E2 error on display, oven overheats or shuts off with fan running continuously

Safety first: Disconnect power and allow the oven to cool completely before inspection.

• Check ventilation: Ensure there is adequate space around the range as specified in the Hansa installation manual. Clear any obstructions from rear and side vents.
• Inspect cooling fan: Remove the rear cover to access the oven cooling fan (not the convection fan). Spin the fan blades by hand; they should move freely. If stiff or seized, replace the Hansa cooling fan motor.
• Test fan operation: Restore power briefly and start a low-temperature bake. The cooling fan should start after a short delay. If it does not, disconnect power and test the fan motor for continuity and supply voltage from the PCB (only if trained).
• Check safety thermostat: Locate the high-limit thermostat on the top or rear of the oven cavity. Test for continuity. If open and does not reset when cool, replace the Hansa high-limit safety thermostat.
• Control board relay: If the oven overheats rapidly, a stuck heating relay on the main PCB may be energizing elements continuously. Inspect the board for burnt spots and replace the main control board if necessary.

Warning: Overheating faults are a fire hazard. If you smell burning insulation or see smoke, disconnect power immediately and have the unit professionally inspected.
