How to Troubleshoot a Constantly Running Refrigerator

A constantly running refrigerator can be caused by a number of things. The problem should be attended to promptly, because constant operation takes a toll on the appliance's working parts and wastes electricity. Discovering the root of the problem requires systematic troubleshooting to rule out various common causes. Troubleshooting can eliminate costly repairs if the problem is simple to correct, and can prevent extensive damage by alerting you that it's time to call the repairman.

Instructions

- 1
  Unplug the refrigerator and clean the condenser coils by vacuuming away dust and debris with a brush attachment. The coils may be located behind the refrigerator or beneath it, depending upon the model. If located at the bottom of the appliance, you will likely have to snap off the protective grill before vacuuming.

  Examine the door seals for damage; a damaged seal may allow cold air to escape rapidly and cause the refrigerator to run more than normal.
- 3
  Turn the refrigerator off and disconnect it from its power source. Manually defrost the refrigerator and freezer to remove ice buildup that may interfere with its operation. Line the interior of the appliance with absorbent towels to catch water that melts as the refrigerator defrosts. Replace the food, plug the refrigerator back in and turn the power back on. The appliance may run continuously for several hours after defrosting.

  Consult a repairman if the refrigerator continues to run constantly for more than 24 hours after defrosting.
