When a fridge begins to click every few minutes, it often points to a compressor relay problem. We know that these small but critical parts control how the compressor starts and runs, and when they fail, the noise is the first warning. Our team at JAY Appliances wants to break down what this sound means, why it happens, and what steps we can take to deal with it before the fridge stops cooling altogether.
What the Compressor Relay Actually Does
Every refrigerator uses a relay to help the compressor turn on with enough power. Without it, the compressor would struggle to start and eventually shut down. The relay acts like a switch that opens and closes quickly, giving the compressor the boost it needs. When the relay wears out, it clicks repeatedly as it tries but fails to maintain the electrical connection. We should pay attention to this clicking because it signals that the fridge might soon stop keeping food cold.
Why the Clicking Happens
Sometimes we hear the clicking because of simple wear. Relays handle constant starts and stops, and over time, their contacts weaken. Dust or grease around the relay can also make it overheat, which causes the internal parts to break down faster. Another cause is a compressor drawing too much current due to age or strain, forcing the relay to trip as a protective step. If left unchecked, this cycle continues until either the relay burns out or the compressor fails completely.
Signs the Problem is in the Relay
We can often tell the issue is with the relay and not another fridge component by looking at a few clues. The fridge may run for only a short time before shutting off again. The temperature inside starts to rise even though the unit is clearly trying to cool. In many cases, we can also notice a faint burning smell around the bottom back of the fridge. Hearing a steady click every few minutes combined with these signs makes it very likely that the relay is faulty.
How to Safely Check the Relay
Before doing anything, we should unplug the fridge for safety. The relay is usually attached to the side of the compressor and covered by a small plastic case. Once removed, it can be shaken gently. A rattling noise often confirms that the part is broken inside. For those with a multimeter, testing for continuity gives a clearer answer. If the relay shows an open circuit when it should be closed, replacement is the only solution. This is a straightforward check that we can do without complicated tools.
The Role of the Compressor in the Noise
While the relay is often the culprit, the compressor itself can also be part of the problem. If the compressor is failing, it may draw too much power and force the relay to trip repeatedly. We need to keep in mind that replacing a relay will not fix the issue if the compressor itself is worn out. Listening carefully to whether the compressor starts at all after each click can help us judge. A silent compressor even after the relay tries means the deeper problem lies in the compressor.
How to Prevent Relay Failures
Taking steps to reduce strain on the compressor helps extend relay life. Keeping the fridge coils clean allows heat to escape easily and lowers the workload. Making sure the fridge is not overloaded and has enough airflow inside also reduces compressor stress. Regular checks for dust and ensuring the fridge is level can prevent electrical and mechanical parts from wearing out too quickly. These small habits save us from facing repeated relay problems.
When to Replace and When to Repair
If the fridge is still fairly new and only the relay is at fault, replacement is often simple and cost effective. Relays are inexpensive and can be swapped in without special tools. However, if the fridge is older and the compressor is beginning to fail, it may not make sense to invest in just a relay. In these cases, it helps to weigh the cost of repair against replacement. Getting professional advice ensures that we make the right choice for the long term. For anyone in our area, fridge repair St Albert services can guide us through that decision with clear steps.
How Long a Fridge Can Run With a Clicking Relay
Running a fridge with a clicking relay is risky. The unit may keep cooling for a while, but each failed start adds more stress to the compressor. Over time, this can lead to total compressor failure, which is a much more expensive fix. Acting quickly when the sound first appears can save both money and frustration. We should treat the clicking as a clear sign to stop using the fridge until the issue is addressed.
Extra Insight on Power Surges and Relays
One detail that many people miss is that power surges can damage relays suddenly. A lightning strike or even brief outages in power supply can burn the contacts inside. Using a surge protector designed for appliances adds a layer of safety. This simple measure can help avoid unexpected failures that otherwise seem random. It is a step worth considering, especially for homes in areas with frequent electrical fluctuations.
How JAY Appliances Can Help
Our team understands how stressful it is when a fridge starts making strange sounds. We handle these issues daily and know when it is the relay and when the compressor needs attention. For reliable appliance repair in St Albert, we can diagnose the issue and offer the right solution. Ignoring a clicking sound almost always leads to bigger problems, so reaching out early is the best step.
Common Questions About Clicking Fridge Relays
Why does my fridge click every few minutes?
This usually happens when the compressor relay fails to stay closed. It clicks as it tries to send power but keeps resetting.
Can I replace a relay myself?
Yes, many relays can be swapped by following simple steps. However, we must always unplug the fridge and use caution when handling electrical parts.
Does a clicking relay always mean the compressor is fine?
Not always. Sometimes the compressor itself is damaged and causing the relay to trip. Testing both parts gives a full answer.
How much time do I have before food spoils if the relay fails?
A fridge without a working relay may hold temperature for a few hours if the doors stay closed. Beyond that, food safety becomes a concern.
Should I keep the fridge running until repair is done?
It is better to unplug the fridge if the clicking continues. Leaving it on risks burning out the compressor, making the problem worse.
