Quick Answers
There are a few common reasons why a deep fryer may not be heating up properly:
- Faulty heating element – This is the most likely culprit. The heating element may be burned out or damaged and needs replacing.
- Thermostat issue – The thermostat regulates the temperature. If it’s not working properly, the fryer won’t heat up to the set temperature.
- Power supply problem – Check that the fryer is plugged in, the outlet is working, and the breaker hasn’t tripped.
- Broken temperature probe – This measures the oil temperature. If it’s faulty, the fryer won’t heat up.
- Clogged filter – A dirty filter can prevent the fryer from heating properly.
Troubleshooting Steps
If your deep fryer isn’t getting hot, follow these troubleshooting steps:
- Make sure the fryer is plugged in – Verify that the cord is fully plugged into the outlet. Try a different outlet to rule out a problem with the electrical supply.
- Check the power supply – Reset any tripped breakers or replace blown fuses. Try plugging in a different appliance to confirm the outlet is working.
- Check the temperature settings – Verify you have the thermostat set to the proper temperature for deep frying foods. Usually 350-375°F.
- Test the heating element – Unplug the fryer and allow the oil to cool completely. Remove the cover and check that the heating element is intact, with no broken wires. Use a multimeter to test its resistance.
- Replace the heating element – If the element is damaged or shows incorrect resistance values, it will need to be replaced. Match the wattage to the specifications for your fryer.
- Check the thermostat – The thermostat should click when the power is turned on. Use a multimeter to test it. If faulty, replace it.
- Inspect the temperature probe – Ensure the probe is clean and securely inserted. Check it with a thermometer. Replace it if inaccurate.
- Clean the filter – Unplug the unit and allow it to cool. Remove and clean the filter according to the manufacturer’s instructions to maintain proper oil flow.
When to Call a Professional
While many overheating issues can be fixed with basic troubleshooting, it’s best to call in a professional appliance repair technician if:
- You can’t diagnose the specific problem after troubleshooting
- The fryer requires disassembly beyond your comfort level
- Electrical testing is needed for the heating element or thermostat
- There are other malfunctions beyond heating problems
A technician has the tools, skills, and experience to accurately assess the issue and perform required repairs. They can also handle any warranty-related services.
Preventing Future Problems
You can minimize the likelihood of your deep fryer overheating or other failures by:
- Following the manufacturer’s instructions for usage and care
- Not overfilling the oil reservoir
- Keeping the fryer and filter clean
- Storing oil properly and replacing as needed
- Allowing sufficient cool down time between uses
- Not using extension cords or overloading circuits
- Performing periodic inspections of components
Proper maintenance and usage will maximize the lifespan of your deep fryer.
Replacing a Faulty Deep Fryer
If your fryer has repeated failures or is too expensive to repair, replacement is the best option. When selecting a new deep fryer, look for:

- High temperature capability (at least 375°F)
- Large oil capacity (4+ quarts)
- Durable stainless steel housing
- Digital controls and timer
- Safety features like auto shut-off
- Easy to clean with dishwasher-safe parts
