dos equipamentos centrais normalmente sao modelos padrões. Ou tem diferença.? Sou Brasil acompanho seus videos. Parabéns
No building automation? That's how you find out rite away which one is down. I'd be suprised if a setup like that had no automation,if it doesn't than yeah that sucks but you're rite about checking for no condensate, good place to start for sure
Would have been nice to see its approach, once everything else was made good. Approach can give a good indication of proper charge when there's no liquid line port.
@@D2DNYAC I had both boards go bad the other day. Checked my amps and both stages, both good. Jumped the pressure switches out after verifying pressures were good. Still cut out on lockout. All you have to do is remove the shared common (x terminal) and it will bypass the board and keep the pressure switches in service. Thanks for your videos!!
Here’s how, the capacitor is connected to the start windings of motor, which is responsible for starting the motor and determines the rotation. Hence with a bad capacitor most often motor will not start or may start and runs in wrong direction. By using your hands you can almost replace the start windings
@@D2DNYAC if the compressor does not pull more that .5 amps then the lockout board will disable the system until a power cycle resets it. wants you to find the cause, ie LP or HP etc. you will know you are on lockout if you have voltage to the x terminal
Perhaps you arev right my friend! However 🤔 I will have to test this theory 💡before I can accept it ! I will also do a video as well if possible stay turned
@@D2DNYAC I know your Jamaica buddy lives in Irvine used to live in Florida he always called you for help I recognize your voice from Mr Robert is this ricky?

Great training, i like the way you explain .
Thanks 😊
I found gold!!! This video is so helpful and will definately help my grandson in his new hvac job! Thank you so much!!!

This was a great diagnostic video
One of the best videos on TH-cam
Thanks
Great work mon!
Great video!
biggg up! great diagnosis, great walk through!

Great video D2D! Wanted to ask if there is a big need for HVAC techs/installers in NYC. I’m in school in NJ and looking for employment outlook around here.
Yes the demand is here, you just have to know how to get started .
I enjoyed the walk through on this service call.
I’m in the market for a clamp meter would you recommend the Amorobe meter for a HVAC/R
Amprobe is all I use now, I have used several other in the past, however Amprobe meters is the best in my experience as an HVAC contractor
Just subd, this was a really good class sir
Thank you for stopping by
Thanks for the video =)

Thanks for great video, just wonder that where the compressor capacitor locate?
Thank you for stopping by
I believe this a 3 ph power unit and this no capacitors needed
"...is that factory ?"😂😂😂
That should be put on a T-shirt for your company!
😂😂
🤔😂
How did you run the motor with other capacitor such as the wiring goes? Since you removed both brown wires??
Because the run cap is use mostly for starting the motor
Thanks
Thank you for watching
Great service call fam ! send mi ur link so that i can learn.I am in school at the moment studying hvac 😊
What link?
Hey my friend are you from Jamaica? My family is from Jamaica as well

What about the fan spinning opposite direction that’s diagnostic to.
Could be yes
how'd you get it to run in the proper rotation?
3 phase motors just switch around any 2 power wire leads
Would have been nice to see its approach, once everything else was made good. Approach can give a good indication of proper charge when there's no liquid line port.
Thank you for stopping by
What happens if the condenser coils are cleaned but still you are expiriencing high pressure
Condenser fans( check air flow across condenser)or refrigerant charge issues
what model of unit was this ?
😕 🤷
Those CLO boards have to read a minimum of 2.5 amps within 1 second of startup. It doesn’t lock out with high amps.
Got it
@@D2DNYAC I had both boards go bad the other day. Checked my amps and both stages, both good. Jumped the pressure switches out after verifying pressures were good. Still cut out on lockout.

Years back the journeymen would call it the “low or no amp lockout”. Thanks for the details on it!
Hi pls how to charge 407 package unit reheem
Are you a technician?
Need to be careful your touching live voltage wires and stuck your finger in the Contactor while it was pulled in

No
Are you a jamaican

24:56 how ?

Hence with a bad capacitor most often motor will not start or may start and runs in wrong direction. By using your hands you can almost replace the start windings
@@D2DNYAC ohhh lol ok. make way more sense the way u explain it
Not how a lockout board works. Doesn’t look for high amps it looks for low amps.
Interesting 🤔! What are you saying?
@@D2DNYAC if the compressor does not pull more that .5 amps then the lockout board will disable the system until a power cycle resets it. wants you to find the cause, ie LP or HP etc. you will know you are on lockout if you have voltage to the x terminal
Perhaps you arev right my friend! However 🤔 I will have to test this theory 💡before I can accept it ! I will also do a video as well if possible stay turned
HP wouldn’t cause low amps

I know who you are. Your ricky?
Perhaps
@@D2DNYAC I know your Jamaica buddy lives in Irvine used to live in Florida he always called you for help I recognize your voice from Mr Robert is this ricky?
@@D2DNYAC regardless your the man I'm your fan. Ty for the knowledge
i have zero faith in myself knowing how to diagnose anything electrical
Just keep watching my videos then😂 it will come to you
What, slow down
😂😂
It’s a Sucker
Great video!!
