A commercial fryer is the workhorse of any fast-paced kitchen. Whether you're using a pressure fryer for chicken or an open fryer for French fries and snacks, your entire workflow can be disrupted when something goes wrong. At Minewe, we believe that understanding the most common fryer problems—and how to solve them quickly—can save time, reduce costs, and keep your kitchen equipment performing at its best.
Here are the top fryer issues our customers encounter, and our quick tips to help you fix them.
1. Fryer Not Heating Up Properly
Possible Causes:
-
Faulty thermostat or temperature sensor
-
Heating element failure
-
Power or gas supply issues
Quick Fix:
-
Check power or gas connection first.
-
Reset the high-limit safety switch.
-
Test the thermostat for accuracy and replace if needed.
-
For gas fryers, ensure the pilot light is working properly.
Tip: Regular thermostat calibration prevents uneven cooking and energy waste.
2. Oil Temperature Fluctuates or Overheats
Possible Causes:
-
Malfunctioning thermostat
-
Damaged high-limit switch
-
Dirty temperature probes
Quick Fix:
-
Clean the temperature sensors regularly.
-
Inspect and replace any faulty switches.
-
Use a thermometer to double-check oil temperature during operation.
High oil temperature can degrade oil faster and increase fire risk—don’t ignore it.
3. Oil Foaming or Bubbling Too Much
Possible Causes:
-
Dirty oil or old oil
-
Moisture in the oil
-
Overloaded baskets
-
Soap or detergent residue from cleaning
Quick Fix:
-
Replace the oil immediately.
-
Dry food thoroughly before frying.
-
Ensure fryer tank is rinsed well after cleaning.
Use oil filters daily to maintain oil quality and reduce waste.
4. Fryer Won’t Turn On
Possible Causes:
-
Electrical supply problem
-
Blown fuse or tripped breaker
-
Faulty power switch or internal wiring issue
Quick Fix:
-
Confirm outlet and voltage supply match the fryer’s requirement.
-
Replace fuses or reset the breaker.
-
If the fryer still won’t start, call a qualified technician.
Always check the user manual before opening the fryer casing.
5. Maintaining Built-in Filtration System=Quick Solutions
Issue 1. Overload Protection Triggered, Oil Pump Inactive
Possible Cause: Blocked oil pump pipelines or clogged pump head.
Quick Fix:
- Press the red reset button on the oil pump.
- Manually clean pipelines and pump head to clear obstructions.
Issue 2. Faulty Micro Switch Contact, Oil Pump Failure
Possible Cause: Loose contact in the filter valve’s micro switch.
Quick Fix::
- Check the micro switch alignment.
- Adjust the metal tab on the micro switch.
- Reactivate the filter valve – an audible click confirms proper function.
Critical Prevention Tip: Always Use Filter Ppaer!
6. Unusual Noises or Vibrations
Possible Causes:
-
Loose parts or fryer basket
-
Fan or pump failure (in advanced models)
-
Oil boiling too aggressively
Quick Fix:
-
Check for loose screws or misaligned baskets.
-
Inspect internal fans or oil pumps (if applicable).
-
Lower oil temperature slightly and avoid overloading.
