I have a trane AC with gas heater. The blower will no come on, even when I put the fan on on. I also tried jumping the red and green wires. I opened the fan compartment and pressed the door switch, with the thermostat fan set to ON. I hear several clicks and the red light on the control panel blinks slowly, but the fan does not come on. The power is hot to the door switch, and then hot to the control panel when the i press the door switch, but there is no power to the fan. If I hook the black wire from the fan directly to the door switch it will run.
I do not see a model number for the unit. The wiring diagram inside the panel says "Integrated Furnace Control D341122P01, replace with CNT02789 or CNT02183.
Do you think that the control panel is bad and needs to be repalced ?
Anyone have any other trouble shooting guidelines ?
An HVAC place told me that the board to replace this one is now a CNT03797 - $149.
I pulled the control board out and it has a burnt spot on the back, so I am sure that the board is bad. I am ordering a new board now. Thanks anyway.
