If your Westinghouse Air Conditioner won't start, begin by checking the power supply circuit. Look for any tripped breakers or blown fuses. Measure the insulation resistance to ground to check for leakage. Inspect the power supply circuit for defective contacts or leak current. Ensure the remote controller is properly set and, if needed, change the batteries.
Why is my Westinghouse WHM24DMA21S Air Conditioner not cooling/heating well?
If your Westinghouse Air Conditioner isn't cooling or heating properly, several factors could be responsible. First, try cleaning the heat exchanger of the outdoor unit, such as the condenser. Also, ensure there are no heating devices operating indoors. Maintaining good air tightness indoors can help, so limit frequent opening and closing of doors and windows. Check for any obstructions blocking the outdoor heat exchanger, and remove them. Finally, double-check the temperature settings to ensure they are correctly configured.
How to fix water leakage from my Westinghouse WHM24DMA21S Air Conditioner?
If your Westinghouse Air Conditioner is leaking water, it could be due to a blocked or broken drainage pipe. In this case, change the drainage pipe. Another potential cause is that the wrap of the refrigerant pipe joint is not completely closed. To fix this, re-wrap the joint tightly.
Why does the compressor in my Westinghouse WHM24DMA21S Air Conditioner start and stop frequently?
