Always ensure the air conditioner is unplugged or disconnected from any electrical power source before attempting any cleaning or repair work. Window mounted air conditioning troubleshooting pointers include 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 been damaged, replace the wire or call an electrician. This is one of the most typical air conditioning troubleshooting problems and is really simple to correct. A dedicated circuit might be required if the breaker is constantly being tripped.
Poor air circulation or output is likely due to an unclean filter. Remove the front of the unit as per the makers instructions and remove the filter. If it is brown and dusty looking, wash according to directions or rinse with warm, soapy water till 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. Do not use water as this can in fact, make the dirt turn to mud and cause additional damage.
Check to ensure the blower fan is working. If the cooling unit is not making any noise or is making an unusual sound, it is likely the fan or the fan motor http://www.planoair.com/ac-repair-heating-repair-mckinney-tx.html . You will need to call a repair expert 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 hub, resulting in an actual on or off hookup being made. In older units, the dial and the hub can become worn, enabling the dial to turn on the hub without changing the hub position. If the knob or dial turns really easily and does not give resistance, this is likely the issue. 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 suggestions before turning.
Various other problems can include the thermostat within the unit becoming damaged or an electrical short or breakdown within the unit itself. A repair expert will frequently ask if you have actually tried these basic air conditioning troubleshooting suggestions before asking you to bring the unit in for repair work.
