Safety: Isolate the oven from the mains supply before removing any panels.

Confirm fan operation: Turn the oven to a fan setting and listen. If the fan runs but there is no heat, the fan element is the prime suspect.
Inspect the fan element: Remove oven shelves and the internal rear panel to expose the circular fan element. Look for breaks, bulges, or burn marks.
Test continuity: From the rear of the cooker, access the fan element terminals. Disconnect the wires and measure resistance with a multimeter. A reading of open circuit means the element has failed and must be replaced.
Check terminals and wiring: Ensure the spade connectors are tight and not heat-damaged. Replace any discoloured or brittle wiring with high-temperature cable rated for ovens.
Reassemble and test: After fitting a new Belling-compatible fan element, refit panels, restore power, and test on a low temperature first to confirm correct operation.

Fan oven not heating but fan runs normally; food remains uncooked.
