Customer Question

Hi Phil, I have an xr11 2ttr1036a1000aa trane heat pump that is doing a terrible job of cooling

Is the indoor and outdoor both coming on? If so can you tell if the compressor,not just fan is coming on in outdoor unit?

Customer: replied 9 months ago.
it sounds like more than a fan outside and the inside is definitely running. We are getting mildly cool air coming out of the registers
Expert:  airheatman replied 9 months ago.

Feel of the large copper pe leaving the outdoor unit and tell me if it is "beer can cold" and sweating.

Customer: replied 9 months ago.
the tube that is wrapped with foam?
Expert:  airheatman replied 9 months ago.

Yes, either feel inside the foam or at the valve on unit where it connects

Customer: replied 9 months ago.
Roger... warm not cold or sweating. Time to take the cover off and multimeter/jump some stuff?
Expert:  airheatman replied 9 months ago.

If it is not cold, either compressor is not coming on or we are low on Freon. Do you have an amp meter to clamp on a compressor wire to make sure it is drawing amps?

Customer: replied 9 months ago.
I have the $200 variety of a multi-meter no clamp like they would use at the auto parts store to verify your alternator functioning.
Expert:  airheatman replied 9 months ago.

OK without the meter,we first need to get close enough to compressor to see if we hear it running,

Customer: replied 9 months ago.
how to proceed? do I need to power everything off, turn off power at the circuit breaker and then remove a side panel?
Expert:  airheatman replied 9 months ago.

Yes, then turn back on and se if you can verify compressor is running.If you have gauges, that will tell us exactly what is going on.

Customer: replied 9 months ago.
I will get to that part shortly.
Expert:  airheatman replied 9 months ago.

Sounds good,That will tell us what we need
