A window unit, generally known as a window air conditioner, is nice for cooling a single room or a bunch of rooms that would 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) must be left to a educated technician. There are minor steps that you could take to maintain your window air conditioner working sturdy.
Throughout the winter months, window models must 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 verify 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 finished in your equipment, it must be unplugged and discharged. Failing to take action may lead to extreme, and probably deadly, electrical shock.
Sustaining Fundamental Components
(THESE PROCEDURES SHOULD ONLY BE ATTEMPTED BY A TRAINED TECHNICIAN)
The filter, power wire, coils, swap, thermostat, drain ports and fan are vital to service on a routine foundation to keep away from severe 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 in the course of the cooling season, the filter must be eliminated, cleaned and changed. Should you stay in a very arid local weather, this may increasingly should be executed extra continuously. Most window air conditioners have a washable filter that appears like a sponge.
Clean filters with a light detergent and water, rinsing nicely. Let the filter dry utterly earlier than changing. In case your window air conditioner comes with a fiberglass furnace type 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 think that it isn’t getting power, there might be an issue with the power wire. Power cords could turn out to be worn and fail to supply electrical energy to the air conditioner. To test the wire, take away the control 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 increased 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 in the course of the season. In case your space is especially dusty, this may increasingly should be executed extra continuously. The coils could 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.
Swap
The selector swap, behind the control 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 wire is working, you could have a defective swap. To test, take away the control panel and see if there may be burnt insulation or black marks on the terminals. If that’s the case, change your swap with one of many similar kind.
Thermostat
The thermostat can also be positioned behind the control panel. Should you consider you could have an issue along with your thermostat, right here is methods to take a look at and change it:
1) Take away the grille and control panel. There might be a temperature sensing bulb extending from the thermostat to the face of the evaporator coil
2) Fastidiously take away the thermostat, noting the place of the sensing bulb. It have to 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 control 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 a drain port. At this level, the water is blown towards the condenser coil, the place it’s dissipated.
Drain ports can turn out to be soiled and get clogged with particles. This ends in water leakage, often by the underside of the entrance grille. To stop clogging, clean the drain with a chunk of wire. Do that at the start of each cooling season and when your unit begins to leak 울산에어컨청소.
Fan
In case your fan is just not working or whether it is significantly noisy, it’s often attributable to unfastened or soiled fan blades. Observe these steps to repair the fan:
1) Find the fan inside the cupboard.
2) Use a gentle cloth 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) Should 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 removal, don’t try to take away the motor. Name knowledgeable.
If every other issues happen with the motor, compressor or coils, knowledgeable service particular person must 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.
