If your refrigerator unit is suddenly overheating and making a ticking sound, or if it’s not cooling, it normally should, but it sounds like it is operating, the refrigerator start relay could be broken. A refrigerator start relay is an apparatus usually located upon the compressor and aims to jump-start the compressor regularly.
The compressor in the refrigerator does not constantly run throughout the day. Instead, it switches on and off throughout the cooling process to keep the appliance at the right temperature setting. And since the start relay is the device that powers the refrigerator, the compressor won’t operate without it.
That being said, you may have to go around and bypass the start relay in your refrigerator. Bypassing the start relay entails bypassing the thermal overload, which may harm your equipment. Suppose you accidentally leave the start relay bypass running for an excessive amount of time. In that case, a bypass overload may occur, overheating your refrigerator and causing other components to malfunction and break.
Understand that a start relay bypass is just a short-term remedy, and consequently, you need to get your start relay replaced by an expert as soon as it can be done.
And with that, we at DaDongNY will walk you through the procedures you must take to ensure you can safely bypass the start relay within your refrigerator. So without further ado, get on board to discover how you can do it.
What Exactly Does A Start Relay On Your Refrigerator Do?
A start relay serves as an electrical switch that powers the unit’s compressor, which is responsible for generating the cold air around your refrigerator to keep your food and beverages chilled. It helps the compressor by alerting it when to turn on and off depending on the equipment’s need for cool air. The start relay preserves energy, maintains the effective operation of the refrigerator, and prevents overheating.
In other words, how does the start relay exactly work? When the refrigerator’s regulator recognizes an abnormally elevated temperature inside, it triggers the compressor. However, since the temperature regulator can’t handle the compressor’s electrical current, it activates the start relay. The relay then signals the compressor by delivering electricity to the compressor motor’s secondary winding through the overload device, supplying it with additional power to start spinning.
Symptoms Of A Defective Refrigerator Relay System
A compressor is a crucial piece of a refrigerator, and each one requires an operational start relay. If the relay system doesn’t work suddenly, you don’t need a refrigerator expert since several warning signs are surprisingly easy to identify. These are some examples:
- You’re Hearing Weird Clicking Sounds
The start relay on your refrigerator usually works silently but occasionally emits sound. Whenever it alerts the compressor to begin operating, it makes a clicking noise.
But here’s the thing, regardless of whether the relay system is broken, that clicking sound will keep happening. They are not going to cease even if the compressor has been turned off. The clicking noises will grow more and more frequent as the refrigerator continues to try to activate the compressor.
As soon as you hear those clicking noises, check your refrigerator closer. If the compressor is turned off, clicking noises should be heard every couple of minutes to five minutes.
- Refrigerator Contents Are Not Cooled
In order to figure out if your refrigerator’s relay system is broken, we highly advise you to open your refrigerator and conduct a quick test. Check all of the foods and beverages inside.
The contents should be chilled or frozen. If they aren’t, the compressor isn’t working properly. The issue at hand is probably linked to the start relay system.
- The “Shake And Rattle” Test
Do an actual check on the start relay by unplugging the device from the power supply. Find the compressor relay by opening the panel at the back of your refrigerator. Once you locate it, disconnect and shake the start relay. If you hear any rattling sounds inside the relay, something is loosened that has to be replaced.
In the event that there is no rattling, there could be something wrong with the compressor instead. Furthermore, you can also look for burned marks surrounding the relay terminals to determine whether it blew.
What Causes Relay System Damage
We went straight to the following indications of a faulty start relay, not knowing what would normally cause that problem. Therefore, here are two of the most prevalent causes of why the relay system could cause failure:
- Compressor Motor Failure
The compressor’s motor is designed to operate on an on-and-off cycle. They simply turn on when needed and turn off when not. The start relay and other components that make up your refrigerator might need to be fixed. As a result, this could cause the relay system to malfunction.
- Electrical Surge
Electrical surges are a common cause of a defective relay system, especially if you are living in residence with unreliable power. Frequent electrical surges might overwhelm the wire resistance and damage it, causing the start relay to malfunction.
As a result of the impedance that they create, these surges can lead the wires to get too hot. If the relay grows too hot, it may potentially fail. As a result, having a circuit breaker is the most effective way to protect yourself towards such harm.
How To Bypass The Refrigerator’s Relay System
What should you do when you’ve verified your refrigerator and discovered that it has signs of a faulty relay system? You can try to temporarily repair things yourself by following the instructions below.
To bypass the start relay on your refrigerator, you must arm yourself with a few essential tools. You probably already have them laying around your garage. They are as follows:
- Prepare The Working Tools
You can do DIY projects because you don’t need special tools. You only need a set of screwdrivers, some electric tape, and a pair of pliers.
- Request Help From A Friend
Since refrigerators are heavy, you should try to avoid moving them on your own. Ask for assistance and ask for their help to lift the refrigerator.
- Turn Off The Refrigerator Completely
You must first switch off the refrigerator before proceeding. Disconnect it from the wall’s outlet and relocate it to a secure spot where you will work.
- Open The Refrigerator Start Relay
Position the refrigerator so that you can easily access the bottom area while it is disconnected. Then, you should be able to locate a cover plate towards the bottom of your refrigerator. Remove it using a screwdriver.
Once you remove the cover plate, you will find a metal box on the right-hand side of your refrigerator. You’ll need to push or twist that metal box to gain access to the start relay system.
- Take Out The Start Relay
Next, take your flathead screwdriver and push into the space between the start relay and the casing. To remove the relay, you must further press it down. Once you’ve pulled the relay, start removing the metallic connectors connected to it.
- Change The Metal Connectors
Take your pliers and begin working on the metal connectors. Pull out all of the wires on each side using the pliers. Remove about a quarter-inch of the connectors.
- Restore The Connection Using Electrical Tape
Pick up a roll of electrical tape to secure the wires to the relay housing. Regardless of whether the relay system is faulty, this should enable the compressor to restart.
- Restore Your Refrigerator
You can now return the metal box and the cover plate to their original positions. Plug the refrigerator back in and see if the fixes have worked
Important Safety Precautions
- The most important thing to remember is that bypassing your refrigerator’s relay system is only a temporary solution. As a result, you should contact a specialist as soon as possible to assist you in repairing the relay.
