GMC Air handlers

Official GMC air handler parts

GMC air handlers move air through the evaporator and heating element of your central air conditioning unit. GMC uses power blower motors and dependable controls in their air handler units to help keep your home comfortable during every season. When your GMC air handler breaks down, depend on Sears PartsDirect to have the replacement parts you need to fix the problem.

Common replacement parts for GMC air handlers

  • Air filter. The air filter traps dust and lint from air going to the evaporator.
  • Blower motor. The blower motor spins the blower wheel to circulate air through the evaporator and throughout your home.
  • Electronic control board. The electronic control board receives signals from the thermostat and cycles the air handler on and off as needed to maintain the set temperature in your home.

Replacing the wall control thermostat for your GMC air handler

  • Shut off the house circuit breakers for your air handler to disconnect electrical power.
  • Remove the cover of the existing wall control thermostat. Follow the instructions in the owner's manual for the existing thermostat to remove its cover.
  • Remove the thermostat mounting screws and pull the thermostat out from the wall slightly to access thermostat wires.
  • Disconnect the thermostat wires and remove the existing wall control thermostat.
  • Connect the wires to the new wall control thermostat.
