  Philip WilsonSep 12, 2025
  If your Maytag Air Handler isn't working, it could be due to several reasons: * There might be loose or disconnected wiring at the circulator motor power leads, so you should tighten or correct the wiring connection. * For 3/4 Hp and 1 Hp models, there could be an open circuit in the inductor or loose wiring at the inductor. Verify the circuit and replace the inductor if it's open or shorted. * The circulator blower motor may have failed, so check the motor.
