Window Air Conditioner / Window AC Trouble Diagnosis Chart Is there anything I need to do to my window AC before I start it for the summer? Yes, Check and make sure the condenser and evaporator coilsYou can use a garden hose to wash them out. it and remove it from the window to do this.

Also take special care not to get the switches and the fan motor wet. Be sure to let everything dry out before plugging it back in. Also oiling the fan motor if it has oil ports is required. Note: not all fan motors have oil ports. Some are sealed from the factory and cannot be oiled. Check/Clean the Air Filter. Oil Ports on the Fan Motor Zoom Spout Fan Oiler Great for oiling the fan motor Email our parts dept. for zoom spout oilers Great for straightening out those bent fins dept. for fin comb kits How do I oil the fan? Remove the oil port caps, some are plastic, some are metal. few drops of oil. The oil is a light weight turbine type oil. How do I check the compressor? Using a ohm meter, and the compressor is cool to the touch, and the ac is unplugged, Disconnect the wiring to the compressor and mark where the wires went. Ohm out the terminals from common to start andYou should have continuity across both.

Check from each terminal, (with the wires disconnected) to ground or a piece of tubing coming out of the compressor. You should have no continuity. you have continuity to ground the compressor is shorted to ground and will If the compressor has failed and the A/C  compressor is not under warranty, then it's probably not worth repairing as compressors go for How do I check the overload? With it disconnected check it for continuity. A/C wont come on Check the house fuses or the house breaker. Check the selector switch. Air for the unit does not feel cold enough Fan selector set to "Fan Only" position Thermostat set at too warm a setting Exhaust vent control set at "Open" position. Thermostat Sensing bulb not properly located Unit low on refrigerant Air Conditioner cooling but room too warm Air directional louvers improperly positioned Init front is blocked by draperies, furniture, etc. Outside louvers blocked by bricks, siding etc.

Insufficient cooling capacity for room sizehow ac recovery machine works Improper installation - Make sure unit is slightly tipped towardshow to dispose of old ac unit Blockage in drain - clean drain - remove unit from the window -indoor ac/heating units disconnect power and wash out with garden hose - let dry thoroughly before re- applying power. Water dripping outside at the back of the unit Unit operating in a humid environment - Normal operation Water hitting condenser fan blade.Most window ac's have what they call a slinger ringIt's a ring that runs around the outer edge of the condenser fan blade and slings water up on the condenser coil to help it cool I drilled holes in the bottom of my air conditioner to make

it drain and cool better You should not drill holes in the ac base. Most window ac's have what they call a slinger ring . It's a ring that runs around the outer edge of the condenser fan blade and slings water up on the condenser coil to help it cool better. If you drill holes in the bottom , then the a/c will not hold enough water to sling up on the coil. How big of an AC do I need to cool my space? We recommend 1 Ton, (12,000 BTU) for each 500 sq. ft in a normal house and 1 Ton, (12,000 BTU) for each 400 sq. ft in a manufactured The coil on the front of the AC keeps freezing up or thermostat not cycling properly A sign of low on charge is part of the coil frosting or freezing up and the unit not cooling well. What type of refrigerant do window AC's use? Most units use R-22 Freon. Look on the model and serial tag toIt will usually show how much refrigerant it holds also. A special license is required to handle and purchase refrigerant

The fins on my coils are all smashed The fins can be straighten using a fin comb. not effect the unit operation, major fin damage will. Didn't Find Your Answer Here?
