A window unit, generally referred to as a window air conditioner, is nice for cooling a single room or a gaggle of rooms that do not need 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 educated technician. There are minor steps you could take to maintain your window air conditioner working robust.
Throughout the winter months, window items ought to be eliminated and saved indoors in a clear, dry space. In case you are storing your window air conditioner within the basement, you’ll want to elevate it to verify 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 ought to be unplugged and discharged. Failing to take action may lead to extreme, and doubtlessly deadly, electrical shock.
Sustaining Fundamental Parts
(THESE PROCEDURES SHOULD ONLY BE ATTEMPTED BY A TRAINED TECHNICIAN)
The filter, energy wire, coils, change, thermostat, drain ports and fan are vital to service on a routine foundation to keep away from severe issues. Typical pointers for sustaining these elements 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 ought to be eliminated, cleaned and changed. If you happen to reside in a very arid local weather, this may occasionally should be performed extra regularly. Most window air conditioners have a washable filter that appears like a sponge.
Clear 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 sort.
Energy Twine
In case your air conditioner stops working and you believe you studied that it’s not getting energy, there might be an issue with the ability wire. Energy cords might grow to be worn and fail to produce electrical energy to the air conditioner. To verify the wire, take away the management panel. Unscrew the wire terminals after which connect a check 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 greater than zero, change the wire.
Evaporator and Condenser Coils
Clear the evaporator and condenser coils the identical time you clear 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 may occasionally should be performed extra regularly. The coils could be cleaned with a vacuum cleaner hose. If the fins on the coils grow 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 ability wire is working, you will have a defective change. To verify, 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 sort.
Thermostat
The thermostat can be situated behind the management panel. If you happen to consider you will have an issue along with your thermostat, right here is easy methods to check 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 bigger 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 by a drain port. At this level, the water is blown towards the condenser coil, the place it’s dissipated.
Drain ports can grow to be soiled and get clogged with particles. This ends in water leakage, often by the underside of the entrance grille. To forestall clogging, clear the drain with a chunk of wire. Do that firstly of each cooling season and when your unit begins to leak.
Fan
In case your fan shouldn’t be working or whether it is significantly noisy, it’s often attributable to free or soiled fan blades. Observe these steps to restore the fan:
1) Find the fan inside the cupboard.
2) Use a soft material and/or vacuum to scrub 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) If you happen to suspect a defective motor, check 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 울산 에어컨청소.
To take away the fan motor, take away the fan blades, energy wires and mounting bolts. Set up a brand new motor by reversing this process. If the condenser coil prevents motor elimination, don’t try to take away the motor. Name an expert.
If some other issues happen with the motor, compressor or coils, an expert service individual ought to be referred to as.
By doing easy upkeep and repairs as described on this article, you possibly can considerably lengthen the life and effectivity of your window air conditioner.
