How to Maintain a Window Air Conditioner

A window device, commonly named a window air conditioner, is fantastic for cooling a solitary room or a team of rooms that do not have partition partitions. A window air conditioner consists of a blower, fan, compressor, evaporator coil, condenser coil, thermostat and filter.

Inner servicing to the sealed refrigeration circuit (coils, compressor and motor) need to be still left to a trained technician. There are small steps that you can just take to continue to keep your window air conditioner managing robust.

Through the winter season months, window models should be eliminated and stored indoors in a cleanse, dry location. If you are storing your window air conditioner in the basement, be certain to elevate it to make certain it does not get exposed to drinking water. Usually maintain your device in the upright position to avoid oil and refrigerant migration.

Warning: Right before any work is performed on your equipment, it ought to be unplugged and discharged. Failing to do so could final result in significant, and potentially deadly, electrical shock.

Retaining Basic Factors
(THESE Strategies Should really ONLY BE Tried BY A Qualified TECHNICIAN)

The filter, ability cord, coils, switch, thermostat, drain ports and fan are crucial to service on a plan basis to keep away from significant problems. Normal guidelines for preserving these areas are as follows (BE Guaranteed TO REFER TO YOUR OWNER’S Information FOR Particulars ON YOUR Device):


Right before every cooling season and the moment a month for the duration of the cooling season, the filter must be removed, cleaned and changed. If you are living in a notably arid local climate, this may possibly have to have to be done more regularly. Most window air conditioners have a washable filter that appears to be like a sponge.

Clear filters with a gentle detergent and h2o, rinsing nicely. Let the filter dry fully ahead of changing. If your window air conditioner arrives with a fiberglass furnace style filter, do not wash it swap it with a new filter of the very same form.

Power Twine

If your air conditioner stops doing work and you suspect that it is not obtaining ability, there could be a problem with the electric power wire. Energy cords could turn out to be worn and fail to source energy to the air conditioner. To check the twine, get rid of the control panel. Unscrew the cord terminals and then attach a take a look at wire across the bare guide wires.

Hook the clips of a volt-ohm-millimeter (VOM) established to the RX1 scale to the prongs on the cord’s plug. If the meter reads zero, the twine is working. If the meter reads better than zero, substitute the twine.

Evaporator and Condenser Coils

Clear the evaporator and condenser coils the exact time you cleanse the filter prior to the start of the cooling season and the moment a month through the season. If your area is especially dusty, this may perhaps will need to be finished much more commonly. The coils can be cleaned with a vacuum cleaner hose. If the fins on the coils develop into bent, use a fin comb from your community hardware retailer to straighten them.


The selector change, guiding the control panel, turns the window air conditioner on and off. If the air conditioner does not run on any environment, and you have currently made sure that the electricity cord is functioning, you may well have a defective switch. To check out, remove the control panel and see if there is burnt insulation or black marks on the terminals. If so, replace your switch with a single of the very same style.


The thermostat is also located powering the handle panel. If you believe that you have a challenge with your thermostat, in this article is how to exam and replace it:

1) Remove the grille and handle panel. There will be a temperature sensing bulb extending from the thermostat to the experience of the evaporator coil

two) Diligently remove the thermostat, noting the placement of the sensing bulb. It must be changed in the actual place.

3) Check the thermostat with the VOM location on the RX1 scale. Clip the probes to the thermostat terminals and turn the temperature manage to the coldest placing. Your meter should read through zero if the thermostat is operating effectively. If the reading through is larger than zero, change the thermostat with a new a single of the identical sort.

Drain Ports

The evaporator coil condenses h2o vapor from the air and funnels it as a result of a drain port. At this level, the h2o is blown from the condenser coil, exactly where it is dissipated.

Drain ports can grow to be dirty and get clogged with debris. This final results in h2o leakage, generally through the base of the front grille. To avert clogging, clean the drain with a piece of wire. Do this at the beginning of each cooling year and when your device starts off to leak.


If your admirer is not functioning or if it is specifically noisy, it is ordinarily induced by free or soiled enthusiast blades. Comply with these steps to repair the fan:

1) Find the supporter inside the cupboard.

2) Use a tender fabric and/or vacuum to clean out any debris.

three) Test tightness of all blades. Vibration can loosen supporter fasteners. Use a screwdriver or Allen wrench to tighten screws that connect the enthusiast hub to the motor shaft.

four) If your enthusiast has oil ports, utilize a couple drops of twenty-excess weight non-detergent motor oil.

five) If you suspect a faulty motor, exam with the VOM on the RX1 scale. Join VOM probes to disconnected terminal wires.

If the meter reads among 3 and 30 ohms, your motor is working adequately. If your meter reads zero or it is exceptionally higher, change the motor.
