      [Webinar] Samurai's Sealed System Sleuthing Secrets - 10/30/2017 @7PM ET   10/19/2017

      Having laid some theoretical groundwork in the last webinar, we're going to focus on practical considerations in this one. That means quick n’ dirty techniques for diagnosing sealed system problem using strategically chosen and skillfully interpreted temperature measurements.  Review homework from the first session on 10-2-2017. Home refrigerator practical design and operating rules-of-thumb useful for troubleshooting Practical application exercises Troubleshooting scenario exercise Techniques for making system temperature measurements for determining superheat and subcooling Sealed system diagnosis homework assignment (to be reviewed in the next webinar in this series) If you attended the first webinar in this series, this is your payday! We’re going to apply that keen, penetrating insight you now possess into money- and time-saving shortcuts you can use to diagnose real-world refrigeration systems on service calls.

YORK H2RC042S06B condenser unit

Recommended Posts

rolandvz71

OK I am by fair a A/C tech but I do understand voltage to a certain point.

 

Problem:

Outside contactor energizes and nothing is happening....evaporator fan is running inside but no cold air

 

Checked Compressor and it OHMs out good

Also checked the fan and it too checks out good!

 

Checked voltage @ the main panel 120v to GND (L1 and L2) and 240v across (L1 to L2)---good!

 

Now I followed this vid   

and here is what I get.....

 

w/the contactor energized (inside fan running) w/24V @ the coil --- voltage readings @ L1 & L2 @ the bottom of contactor 120v to GND but phase to phase I get 0v. @ the top of the energized contactor  I get 120v to ground, but phase to phase I get 0v. I should be getting 240v on top and bottom of a energized contactor.... right?? The only hmmm I hear is the contactor....no motor trying to start--- nothing!

 

So I think I have a problem w/my FLUKE meter....Soo I check the voltage @ the panel--- 120v to ground (L1 and L2) and 220v phase to phase (L1 to L2).

 

Now get this.....when I shutdown the system down OFF @ the thermostat the contactor DE-energizes I get 120v on one of the incoming lines and 0v on the other incoming line.....what the heck is up!?!

 

Is there something in the evaporator unit I am missing??

 

1st thing I thought it was was a bad capacitor just because it seemed to show all the signs of a bad cap ...its happened before so I took it upon myself to replace it and I still get nothing....

 

Its getting hotter in SE Texas need some guidance! 

 

Thx all~~!

What is the voltage reading inside the condenser disconnect panel?

Probably a bad disconnect breaker.

It was the breaker outside that feeds the unit...getting 240V incoming and w/breaker closed getting 120V. Replaced breaker w/one from a big box store and she is now off and running! THX for  the good advice!

The only part # I see is the one I tittle of the post.....Am I not looking in the right spot on the condenser ?
