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

[@markoplixo]

Great work mon!

[@johnnyb8629]

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.

[@D2DNYAC]

OK my friend thanks for watching

[@phillip5397]

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.

[@D2DNYAC]

Okay

[@D2DNYAC]

What link?

[@Randylazz]

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

[@D2DNYAC]

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

Thanks for great video, just wonder that where the compressor capacitor locate?

[@D2DNYAC]

Thank you for stopping by

[@D2DNYAC]

I believe this a 3 ph power unit and this no capacitors needed

[@pdavis4436]

What about the fan spinning opposite direction that’s diagnostic to.

[@D2DNYAC]

Could be yes

[@sergioramirez9025]

How did you run the motor with other capacitor such as the wiring goes? Since you removed both brown wires??

[@D2DNYAC]

Because the run cap is use mostly for starting the motor

[@patricktelfort]

how'd you get it to run in the proper rotation?

[@D2DNYAC]

3 phase motors just switch around any 2 power wire leads

[@HVACRTECH-83]

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

What happens if the condenser coils are cleaned but still you are expiriencing high pressure

[@D2DNYAC]

Condenser fans( check air flow across condenser)or refrigerant charge issues

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.

[@D2DNYAC]

Yes the demand is here, you just have to know how to get started .

[@BillyN31]

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.

[@D2DNYAC]

Got it

[@BillyN31]

@@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!!

[@user-hj5le6lo9w]

Years back the journeymen would call it the “low or no amp lockout”. Thanks for the details on it!

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.

[@boulmo9167]

24:56 how ?

[@D2DNYAC]

Good question my friend

[@D2DNYAC]

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

Not how a lockout board works. Doesn’t look for high amps it looks for low amps.

[@D2DNYAC]

Interesting 🤔! What are you saying?

[@davidwalz2283]

@@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

[@D2DNYAC]

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
