Whirlpool Insufficient Heating / Underheating

Air fryer takes much longer than normal to cook food; never seems to reach set temperature.

Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Partially failed heating element (hot spots, reduced output), Weak mains voltage, Failing temperature sensor reading too high, Control board limiting heater output

How to Fix / Troubleshooting

Safety first: Disconnect power and cool the unit.

Performance checks:

Verify the outlet voltage is within specification using a multimeter.
Run the air fryer empty at maximum temperature for 10 minutes and feel for strong hot airflow at the exhaust. Weak heat suggests element or control issues.

Component checks:

Inspect the heating element for discoloration or partial burn-through. Replace if damaged.
Test the temperature sensor; if it reads lower resistance than expected (indicating a higher temperature than actual), the control will underheat. Replace the sensor if out of range.
If sensor and element are good, the control board may be misregulating power and should be replaced.
