Air fryer runs but does not heat; fan operates normally and no error code is shown.

Safety first: Unplug and allow the unit to cool completely before opening. Heating components are connected to mains voltage.

• Step 1 – Confirm no heat: Run the unit at maximum temperature for 5 minutes. If the interior and exhaust remain cool, the heater is not energizing.
• Step 2 – Check power supply: Verify the outlet voltage is stable and the cord is not damaged.
• Step 3 – Internal inspection (advanced): Remove the housing to access the heating element. Look for broken coils, burnt connectors, or discolored wiring.
• Step 4 – Thermal fuse check: Locate the thermal fuse near the heater. If it appears burnt or cracked, it may be open and must be replaced with the exact rating.
• Step 5 – Control board evaluation: If the element and fuse test good but there is still no heat, the heater relay or triac on the control board may have failed, requiring board replacement.
