    No blower motor power in heat
    I am working on a fedders corporation electric air handler and I cannot get the blower motor to turn on with heat. It is a single speed blower set up and the blower comes on when switched to fan and on auto with the ac. Installed new digital thermostat, blower relay and contactor. Contactor gets energized and power to the heat strips just don't know why the relay isn't getting energized when called for heat

    The blower is brought on by M1 & M2 on the heat sequencer(heat mode). Its not uncommon to have that part go bad. When the heat sequencer closes it send voltage through the normally closed contacts on the blower relay. I hope this helps good luck
