My outside unit works but my inside unit does nit turn on, its a bryant a/c system. On the unit it says the circuit board is built into the blower motor. The transformer buzzes. Can I replace the circuit board without replacing the blower motor?
I have been told I did not answer the qestion,simply put you can not switch off beause the wiring is wrong.
I Have not dealt with this exact problem,it could be the blower motor is faulty,a buzzing sound maybe locked bearings or winding fault,can not be more precise with inormation I have,Steve uk engineer best wishes.It occured to me the buzzing noise maybe condensate pump running.NOises can be hard to pinpoint,check this out first.
