Trane TWX030C100A0 Defrost Board
Went to work on a TRANE TWX030C100A0 and the defrost board has a green light was flashing and making a clicking sound. This is not the original board and the paper work is gone. Anybody know what this means .If I remember right the original board in these units was a lot bigger than this one and had a red light and a wire you moved around to test it. This one has four pins.

FLASH RATE INDICATIONS:
1 — Flash/Second = Normal operation
2 — Flashes/Second = Fault A (Low Delta T) Inoperative Compressor, loss of charge, open amb. sensor, shorted coil sensor.
3 — Flashes/Second = Fault B (20 defrosts terminated on time), and Fault C (High Delta T) SOV stuck in heating, shorted amb. sensor, open coil sensor, closed TXV, OD fan motor failure, OD fan on in defrost, undercharged unit.
4 — Flashes/Second = Fault A & C or A & B
Send me an email (address is in my profile), and I will get some info off to you on these defrost controls.Instead of learning the tricks of the trade, learn the trade.
