In this guide, Publican Anker gives the most accurate signs so that you can easily recognize the fault of the refrigerator and promptly repair it. In addition, Publican Anker also offers some remedies that not everyone knows. Importantly, these measures are based on expert judgment.
Signs and Symptoms of a Bad Relay on a Refrigerator
The refrigerant is compressed by the refrigerator compressor relay, which turns it into liquid and heats it. The refrigerator compressor loses heat through the condenser coils at the back. It then pumps the refrigerant through an extension chamber, where it quickly evaporates and chills to make the fridge cold air.
The actual compressor does not run continuously, and it only runs during cooling cycles. It needs assistance starting up every time the cooling cycle starts. This is the responsibility of the refrigerator compressor. You should replace the PTC plugs is bad if you notice signs of a bad starter, such as a refrigerator that isn’t cooling.
Refrigerator Not Cooling
If the compressor doesn’t startup, it is an obvious sign that the overload is not working. The compressor circuit will hum intermittently throughout the day. If the compressor doesn’t make this sound and the positive temperature coefficient in the fresh food compartment or freezer starts to rise, there is a good possibility that the PTC isn’t working properly.
Clicking Relay Noise
The compressor turns on when the overload activates it. This click is audible. This click occurs regardless of whether the compressor turns on.
The start relay will attempt to start winding again if the compressor doesn’t turn on. This usually happens in intervals of between two and five minutes. The PTC plugs are likely to fail if the clicking continues.
The Shake and Rattle Test
The best way to test the relay is to inspect it physically. The compressor’s relay is in the same compartment as the compressor. It is plugged into its back. Open the compartment and disconnect the power supply to the fridge. Give the compressor a good shake by unplugging the missing relay.
If the relay is rattling, it is likely that the part has failed and must be replaced. It may be a problem with your compressor if it isn’t rattling but still appears in good condition. Repairs to compressors are more expensive and can be very serious.
Replacing the Start Relay
You may better call a professional to repair your refrigerator if you aren’t an expert DIYer. If you decide to attempt this task, make sure you unplug the refrigerator completely from the outlet.
You may need assistance in removing the refrigerator from the wall. Refer to your user manual for the location and wiring diagram of the overload refrigerator.
It is easy to replace the starter is bad in your refrigerator. Unplug the defective component and install a new one. Just remove the compartment cover and disconnect the power supply.
Take the relay from its socket and replace it with a similar type. The problem should be solved, and your refrigerator will normally work again.
How to Fix Relay on Refrigerator?
The refrigerator’s relay jump-starts its compressor. The refrigerator’s relay can be damaged, which could cause the compressor to stop working and cause the interior to freeze.
The compressor is an important component of the refrigeration system. It must have functioning refrigerator contacts that is bad to function. A damaged refrigerator could be why your refrigerator power cord is heating up or making strange clicking sounds.
Step 1 – Remove the Relay for Testing
The missing relay can become damaged if the compressor warms up and a loud click is heard. To have the refrigerator start relay box checked, it must be taken out of the system. Be sure to unplug it first before removing the refrigerator contacts from the system.
The relay can be found at the bottom of your fridge. To expose the compressor, remove the cover at the back. A small box is located near the compressor with wires sticking out.
Older units often have a wire-wound coil easily visible because they have a cooper wound around a plunger. Modern units have solid-state, which require special equipment to check. These relays are more susceptible to frying than the wire-wound.
Step 2 – Inspect the Relay for Problems
It may be necessary to replace terminals on relays with severe corrosion. Some relays can be restored to their original functionality by simply cleaning them. Use a metal cleaner to remove the corrosion and to put it back. You can then test to see if the problem has been solved. If the relay does not continue to work, it could have failed.
Step 3 – Check for Bad Relays
You can check whether or not the relay is functioning properly by using a variety of methods. You can easily test the solid-state relays by taking them out of the compressor and shaking them. If the relay makes a rattling noise, it is likely to be burned out. It is best to have it checked by professionals.
An ohmmeter can be used to check wire-wound. The relay usually has three terminals: two of the usual terminals marked M and S and one slip-on terminal marked L.
Place the tester’s probes at the two female terminals S, and M to check for continuity. Flip the relay upside down with the probe still touching the terminals. The tester should now hear a click and read infinity.
You can repeat the steps with the probes touching terminals S or L. The same procedure is repeated with the probes attached to terminal M or L.
The reading should remain at zero, even if the relay is bad turned over. If it is not, replace it. You should ensure that you purchase the same relay at the supply store.
How to Test a Refrigerator Start Relay
It’s worth taking the time to understand how to test a refrigerator’s relay. This will help you identify any issues, fix them, save you money, and ultimately, you can save money on buying a new one.
This is not an easy task, but it’s possible with some focus and determination. This is how to test the refrigerator’s relay.
Step 1 – Disconnect from the Electrical Source
By turning off the circuit breaker or unplugging your fridge, you can turn off electricity from the refrigerator. This safety precaution should be taken whenever you work with electricity or electrically powered equipment.
If you are testing a refrigerator’s relay, it is important to shut off power to prevent electric shock. Also, the compressor motor windings may start relay during testing, altering your results.
Step 2 – Find the Relay
Locate the fridge compressor first. You will need to take the refrigerator off the wall. The compressor motor is usually located at the bottom of the fridge. It would help if you were careful when moving the fridge to damage your kitchen flooring. Ceramic flooring is not easy to damage, but it shouldn’t take long for linoleum to be permanently damaged.
To overload protector the fridge, place cardboard on the ground. After the fridge has been pulled out, look for a large cylindrical-shaped object with copper tubings attached. You just found the compressor. Look to the right for a box that has wires sticking out. This box contains the relay.
Step 3 – Access the Relay
If necessary, remove the cover from the box and loosen it using a screwdriver. In most cases, you won’t need to use a screwdriver as the cover is held in place by tension clips or retaining clips that can be manually removed. The overload protector and the relay are contained within the box.
The relay is the largest component. While a wire-wound is easy to test, a solid-state will require professional testing. Use needle-nose pliers to remove the wire wound.
Step 4 – Test the Relay
Locate the “S”, “M,” and “L” plug-type terminals as well as the slip-on terminal. Place the relay on the counter, table, or floor so that the “S” terminal and the “M” terminal face down. Place the multi-tester on the floor, counter or table so that the “S” and the “M” terminals face down.
The tester should be set to zero ohms. If the start relay is working, flip it over, and the reading will change to “infinity” after a clicking sound. Place one probe from the “S” terminal to the L terminal.
If the unit is functioning properly, the tester should read “zero”. You will need to replace the unit if it isn’t.

What does a fridge starter relay do?
The start relay for hard-start kits connects and disengages the starting capacitor terminals of the electrolytic motor into the motor’s start winding circuit. Either a potential or current relay, automatically disengages the start capacitor once the motor has reached two-thirds of its operating speed.

How do you bypass the start relay on a refrigerator?
First, remove the metal connector that connects it to the start system. Next, use pliers and a pair of scissors to cut some wire on each side (no more than 1/4 inch). Connect both ends of the wire to the start relay housing using electrical tape. This will allow the circuit to close completely.
What causes a refrigerator relay to go bad?
Relays protect refrigerators from damage caused by electricity. A relay can overload protector or fail due to an electrical surge. The resistance of the wire can cause the current to be impeded, and the wires may heat up and melt. An electrical surge can cause this.
How do you test a start relay?
A digital multimeter is all that’s needed to test a start relay. Once the start has been removed from its fuse box, you can use the multimeter to measure DC voltage. Next, check to ensure there are 12 volts at the 85 position of the fuse box (or wherever the start relay is bad).
