Air fryer powers on but does not heat; fan runs normally and timer counts down.

Safety first: Unplug the air fryer and let it cool. Heating circuits carry dangerous voltages.

Basic checks:

• Set the temperature to maximum and start a cycle. After 3–5 minutes, check if any heat is felt at the exhaust. If not, the heater is not energizing.

Internal inspection (advanced):

• Remove the top cover to access the heating element and associated wiring.
• Inspect the element for visible breaks or burn spots.
• Test continuity across the heater terminals with a multimeter. Infinite resistance indicates a failed element.
• Locate the thermal fuse in series with the heater and test for continuity. Replace if open with a high-temperature fuse of the same rating.
• Check the heater relay on the control board for burnt contacts or cracked solder joints.

Replace any failed component (heating element, thermal fuse, or control board) with a compatible T-fal part.
