If your commercial cooler seems to run nonstop, it’s more than just an annoyance—it’s a sign that something may be wrong. A constantly running cooler wastes energy, shortens equipment life, and could even indicate a deeper problem that threatens your stored inventory.
At Buffo’s Refrigeration, we often see this issue in Nevada restaurants, grocery stores, and warehouses—especially during extreme temperature swings. Fortunately, the cause is often easy to identify and correct with the right maintenance or repair. Below are some of the most common reasons your cooler might be running all the time and what you can do about it.
Dirty Condenser Coils
When condenser coils get coated with dust, grease, or debris, they can’t release heat efficiently. As a result, your system has to work harder—and longer—to maintain the right temperature. Cleaning the coils regularly (usually once a month) improves efficiency and allows your cooler to cycle on and off properly. If your coils haven’t been cleaned in a while, this is a great first place to check.
Worn or Damaged Door Gaskets
If the door seals aren’t tight, warm air seeps in every time the cooler runs. The system then has to work harder to maintain temperature, which keeps it running constantly. Inspect the door gaskets for cracks, tears, or loose edges. Replacing damaged gaskets is inexpensive and can significantly improve performance while lowering your energy bills.
Improper Temperature Setting
Sometimes, the problem is as simple as the thermostat being set too low. When your cooler is set below recommended temperatures (typically around 35°F to 40°F for most applications), it runs longer than necessary. Check the thermostat setting and make sure it matches your product storage requirements. If your system still runs constantly after adjusting, it may need recalibration or service.
Blocked Airflow
Airflow plays a crucial role in your cooler’s efficiency. If boxes or food items block vents or fans, air can’t circulate properly, causing uneven temperatures and longer run times. Rearrange stored items to keep air pathways clear. If the evaporator fan motor is obstructed or malfunctioning, call a technician to inspect and repair it promptly.
Faulty Thermostat or Sensor
A broken thermostat or temperature sensor can give false readings, causing your cooler to think it’s warmer than it is. As a result, the compressor keeps running continuously. If your cooler temperature doesn’t match your thermometer reading, have a professional test and replace the thermostat or sensor if needed.
Refrigerant Leak or Low Charge
If your system has a refrigerant leak or the charge level is too low, it can’t cool efficiently. The cooler will run nonstop while struggling to reach the target temperature. Refrigerant handling requires certification and should always be done by a professional. Buffo’s Refrigeration can locate leaks, repair the system, and recharge refrigerant levels safely and correctly.
High Ambient Temperatures
In Nevada’s summer months, high kitchen or warehouse temperatures can also make your cooler work harder. Poor ventilation or proximity to cooking equipment adds heat load, forcing the compressor to stay on longer. If possible, improve airflow around the unit and ensure the condenser area stays cool and unobstructed.
When to Call a Professional
If your cooler continues to run constantly after checking the basics—like cleaning coils and sealing doors—it’s time to bring in an expert. Running continuously not only increases energy costs but also puts strain on the compressor, which can lead to premature failure.
