I've read thru A LOT of threads on this topic and I'm hoping someone can help. and I'm hoping it's not a repost.
My issue started with the Thermistor problem where the unit would start running, but temp would very quickly rise past 105 (shut off) and continue on to 126.
I replaced the thermistor and a new pad (it was toast).
When I buttoned it back up and powered on, the service heater light came on immediately and fan did not start turning at all.
I looked on the board and the AFS led was lit.
I replaced the AFS and still the same status. If i jump the AFS wires, the heater light comes on, but no fan.
Prior to ordering a new board, I rapped on the fan motor and hosing. No luck.
I can manually spin the fan in the housing and it would turn freely with the tip of a screwdriver.
I unplugged the motor and jumped (120v) the to see if it would run. It would run at a very low speed.
So, I replaced the board and I am still at the same status. Service heater light, AFS and no fan start (at all).
Your help is greatly appreciated.
