A window unit, generally referred to as a window air conditioner, is nice for cooling a single room or a gaggle of rooms that wouldn’t have partition partitions. A window air conditioner consists of a blower, fan, compressor, evaporator coil, condenser coil, thermostat and filter.
Inside upkeep to the sealed refrigeration circuit (coils, compressor and motor) ought to be left to a skilled technician. There are minor steps you can take to maintain your window air conditioner operating robust.
Through the winter months, window models ought to be eliminated and saved indoors in a clean, dry space. In case you are storing your window air conditioner within the basement, make sure to elevate it to ensure it doesn’t get uncovered to water. At all times maintain your unit within the upright place to stop oil and refrigerant migration.
Warning: Earlier than any work is completed in your equipment, it ought to be unplugged and discharged. Failing to take action might end in extreme, and doubtlessly deadly, electrical shock.
Sustaining Fundamental Elements
(THESE PROCEDURES SHOULD ONLY BE ATTEMPTED BY A TRAINED TECHNICIAN)
The filter, power twine, coils, swap, thermostat, drain ports and fan are vital to service on a routine foundation to keep away from critical issues. Typical tips for sustaining these components are as follows (BE SURE TO REFER TO YOUR OWNER’S GUIDE FOR SPECIFICS ON YOUR UNIT):
Filter
Earlier than each cooling season and as soon as a month throughout the cooling season, the filter ought to be eliminated, cleaned and changed. In the event you reside in a very arid local weather, this may occasionally must be accomplished extra incessantly. Most window air conditioners have a washable filter that appears like a sponge.
Clean filters with a gentle detergent and water, rinsing effectively. Let the filter dry utterly earlier than changing. In case your window air conditioner comes with a fiberglass furnace fashion filter, don’t wash it; change it with a brand new filter of the identical sort.
Power Wire
In case your air conditioner stops working and you think that it’s not getting power, there might be an issue with the power twine. Power cords could turn into worn and fail to supply electrical energy to the air conditioner. To verify the twine, take away the management panel. Unscrew the twine terminals after which connect a take a look at wire throughout the naked lead wires.
Hook the clips of a volt-ohm-millimeter (VOM) set to the RX1 scale to the prongs on the twine’s plug. If the meter reads zero, the twine is functioning. If the meter reads larger than zero, change the twine.
Evaporator and Condenser Coils
Clean the evaporator and condenser coils the identical time you clean the filter; earlier than the beginning of the cooling season and as soon as a month throughout the season. In case your space is especially dusty, this may occasionally must be accomplished extra incessantly. The coils could be cleaned with a vacuum cleaner hose. If the fins on the coils turn into bent, use a fin comb out of your native ironmongery shop to straighten them.
Swap
The selector swap, behind the management panel, turns the window air conditioner on and off. If the air conditioner doesn’t run on any setting, and you’ve got already made certain that the power twine is working, you’ll have a defective swap. To verify, take away the management panel and see if there’s burnt insulation or black marks on the terminals. If that’s the case, change your swap with one of many similar sort 울산에어컨청소.
Thermostat
The thermostat can also be situated behind the management panel. In the event you consider you could have an issue together with your thermostat, right here is the way to take a look at and change it:
1) Take away the grille and management panel. There will likely be a temperature sensing bulb extending from the thermostat to the face of the evaporator coil
2) Rigorously take away the thermostat, noting the place of the sensing bulb. It should be changed within the precise spot.
3) Test the thermostat with the VOM setting on the RX1 scale. Clip the probes to the thermostat terminals and switch the temperature management to the coldest setting. Your meter ought to learn zero if the thermostat is working correctly. If the studying is larger than zero, change the thermostat with a brand new one of many similar sort.
Drain Ports
The evaporator coil condenses water vapor from the air and funnels it via a drain port. At this level, the water is blown towards the condenser coil, the place it’s dissipated.
Drain ports can turn into soiled and get clogged with particles. This ends in water leakage, often via the underside of the entrance grille. To forestall clogging, clean the drain with a bit of wire. Do that at first of each cooling season and when your unit begins to leak.
Fan
In case your fan is just not working or whether it is significantly noisy, it’s often brought on by unfastened or soiled fan blades. Comply with these steps to restore the fan:
1) Find the fan inside the cupboard.
2) Use a mushy material and/or vacuum to clean out any particles.
3) Test tightness of all blades. Vibration can loosen fan fasteners. Use a screwdriver or Allen wrench to tighten screws that join the fan hub to the motor shaft.
4) In case your fan has oil ports, apply a number of drops of 20-weight non-detergent motor oil.
5) In the event you suspect a defective motor, take a look at with the VOM on the RX1 scale. Join VOM probes to disconnected terminal wires.
If the meter reads between 3 and 30 ohms, your motor is functioning correctly. In case your meter reads zero or this can be very excessive, change the motor.
To take away the fan motor, take away the fan blades, power wires and mounting bolts. Set up a brand new motor by reversing this process. If the condenser coil prevents motor removing, don’t try and take away the motor. Name knowledgeable.
If another issues happen with the motor, compressor or coils, knowledgeable service particular person ought to be referred to as.
By doing easy upkeep and repairs as described on this article, you possibly can considerably prolong the life and effectivity of your window air conditioner.
