A window unit, generally referred to as a window air conditioner, is nice for cooling a single room or a gaggle of rooms that should not 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 skilled technician. There are minor steps that you could take to maintain your window air conditioner operating sturdy.
In the course of 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, make sure to elevate it to verify it doesn’t get uncovered to water. All the time preserve your unit within the upright place to forestall 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 may lead to extreme, and probably deadly, electrical shock.
Sustaining Primary Elements
(THESE PROCEDURES SHOULD ONLY BE ATTEMPTED BY A TRAINED TECHNICIAN)
The filter, power wire, coils, swap, 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 likely should be achieved extra continuously. Most window air conditioners have a washable filter that appears like a sponge.
Clean filters with a gentle detergent and water, rinsing nicely. Let the filter dry fully 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 kind.
Power Twine
In case your air conditioner stops working and you watched that it isn’t getting power, there could possibly be an issue with the power wire. Power cords could develop into worn and fail to supply electrical energy to the air conditioner. To examine the wire, take away the management panel. Unscrew the wire 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 wire’s plug. If the meter reads zero, the wire is functioning. If the meter reads larger than zero, change the wire.
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 likely should be achieved extra continuously. The coils could be cleaned with a vacuum cleaner hose. If the fins on the coils develop into bent, use a fin comb out of your native ironmongery store to straighten them.
Change
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 positive that the power wire is working, you’ll have a defective swap. 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 swap with one of many similar kind.
Thermostat
The thermostat can be positioned behind the management panel. In the event you consider you’ve got an issue together with your thermostat, right here is easy methods to take a look at and change it:
1) Take away the grille and management panel. There can 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 울산에어컨청소.
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 in opposition to the condenser coil, the place it’s dissipated.
Drain ports can develop into soiled and get clogged with particles. This ends in water leakage, often via the underside of the entrance grille. To stop clogging, clean the drain with a chunk of wire. Do that initially 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 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 just a few 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 knowledgeable.
If some other issues happen with the motor, compressor or coils, knowledgeable service individual needs to be referred to as.
By doing easy upkeep and repairs as described on this article, you’ll be able to considerably prolong the life and effectivity of your window air conditioner.
