Fan runs but there is no heat; food remains uncooked.

Safety first: Unplug and cool the unit before working near the heater.

• Check for glow: In a darkened room, start a cook cycle and look through the top or side vents (without touching). If the element never glows red, the heater circuit is likely open.
• Inspect thermal fuse: Access the heater area and locate the thermal fuse in series with the element. Test for continuity; replace if open.
• Test heating element: Disconnect one lead and measure resistance. An open reading indicates a failed element that must be replaced.
• Check wiring and connectors: Tighten any loose spade connectors and replace burned terminals with high‑temperature rated parts.
• Control board: If the element and fuse are good but never receive power, the heater relay or triac on the main control board is likely defective and the board should be replaced.
