Trane Diagnostics, or, What are those pretty green lights for?
Before I call my local guy, who installed my system, I was curious to know what is the cause of my problem. My TRANE 4TEE3F31A1000A air handler has stopped working. It only comes on when you put it in Emergency Heat mode. In normal mode, the thermo just clicks, lights up, and nothing happens. No fan, no compressor. There are 4 LEDS on the control board, 1 labeled CFM, 1 labeled FAN, and 2 that are not labeled. The CFM one is flickering, not blinking, and does it in a sequence, so i know it is trying to say something. The FAN light is off, and the 2 others are dimly lit.
What could possibly cause this?
Thanks in advance,
