Refrigerator Running Constantly
Beyond repair — restoring peak performance. This guide will help you understand the causes, check for simple solutions, and know when professional service is needed.
Common Symptoms
You may be experiencing one or more of these symptoms:
- Compressor never cycles off
- Higher than normal energy bills
- Refrigerator feels warm on outside
- Food properly cold despite constant running
- Unusual humming or vibration
Possible Causes
Our specialized approach ensures our experience, these are the most common causes ranked by likelihood:
Dirty condenser coils
Most LikelyCoils can't release heat efficiently, so compressor runs longer.
Faulty door seal
Most LikelyAir leakage forces constant cooling to maintain temperature.
High ambient temperature
Most LikelyArizona summer heat makes compressors work harder.
Thermostat set too cold
PossibleExtremely cold settings require more run time.
Defrost system failure
PossibleFrost buildup on coils reduces efficiency.
Refrigerant leak
Less CommonLow refrigerant reduces cooling capacity.
What You Can Check
Before calling for service, try these safe checks that may resolve the issue:
- 1
Check thermostat setting
Refrigerator at 37°F and freezer at 0°F are optimal - colder settings cause constant running.
- 2
Feel door seal temperature
If warm air is felt around the door, the seal needs attention.
- 3
Measure room temperature
If ambient temperature exceeds 90°F, increased running is normal.
- 4
Clean condenser coils
Dirty coils are the most common cause of constant running.
- 5
Check for frost buildup
Excessive frost in freezer indicates defrost system problems.
When to Call a Professional
Contact a certified technician if:
- Constant running continues after cleaning coils and checking settings
- Energy bills have significantly increased
- Refrigerator can't maintain temperature despite running constantly
- You hear unusual sounds from the compressor
- The compressor is extremely hot
Prevention Tips
Help prevent this issue from occurring in the future:
- Clean condenser coils quarterly in Arizona climate
- Avoid placing refrigerator in direct sunlight or near heat sources
- Ensure adequate ventilation around the unit
- Replace worn door seals promptly
- Schedule annual professional maintenance
Arizona Climate Consideration
Arizona's extreme heat, monsoon humidity, and hard water can contribute to this and other appliance issues. Our technicians understand these local factors and can provide recommendations specific to desert climate conditions. Regular maintenance is especially important in Arizona to prevent premature component wear.
