To repair a Danby air conditioner, you first must identify the actual problem, and then clean or replace the affected component. Common problems with Danby air conditioners include power supply issues, dirty condenser coils, clogged air filters, and defective fan motors.
If a Danby air conditioner does not cool, first confirm that the device is plugged into a working electrical outlet and that the thermostat is set correctly. Check to see if the air filter is clogged or if the condenser coils are dirty. Clogged air filters and dirty condenser coils reduce the cooling capacity of an air conditioner greatly and must be cleaned or replaced. If the problem persists, examine the thermistor and the temperature control thermostat, and replace them if faulty.
If the air conditioner is noisy or loud, the fan motor might be worn out. The fan motor contains bearings that are permanently lubricated. If this lubrication breaks down, the fan motor becomes noisy and has to be replaced. If this does not solve the problem, examine the fan blade to see if it has broken or rubs on the fan housing.
If none of these repair methods fix the problem, contact a Danby professional for assistance.
