Heating, Air Conditioning, Fridge, HVAC/Trane system problem
I have been having problems with my Trane XR 15 system the air handler is model 4TEE3610A1000AA. Initially there was no warming with the outside heat pump not running and frozen. Original installer came and replaced blower motor with no result. Replaced control board inside air handler. Showed fault code 3. Personality module changed, various wiring harnesses as well. Again was told by Trane field service rep to replace motor and board. Still fault code 3. Testing the board for voltage showed fluctuating DC voltage from 13 to 15 volts. In diagnosing and with a visit from the field rep, they found 255 volts at the unit. Had power company come out next morning to check and they had 248v. Electrician came out and got same readings. Never 255 at the unit. Installer came again and replaced board. Now shows fault code 7 which is supposed to be stuck relay.
Unit is still under warranty for a few more months and I have lost confidence in Trane as well as the unit for long term. Wait to hear from installer for further. Any ideas would be appreciated.
