Heating, Air Conditioning, Fridge, HVAC/Condensor Fan Trane xl1400 heatpump


Model# TWY042B100A1
Trane XL1400 Heatpump

Condenser unit fan won't run.
Variable speed type.
Fan motor has voltage to it
Compressor comes on, runs but no fan.
Fan motor spins freely.

Troubleshooting guide says it may be the run cap., but I don't see one in the electrical drawing or physically.

Could only find a run and start for the compressor.

Could it be the defrost timer board?
Could not find a part number for it.

Thanks for your help in advance.
