Window Air Conditioner Troubleshooting Tips:

  • If the unit stops working completely, make sure the electrical cord has not been damaged and that the wall outlet is still “hot”. Plug in another electrical device to the outlet to check this. If the second electrical device does not work, check that the breaker has not been tripped or turned off. If the wire to the unit has been damaged, replace the wire or call an electrician. This is one of the most common air conditioner troubleshooting problems and is very easy to correct. A dedicated circuit may be required if the breaker is constantly being tripped.
  • Poor air circulation or output is likely due to a dirty filter. Remove the front of the unit as per the manufacturers instructions and remove the filter. If it is brown and dusty looking, wash according to directions or rinse with warm, soapy water until the filter is clean. Avoid any type of chemicals and do not push or damage the filter. Use a fin cleaner or a very soft brush to clean the aluminum fins that act as the cooling mechanism. Don’t use water as this can actually make the dirt turn to mud and cause further damage.
  • Check to make sure the blower fan is working. If the air conditioning unit is not making any sound or is making an unusual noise it is likely the fan or the fan motor. You will need to call a repair person for this.
  • If the unit has plastic dials on the front to set the temperature and turn the unit on and off, check to make sure the knobs are properly seated on the hub, resulting in an actual on or off connection being made. In older units the dial and the hub can become worn, allowing the dial to rotate on the hub without changing the hub position. If the knob or dial turns very easily and does not give resistance, this is likely the problem. Position the knob or dial and hub in the off position and use an epoxy glue to fix the dial and hub together. Allow to dry using the manufacturers suggestions before turning.
