Refrigerators are essential appliances in our kitchens, ensuring that our food stays fresh and safe for consumption. At the heart of a refrigerator’s operation is the compressor, which is crucial in maintaining the right temperature inside the unit. But how do you know if the compressor is running? In this comprehensive article, we will guide you through the signs of a running compressor, troubleshooting steps, and when to call in the professionals for help.
Understanding the Role of the Compressor in Your Refrigerator
Before diving into how to determine whether your refrigerator’s compressor is functioning properly, it’s essential to understand what a compressor does. The compressor is often referred to as the “heart” of your refrigerator. It is responsible for circulating refrigerants throughout the cooling system, absorbing heat from the interior and expelling it outside. This process keeps the inside of your fridge at a regulated temperature.
How a Compressor Works
To better understand the compressor’s operation, here’s a simplified breakdown of its functions:
Compression of Refrigerants: The compressor takes in low-pressure refrigerant gas and compresses it into a high-pressure gas. This gas is then pumped through the condenser coils, releasing heat and turning into liquid refrigerant.
Cooling Cycle: The liquid refrigerant flows through the expansion valve and into the evaporator coils, where it absorbs heat from the refrigerator’s interior, thus cooling the space.
Cycle Repeats: The refrigerant then returns to the compressor to repeat the cycle, maintaining the desired temperature inside the unit.
Understanding how the compressor works allows you to diagnose potential problems related to refrigeration issues.
Signs That Your Refrigerator Compressor is Running
You may doubt whether your refrigerator compressor is running, especially if you notice changes in temperature or unusual sounds. Here are some signs that can indicate whether your compressor is functioning correctly:
1. Audible Noise from the Compressor
A running refrigerator compressor typically produces a rhythmic humming sound. If you can hear this sound, it’s a strong indication that the compressor is operational. However, keep in mind that some compressors may be quieter than others, so you might need to listen closely.
2. Temperature Stability
One of the primary functions of the compressor is to maintain a stable temperature inside the refrigerator. If the temperature feels consistent and your food and beverages are adequately chilled, it’s likely that the compressor is running efficiently.
3. Warm Compressor Area
Another way to check if your compressor is running is by feeling the temperature of the compressor unit located at the back of the refrigerator. If it feels warm or hot to the touch, this is typically a good sign that it is working. However, excessively hot temperatures may signify a problem that requires attention.
4. Frost Build-up or Ice Formation
If your refrigerator is exhibiting frost build-up or ice formation in unusual places (like the evaporator coils), this may indicate a malfunctioning compressor. In this case, it’s crucial to check whether the compressor is actively cooling.
Troubleshooting: How to Check if Your Refrigerator Compressor is Running
If you suspect that your refrigerator compressor might not be functioning properly, you can perform some simple diagnostics to confirm your suspicions.

- Open and close the refrigerator door to see if sounds change.
2. Monitor the Temperature
Use a thermometer to monitor the inside temperature of your refrigerator. If the temperature significantly drops below the safe threshold (approximately 35°F or 1.67°C), it may indicate that the compressor is running, but the food could still spoil due to fluctuating conditions.
Steps to Take:
- Place a thermometer in the main compartment of the fridge.
- Check the temperature reading after several hours.
3. Inspect the Condenser Coils
The condenser coils are responsible for dissipating heat generated by the compressor. Dust and dirt can accumulate on these coils, affecting efficiency. Therefore, it’s essential to check the condition of the coils.
Steps to Take:
- Unplug the refrigerator for safety.
- Locate the condenser coils, usually found at the back or bottom of the unit.
- Clean any dust build-up with a brush or vacuum.
4. Check the Relay and Overload Protector
The compressor relies on a relay and overload protector to start and run correctly. If these components are faulty, the compressor may not operate correctly.
Steps to Take:
- Find the relay on the back of the refrigerator, usually near the compressor.
- Inspect it for burnt or damaged components.
When to Call a Professional
Despite your best troubleshooting efforts, sometimes the issues might be beyond a simple fix. Here’s when it’s time to call in an expert:
Signs of Compressor Failure
If the compressor is not running at all after all your checks, it may need professional attention. Signs of total shutdown include:
- No Audible Noise: If there’s absolutely no humming sound, it could signify a failed compressor.
- Inconsistent Temperatures: If the temperatures fluctuate significantly despite your efforts to stabilize them, internal components may be failing.
Costs of Compressor Repair or Replacement
If you require professional help, understanding the costs associated with compressor repair or replacement is essential. Typically, you can expect to pay between $300 and $600 for replacement, depending on the make and model of your refrigerator. In some cases, the cost might outweigh the benefits of fixing an older unit.
Conclusion
Ensuring that your refrigerator compressor is running smoothly is vital for keeping your food fresh and your appliance efficient. Regular maintenance, timely troubleshooting, and understanding when to seek professional help can save you from major headaches and potential food spoilage in the long run.

As an important takeaway, always listen, monitor, and inspect your refrigerator regularly. You’ll not only ensure its longevity but also maintain a safe and healthy kitchen environment for you and your family.
How can I tell if my refrigerator compressor is running?
To determine if your refrigerator compressor is running, you can start by listening for any noise. Compressors typically emit a low humming or buzzing sound when they’re operational. If you hear this sound and the refrigerator is cooling properly, it’s a good indicator that the compressor is working. Additionally, you can place your hand on the back of the fridge; if it feels warm, this suggests that the compressor is functioning since it generates heat during the cooling process.
Another method is to monitor the temperature inside the refrigerator and freezer compartments. If the temperature is stable and remains cool, the compressor is likely maintaining the required cooling cycles. Conversely, if the temperatures begin to rise or fluctuate significantly, it may indicate that the compressor is not running effectively or is malfunctioning.
What should I do if my refrigerator compressor is not running?
If you suspect that your refrigerator compressor isn’t running, the first step is to check the power supply. Ensure that the refrigerator is plugged in, and inspect the circuit breaker for any tripped switches. Sometimes, a simple reset can restore power to the unit. Additionally, verify that the thermostat is set to the correct temperature. If the thermostat is incorrectly adjusted, that can prevent the compressor from engaging.
If the power supply is intact and the thermostat settings seem correct, it may be time to explore further. You can listen for clicking noises that may indicate a faulty relay or capacitor preventing the compressor from starting. In such cases, it’s advisable to consult a professional technician to diagnose the issue, as working on the compressor may require specialized tools and knowledge.
Can a refrigerator operate without a functioning compressor?
A refrigerator cannot effectively operate without a functioning compressor. The compressor is responsible for circulating refrigerant throughout the system, which is essential for absorbing heat from inside the fridge and releasing it outside.
