Troubleshoot Maytag Window Air Conditioners and Clean an Air Conditioner Return Vent Cover

Maytag air conditioners help control the temperature of rooms in your home during hot summer months. Though the air conditioning units run optimally under most conditions, you may occasionally have problems with the power, warm air coming out of the unit or ice forming on the air conditioner. These problems often do not require the assistance of a service technician.

How to Troubleshoot Maytag Window Air Conditioners

Troubleshoot your air conditioner to determine the problem and fix it yourself. Check that the power cord is securely plugged into the electrical outlet and that the power switch is in the On position. Plug another device into the electrical outlet to ensure it is working.

If the other device does not work, check the fuse box for a blown fuse or tripped circuit breaker. Replace the fuse and reset the circuit breaker as needed. Wait for the air compressor to turn on if you shut off then turned on the air conditioner quickly or if you quickly switched the temperature control to a warmer setting and then a colder setting.

Turn the temperature control to a colder setting. If the room is too cool, the sensor within the air conditioner will not start the compressor until the temperature control is set to a colder setting. Adjust the switch from Fan to Cool.

When set to Fan, the air conditioner circulates the air within the room. It will not produce colder air until it is set to Cool.

How to Clean an Air Conditioner Return Vent Cover

Turn off your central air conditioning unit before beginning. Release the top of the return vent cover. Allow the cover to fall backward into your hands.

Grip each side of the vent cover and pull up. Then pull the bottom outward to release it from the holders. Take the vent cover outside on your driveway or patio or to your bathtub to clean.

Spray the fins with an all-purpose cleaner or put some warm water in a spray bottle, add a couple of drops of dish-washing liquid, replace the sprayer, shake to mix and spray the fins with the solution. Wait two to three minutes for the cleaning solution to begin to loosen the dirt and dust. Scrub any stubborn spots with an old toothbrush.

Spray clean with water from a hand-held shower sprayer or a hose with a sprayer attachment, and dry with a clean towel. Use a hair dryer set on high to evaporate any water present in the joints to prevent rust. Re-attach the vent cover.

The return-air duct in your house pulls in the air in your home and cools it before it is redistributed through registers in each room. Over time, as dust and dirt-laden air is pulled through the vent cover of your air conditioner return, the particles will collect and leave the fins noticeably dirty. This is a normal occurrence, and you can restore your return vent cover back to its clean appearance with the aid of a few household products.
