Mitsubishi Air handlers

Official Mitsubishi air handler parts

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

Clearing a clogged condensate drain line in your Mitsubishi air handler

  • Shut off the house circuit breakers for your air handler to disconnect electrical power.
  • Pull the float switch out and vacuum water from the condensate drain system through the float switch hole.
  • Use a plumber's snake to clear the drain line to the outside of your home.
  • Pour water through the drain line to make sure it's clear.
  • Reinstall the float switch and restore power to the air conditioner.
  • Pour one cup of liquid bleach through the drain line every six months to keep the drain line clear of algae.

Common parts that fail in Mitsubishi air handlers

  • Blower fan motor. The blower fan motor spins the blower wheel to circulate air through the evaporator and into your home. You'll need to replace the blower fan motor if it's getting current but won't run.
  • Evaporator coils. Evaporator coils are part of the heat exchange system. These coils remove heat from the air. If the coils are dirty or damaged, they'll need to be cleaned or replaced to work properly.
  • Thermostat. The thermostat detects the temperature inside your home and turns the air handler and air conditioner or heater on and off to maintain the set temperature inside your home. You'll need to replace the thermostat if it isn't detecting temperature properly or it isn't turning on the air handler and air conditioner or heater.
  • Air filter. The air filter removes fine particulates from the air to protect the internal components of the air handler and helps improve the air quality inside your home. If the filter is too dirty, then it may restrict air flow and will need to be replaced.
