A window unit, generally known 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.
Inner upkeep to the sealed refrigeration circuit (coils, compressor and motor) needs to be left to a educated technician. There are minor steps that you may take to maintain your window air conditioner working robust.
Through the winter months, window items needs to be eliminated and saved indoors in a clean, dry space. If you’re storing your window air conditioner within the basement, be sure you elevate it to ensure it doesn’t get uncovered to water. At all times preserve your unit within the upright place to stop oil and refrigerant migration.
Warning: Earlier than any work is finished in your equipment, it needs to be unplugged and discharged. Failing to take action might lead to extreme, and probably deadly, electrical shock.
Sustaining Primary Elements
(THESE PROCEDURES SHOULD ONLY BE ATTEMPTED BY A TRAINED TECHNICIAN)
The filter, power twine, coils, change, thermostat, drain ports and fan are necessary to service on a routine foundation to keep away from severe issues. Typical pointers 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 through the cooling season, the filter needs to be eliminated, cleaned and changed. In the event you stay in a very arid local weather, this will must be achieved extra incessantly. Most window air conditioners have a washable filter that appears like a sponge.
Clean filters with a light detergent and water, rinsing properly. Let the filter dry fully earlier than changing. In case your window air conditioner comes with a fiberglass furnace model filter, don’t wash it; change it with a brand new filter of the identical kind.
Power Wire
In case your air conditioner stops working and you believe you studied that it’s not getting power, there might be an issue with the power twine. Power cords might turn out to be worn and fail to supply electrical energy to the air conditioner. To examine 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 increased 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 through the season. In case your space is especially dusty, this will must be achieved extra incessantly. The coils might be cleaned with a vacuum cleaner hose. If the fins on the coils turn out to be bent, use a fin comb out of your native ironmongery shop to straighten them.
Change
The selector change, 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 positive that the power twine is working, you might have a defective change. To examine, take away the management panel and see if there’s burnt insulation or black marks on the terminals. In that case, change your change with one of many similar kind.
Thermostat
The thermostat can be positioned behind the management panel. In the event you imagine 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 kind.
Drain Ports
The evaporator coil condenses water vapor from the air and funnels it by way of a drain port. At this level, the water is blown towards the condenser coil, the place it’s dissipated 울산 에어컨청소.
Drain ports can turn out to be soiled and get clogged with particles. This leads to water leakage, normally by way of the underside of the entrance grille. To forestall clogging, clean the drain with a chunk of wire. Do that in the beginning of each cooling season and when your unit begins to leak.
Fan
In case your fan shouldn’t be working or whether it is notably noisy, it’s normally 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 soft 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 couple 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 elimination, don’t try and take away the motor. Name an expert.
If every other issues happen with the motor, compressor or coils, an expert service particular person needs to be known 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.
