It’s important to note that a fault in the defrost timer can also cause other issues, such as the entire refrigerator not cooling properly or experiencing temperature fluctuations.
To determine if the defrost timer is the reason behind the ticking sound, inspect the component for visible damage or physical defects. If there are no signs of damage, but you suspect the defrost timer is faulty, you can test it using a multimeter or seek professional assistance.
Other possible causes of a ticking refrigerator include problems with the evaporator fan motor or damaged compressor start relay. It’s important to identify the exact source of the ticking noise before addressing the issue.
Possible Cause of a Ticking Refrigerator: Damaged Compressor Start Relay
If your refrigerator is emitting a ticking noise, a damaged compressor start relay may be to blame. This component is responsible for receiving the electrical signal that starts the compressor motor. When it is damaged or malfunctioning, it can cause a ticking sound that is similar to a clock ticking.
You may also notice that your refrigerator is not cooling properly or that it is not turning on at all. These are signs that the compressor start relay is not functioning correctly.
Replacing a damaged compressor start relay is a relatively simple and inexpensive fix. First, unplug the refrigerator and locate the relay, which is typically located near the compressor in the rear of the refrigerator. Remove the old relay and carefully install the new one, making sure that it is properly connected and secured.
If you are not comfortable replacing the component yourself, consult a professional technician to ensure that the repair is done correctly.
