Oven timer and display are blank; oven does not respond, but mains supply to the kitchen circuit is present.

Safety first: Turn off power at the breaker before opening any covers. Risk of electric shock.

Checks:

• Verify that the wall isolator switch (if fitted) is on.
• Remove the rear cover and inspect the mains terminal block for loose or burnt connections; tighten or replace as needed.
• Check for an internal fuse on or near the PCB; test and replace with the exact same type and rating if blown.
• If the fuse blows again immediately, there is a short circuit that must be located before further operation.
• If supply is present at the PCB but the display remains dead, the control board’s power supply is likely faulty and the board should be replaced.

Warning: Internal fuses blow for a reason; do not bypass or up-rate them.
