Trane Model BLU108F Lights but trips breaker

My Trane Model BLU108F Lights and heats but when the fan should turn on the breaker trips. The A/C runs fine.

Welcome to the forums.

Does the breaker trip when you put the thermostat in FAN ON mode ?

If it does then you have to check the blower motor. Either the motor or the wiring has a short.

Kicks breaker

I believe that model runs a different fan speed in heat and AC you have lost the windings in the blower fan for the heat speed. Replace the blower motor. (check the wiring first of course for a short but most likely a new motor is in order)
