Signs Of Refrigerator Compressor Failure
Identifying early signs of a failing refrigerator compressor can save you time and money. Timely intervention can prevent further damage. Here, we’ll discuss the most common signs of compressor issues.
Consistent Operation Without Cooling
A refrigerator compressor running continuously but failing to cool is a red flag. Lack of cooling could indicate a faulty compressor. This may be due to internal wear or refrigerant issues.
Unusual Noises From The Fridge
Hearing strange noises from your refrigerator can be alarming. These noises might be humming, buzzing, or clicking sounds. They often point to compressor problems. Regular operation should be almost silent.
Compressor Overheating
An overheating compressor is a clear sign of trouble. Touch the compressor; if it’s too hot, it may be struggling to function. Overheating can lead to complete failure if not addressed.
Electrical Issues And Tripping Breakers
Frequent tripping of breakers or electrical problems can stem from the compressor. A failing compressor may draw more power, causing electrical issues. This can be dangerous and needs immediate attention.

Safety First: Preparing For Repairs
Repairing a refrigerator compressor involves several steps. Safety should always be your top priority. Understanding the necessary precautions ensures a smooth and risk-free repair process. Below, we discuss the essential safety measures to take before starting any repair work.
Unplugging The Refrigerator
The first and most important step is to unplug the refrigerator from the power outlet. This ensures no electrical current flows while you work. To avoid any accidental plug-in, you may even want to tape the plug to the refrigerator.
- Locate the power cord behind the refrigerator.
- Firmly pull the plug from the socket.
- Tape the plug to the back of the refrigerator.
Understanding Refrigerant Handling
Refrigerants are chemicals used in the cooling process. Mishandling them can be dangerous. Before starting, understand the type of refrigerant your refrigerator uses.
| Refrigerant Type | Common Usage | Safety Precautions |
|---|---|---|
| R-134a | Domestic refrigerators | Wear gloves and safety goggles |
| R-600a | Modern refrigerators | Avoid open flames |
Always work in a well-ventilated area. Use protective gear such as gloves and safety goggles.
Gathering Necessary Tools
Having the right tools is crucial for a successful repair. Here is a list of tools you will need:
- Screwdrivers (both flathead and Phillips)
- Wrenches
- Multimeter
- Refrigerant recovery machine
- Protective gloves
- Safety goggles
Ensure all tools are in good condition. Keep them within reach during the repair process.
By following these safety tips, you ensure a secure environment. This reduces the risk of injury while repairing your refrigerator compressor.
Diagnosing The Issue
Repairing a refrigerator compressor starts with an accurate diagnosis. Identifying the root cause of the problem ensures you apply the correct fix. Below, we break down the key steps in diagnosing a refrigerator compressor issue.
Inspecting For Visual Damage
Start by unplugging the refrigerator. Look closely at the compressor and its surroundings. Check for any visible signs of wear and tear. Look for the following:
- Cracks or leaks
- Burn marks
- Loose or frayed wires
If you see any of these signs, the compressor may need replacement.
Using A Multimeter To Test The Compressor
Use a multimeter to test the compressor’s electrical components. Follow these steps:
- Set the multimeter to the ohms setting.
- Locate the three terminals on the compressor.
- Test the resistance between each pair of terminals.
Record the readings. If the resistance is not within the manufacturer’s specified range, the compressor may be faulty.
Checking Amp Draw
Another critical step is to check the amp draw of the compressor. Use an amp meter for this task:
- Clamp the meter around one of the power wires.
- Check the reading while the compressor is running.
Compare the reading to the manufacturer’s specifications. A higher amp draw than specified can indicate a failing compressor.
Quick Fixes Before Replacement
Removing the compressor cover is an essential step in refrigerator repair. Accessing the compressor helps identify issues and perform repairs. Follow these steps to safely remove the compressor cover.
Locating The Cover
The compressor cover is usually at the back of the fridge. Look near the bottom area. It shields the compressor and other vital components.
Tools Needed For Removal
Gather the following tools before starting:
- Screwdriver: For removing screws.
- Wrench: To loosen any bolts.
- Flashlight: To see clearly in dark spaces.
- Gloves: To protect your hands.
Safety Precautions
Safety is crucial when working with electrical appliances. Here are some important tips:
- Unplug the refrigerator: Always disconnect from the power source.
- Wear gloves: Prevent injuries from sharp edges.
- Use a flashlight: Ensure you can see everything clearly.
- Have a buddy: It’s safer to work with someone else.
Following these steps ensures a safe and effective removal of the compressor cover. Stay safe and proceed with caution.
Removing The Compressor Cover
The start relay is a key component in your refrigerator’s compressor. If your fridge stops cooling, the start relay might be the issue. Replacing this small but vital part can restore your fridge’s function. Let’s dive into the process.
Identifying The Start Relay
Finding the start relay in your fridge is simple. It’s usually located near the compressor at the back of your fridge. The start relay is a small, box-like device attached to the compressor’s side.
To identify the start relay:
- Unplug your refrigerator.
- Move the fridge away from the wall.
- Locate the compressor at the back.
- Look for a small box attached to the compressor.
Step-by-step Replacement Process
Replacing the start relay is straightforward. Follow these steps carefully:
- Unplug the refrigerator to ensure safety.
- Remove the back panel to access the compressor.
- Locate the start relay on the side of the compressor.
- Carefully disconnect the relay from the compressor.
- Replace it with a new start relay of the same type.
- Reattach the back panel.
- Plug the refrigerator back in.
Testing The New Start Relay
After replacing the start relay, test it to ensure it’s working:
- Plug in the refrigerator.
- Listen for the compressor to start running.
- Check if the fridge starts cooling within an hour.
If the compressor runs smoothly and the fridge cools, the replacement was successful.
Remember, working with electrical components requires caution. Always prioritize safety.
