A refrigerator should cycle on and off throughout the day, but a few weeks ago I noticed mine running non-stop. The motor hummed continuously, and while it kept food cold, I worried about energy bills and possible damage. At first, I assumed the compressor was failing. But after checking the manual, I found out that a fridge running constantly is a common problem, often linked to airflow, temperature settings, or simple maintenance issues.
Common Reasons Why a Fridge Runs All the Time-
Temperature set too low – The fridge works harder than necessary.
-
Dirty condenser coils – Dust buildup prevents heat from escaping.
-
Door not sealing properly – Cold air leaks, forcing the fridge to overwork.
-
Frequent door openings – Letting warm air in too often keeps it running.
-
Overstuffed shelves – Air circulation becomes blocked inside.
The manual recommends setting the fridge to around 3–5°C (37–41°F). Mine was set to the coldest option, which explained why it never shut off.
2. Clean the Condenser CoilsAccording to the manual, coils at the back or bottom should be cleaned twice a year. I vacuumed off a thick layer of dust, and the motor began cycling normally again.
3. Inspect the Door SealThe manual notes that worn or dirty seals cause cold air leaks. I wiped mine clean and checked with a paper strip — if it slides out easily, the seal needs replacement.
4. Limit Door OpeningsThe manual suggests avoiding unnecessary openings. I made a habit of grabbing everything I need at once, and the fridge stopped overworking.
5. Rearrange Shelves for AirflowFinally, the manual explains that blocked vents can confuse the temperature sensor. After moving items away from the back wall, cooling became more balanced.
My ExperienceAt first, I thought my fridge was nearing the end of its life. But by following the manual — cleaning the coils, adjusting the temperature, and checking the seals — I solved the problem without repairs. Now, the fridge cycles normally, uses less electricity, and stays at the right temperature.
FAQWhy does my fridge run constantly?
– Most often because of low settings, dirty coils, or leaking seals.
Can I fix this problem myself?
– Yes, by following the manual: clean coils, adjust the thermostat, and check door seals.
When should I call a technician?
– If the fridge still runs continuously after maintenance, the compressor or thermostat may need repair.
