5 Common Air Conditioner Compressor Problems to Avoid

A burned out or faulty air conditioner compressor can result to noises coming from the appliance, hard starting or lost cooling capacity. A compressor draws heat filled refrigerant gas from an air conditioner’s components and compresses the low pressure refrigerant to high pressure and temperature. Regular inspection and maintenance practices such as checking compressor support pads helps to avoid such problems.

Start with Simple Checks

A problem with an air conditioner could be as a result of small or minor fault. Carry out simple checks to find out if this starts the appliance. It helps to save time and cost in calling in an expert to look at the appliance. Find out if there is electrical power. Make sure that all settings are properly done as well as operations of system controls. Check that the air filter, duct work and blower fans are in good condition.

Lost Cooling Capacity

This can be avoided by maintaining correct pressure in the component at all times. Check for lower than normal discharge pressure as well as higher than normal suction vacuum. These signs can be an indication of a problem with the air conditioner compressor. A service technician can help correct the problem.

Insufficient Cooling

If the air conditioner compressor takes a longer than “on” cycle with little or no cool air being supplied to the living area, the appliance might have loose or worn compressors. This problem comes about as a result of internal wear in the device. Avoid this problem by installing gauge ports on the compressor and maintain correct pressure in the equipment. Call a service technician to correct this problem. It might require installing a new pair of gauge ports.

Burned Out Air Conditioner Compressor

When the internal wing of the motor gets damaged, the compressor motor windings may be burned or shorted to the steel part of the motor. The windings may also burn and become disconnected. In this case, the air conditioner fails or does not start at all.

Avoid this problem by inspecting the electrical system of the air conditioner regularly.

Stuttering or On and Off Start Ups

This is commonly referred as hard starting. The compressor usually stutters and may not come on efficiently. If the problem is continuous, take a look at the fuse and the wiring. Replace the fuse if necessary and make repairs on the wires.

Problems with Motor

The air conditioner compressor may fail in case of an overload or if it over heats. This happens when there is an electrical fault within the appliance. To check for this problem, locate the motor and look at the reset button. If there is a fault, it pops out. Wait for it to cool down and push it back in. Always maintain the electrical system of the air conditioner in good condition to avoid this problem.
