To tell if a refrigerator compressor is bad, first listen for the "click-then-nothing" sound, check if the fridge struggles to cool, and feel the compressor to see if it’s excessively hot. You can definitively diagnose it by testing the electrical pins with a multimeter or checking the start relay.
Testing a refrigerator compressor involves checking three electrical pins for shorts to ground and evaluating the motor windings to ensure they are electrically sound. If your compressor is clicking on and off or not running at all, this step-by-step diagnostic process will help isolate the issue.
If your fridge is making loud clicking noises, constantly running without cooling, or failing to turn on entirely, the compressor may be bad. You can confirm a failing compressor by checking the electrical pins with a multimeter or observing the motor's physical behavior.
To reset a refrigerator compressor, perform a hard power reset: unplug the fridge (or flip its specific circuit breaker) for 5 to 10 minutes. This allows the compressor’s internal thermal overload switch to cool, clears error codes from the control board, and resets any compressor timing locks.
Whether replacing a refrigerator compressor is worth it depends mostly on the age of your fridge, your warranty status, and the replacement cost.
The most common cause of refrigerator compressor failure is overheating. Overheating places extreme thermal stress on the motor and internal moving parts, ultimately leading to mechanical seizure or motor burnout.
Bottom-freezer refrigerators should be repaired within seven years and considered for replacement after that. Top-freezer refrigerators should be repaired within three years, considered for repair within three to six years, and replaced if older than seven years.
Yes, unplugging a refrigerator will reset the compressor, as well as the main control board and sensors. This simple power cycle forces the system to reboot, which often clears minor software glitches and allows the compressor's internal thermal overload switch to reset.
The compressor, coils and control board are the most expensive repairs. Your fridge's brand, model and size, plus your location, will impact repair costs. If your refrigerator is more than 6 years old and it will cost you more than half its original price to repair it, consider replacing it instead.
The reset button is almost always located on the electric motor itself—usually on the side or back near the terminal box. It typically sticks out as a small rubber-covered or exposed black/red button, sometimes labeled "Circuit Breaker".
Reset Power
When a refrigerator compressor fails, it stops circulating the refrigerant required to absorb and remove heat. Consequently, the appliance loses its ability to cool. The internal temperature will rise, causing food to spoil rapidly, and you will likely hear strange clicking or humming noises from the back of the unit.
If your fridge is making loud clicking noises, constantly running without cooling, or failing to turn on entirely, the compressor may be bad. You can confirm a failing compressor by checking the electrical pins with a multimeter or observing the motor's physical behavior.
A bad air conditioning compressor struggles to pressurize and circulate refrigerant. The most common symptoms include warm or lukewarm air from the vents, loud grinding or squealing noises when the AC is on, the compressor clutch failing to engage, and repeated tripping of your home's circuit breaker or car's AC fuse.
Your Refrigerator Is Always Running
While it's normal for your refrigerator to cycle on and off throughout the day, a refrigerator running non-stop might indicate an issue with the compressor.
The Amish keep food cold using a variety of off-grid methods, tailored to the strictness of their local church district. Common practices include:
Which refrigerator brand is most reliable? All three of the appliance experts we spoke to for this roundup said Whirlpool and LG were the most reliable refrigerator brands due to their durability, reliability and ease of repairs. Samsung and GE were also mentioned by our experts as high-quality fridges.
There is no single "number one" refrigerator brand, as the best option depends on your priorities. However, industry experts and consumer testing currently highlight three top brands:
No, there is generally no physical reset button on a standard refrigerator compressor. Instead, the compressor relies on a built-in "overload protector" designed to automatically cut power if it overheats or draws too much current, and will reset itself once the motor cools down.
To reset a refrigerator, unplug it for 5 to 10 minutes. This duration ensures the internal capacitors fully discharge, allowing the control board to reboot and clearing out temporary electronic glitches or sensor errors.
To quickly get your fridge cooling again, start by checking the simplest fixes:
Compressor Replacement
As you might expect, the compressor is one of the most important parts of the refrigerator so it is one of the most expensive. While you can purchase the part yourself, it's not recommended that you try to replace it on your own.
Discard refrigerated perishable food such as meat, poultry, fish, soft cheeses, milk, eggs, leftovers, and deli items after 4 hours without power or 2 hours after the temperature rises above 41 °F. At any time, discard spoiled, moldy food and anything that does not look or smell right.
Watch for warning signs like food spoiling prematurely, clicking or buzzing noises, continuous motor running, or excessive frost/condensation. Older units often cost more to repair than replace.
