Always see to it the air conditioning unit is unplugged or disconnected from any electrical power source before trying any cleaning or repair work. Window mounted air conditioning troubleshooting tips consist of the following:
If the unit stops working entirely, check that the electrical cord has not been damaged and that the wall plug in is still “hot”. Plug in any other electrical device into the outlet to check this. If the 2nd electrical device does not work, check that the breaker has not been shut off. If the wire to the unit has actually been damaged, replace the wire or call an electrician. This is one of the most common air conditioning troubleshooting problems and is really simple to correct. A dedicated circuit may be needed if the breaker is regularly being tripped.
Poor air circulation or output is most likely due to a filthy filter. Remove the front of the unit as per the makers directions and remove the filter. If it is brown and dirty looking, clean according to instructions or rinse with warm, soapy water until the filter is clean. Avoid any kind 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.

Check to see to it the blower fan is working. If the air conditioning unit is not making any noise or is making an uncommon noise, it is most likely the fan or the fan motor. You will have to call a repair person for this.
If the unit has plastic dials on the front to set the temperature level and turn the unit on and off, check to ensure that the knobs are properly seated on the center, leading to an actual on or off connection being made. In older units, the dial and the hub can become worn, allowing the dial to turn on the hub without altering the hub position. If the knob or dial turns really easily and does not offer resistance, this is most likely the problem. Position the knob or dial and hub in the off position and use an epoxy glue to repair the dial and hub together. Allow to dry using the makers recommendations before turning.
Various other problems can consist of the thermostat within the unit becoming damaged or an electrical short or malfunction within the unit itself. A repair person will often ask if you have tried these standard air conditioning troubleshooting suggestions before asking you to bring the unit in for repair.
