1. Cleaning condenser coil.
An accumulation of dirt and dust prevents the condenser coil from removing heat, making your unit cool poorly,
run constantly, or even stop completely if the compressor overheats. Clean coil using a vacuum cleaner with a
wand attachment. If the coil is greasy, wash it with warm soapy water and a bristle brush, taking care not to
drip water on other parts of your unit.
2. Cleaning drain and drain pan.
Remove the perforated panel on the extreme left interior, along with the adjoining back interior panel. Clean
the drain using an oven baster to force a solution of hot water and baking soda or bleach into the opening. To
clear a stubborn clog, insert a length of ¼” round plastic tubing into the drain and push it through to the drain
pan, then pull it out. Wash the pan regularly with a solution of warm baking soda and water.
3. Checking the door seal.
Open the door and examine all four sides of the door gasket for
tears. Feel the gasket for brittleness or cracks. If the gasket shows
damage replace it. If not, close the door and check the seal be-
tween gasket and cabinet for obvious gaps. Next open the door
and shut it on a dollar bill then slowly pull it out of the door. If the
gasket seals properly, you will feel tension as it grips the bill.
Repeat this test all around the door. If the gasket doesn’t seal
tightly, replace gasket after first checking the door for sagging,
warping.
4. Servicing the condenser fan.
Inspect the condenser fan motor by removing the mechanical housing
cover to gain access. Unplug the unit. Clean the fan blade, and turn it
to see if the blade rotates freely. If the motor binds, replace it. If the
blade is damaged, unscrew the nut that holds it to the motor shaft and
pull it off. Install a new fan blade, replacing any washers, and tighten
the nut.
To test the condenser fan motor disconnect the wires to the fan
motor. Set a multimeter at RX10 and touch one probe to each termi-
nal. The multimeter needle should show approximately 45 to 50 ohms
resistance; a lower reading means the motor is faulty.
