The oven does not heat at all, no error code is displayed, and the fan and light may or may not work.

Safety: Turn off power at the isolator and breaker. Verify with a voltage tester that the cooker is de-energized before opening panels.

• Check basics: Confirm the wall isolator is on and the breaker has not tripped. Reset it if necessary.
• Test other functions: See if the oven light or clock works. If nothing works, suspect a power supply or main fuse issue. If lights work but no heat, suspect elements or controls.
• Inspect thermal cut-out: Access the rear of the cooker and locate the thermal cut-out on top of the oven cavity. Reset it if it has a button; replace it if it has failed open.
• Check elements: Test the main oven and grill elements for continuity. Replace any elements that show an open circuit.
• Selector switch: If elements are good, test the function selector switch for continuity in each position. Replace the switch if contacts are not closing as specified.
