Refrigerators have become an essential appliance in most households, helping us to store our food and drinks at the optimal temperature and keeping them fresh for longer periods. However, like any other machine, refrigerators can experience issues over time. One common problem is a faulty start relay, which can prevent the refrigerator from cooling properly or even cause it to stop working altogether. In this article, we will guide you on how to bypass a faulty start relay on a refrigerator, allowing you to troubleshoot and potentially fix the problem yourself.
Firstly, let’s understand what a start relay is and its role in the functioning of a refrigerator. The start relay is a small electrical component that controls the compressor, which is responsible for cooling the refrigerator. It helps to provide the necessary power boost to the compressor motor when it starts up. When the refrigerator is turned on, the start relay closes the electrical circuit, enabling the compressor to kick on and begin cooling.
Identifying a Faulty Start Relay
If your refrigerator fails to cool or does not turn on at all, there is a chance that the start relay might be faulty. However, it is essential to diagnose the issue accurately before attempting any repairs. Here are some signs that may indicate a faulty start relay:
1. Clicking Sound
When the compressor’s start relay is faulty, you may hear a clicking sound coming from the refrigerator. This clicking noise is an attempt by the relay to turn on the compressor but fails due to a malfunction.
2. Compressor Not Running
A faulty start relay often leads to a situation where the compressor does not start at all. The refrigerator may remain at room temperature, and there won’t be any cooling or freezing happening inside.
3. Intermittent Cooling
Sometimes, the refrigerator may experience intermittent cooling, where it cools for a while and then stops. This can occur due to a faulty start relay that fails to initiate the compressor consistently.
4. Warm Temperatures
If the refrigerator is not maintaining its cooling temperature, it could be a sign of a malfunctioning start relay. The compressor may not receive the necessary power to function correctly, resulting in warm temperatures inside the fridge.
Bypassing the Faulty Start Relay
Now that you have identified the signs of a faulty start relay, it’s time to learn how to bypass it. Bypassing the start relay can help you determine if the problem lies in the relay itself or elsewhere in the refrigerator’s electrical system. Follow these simple steps to bypass the start relay:
1. Safety Precautions
Before starting any repairs, ensure that the refrigerator is disconnected from the power source. Unplug it from the wall socket or turn off the circuit breaker that supplies power to the appliance. Safety should always be a top priority when working with electrical devices.
2. Locate the Start Relay
The start relay is usually located on the side, near the compressor at the back of the refrigerator. Consult the appliance’s manual or search online for the specific location based on your refrigerator’s make and model.
3. Access the Start Relay
To access the start relay, you may need to remove the protective cover or paneling at the rear of the refrigerator. Use a screwdriver or the appropriate tools to remove any screws or fasteners that hold the cover in place.
4. Identify the Start Relay Terminals
Once you have located the start relay, take a close look at its terminals. You will find three terminal connectors labeled “S,” “M,” and “C.” The “S” terminal stands for the start winding, the “M” terminal represents the main winding, and the “C” terminal stands for the common connection.
5. Disconnect the Wires
Carefully disconnect the wires connected to the start relay terminals. It is advisable to label or make a note of the wire placements to ensure proper reconnection later.
6. Join the Start and Main Terminals
To bypass the start relay, you need to create a direct connection between the “S” and “M” terminals. Use a short wire or a jumper wire to bridge these two terminals, effectively bypassing the start relay.
7. Secure the Connection
After connecting the “S” and “M” terminals, use electrical tape or suitable connectors to secure the wire connection. Ensure that the wire is firmly attached to prevent any accidental disconnections.
8. Reattach the Wires
Now, carefully reattach the wires to their respective terminals on the start relay. Double-check the wire placements based on the labeling or notes you made earlier, ensuring a correct and secure connection.
9. Test the Refrigerator
With the start relay bypassed and the wires reconnected, it’s time to plug in the refrigerator and switch it on. Observe if the compressor starts running and if the cooling function has been restored. If the refrigerator cools correctly, it indicates a faulty start relay that needs replacement.
When to Seek Professional Help
While bypassing a faulty start relay is a relatively simple process, it is vital to exercise caution. If you are not comfortable working with electrical components or if the refrigerator continues to display issues even after bypassing the start relay, it is advisable to seek professional help. Certified technicians have the expertise and knowledge to diagnose and repair complex refrigerator problems efficiently and safely.
In conclusion, a faulty start relay can lead to various refrigerator issues, including no cooling or intermittent cooling. By following the steps outlined in this article, you can bypass a faulty start relay and determine if it is the cause of the problem in your refrigerator. Remember to prioritize safety, unplug the appliance before starting any repairs, and consult a professional if you are uncertain or the problem persists. Maintaining and troubleshooting your refrigerator can help prolong its lifespan and ensure your food remains fresh and cool.
