Morphy Richards oven display and controls are dead; no lights or response, but power is present at the wall.

Safety first: Turn off power at the mains before removing covers.

Steps:

• Check wall switch: Confirm the cooker switch is on and supplying power.
• Inspect terminal block: Remove rear cover and verify tight, undamaged connections.
• Internal fuse: Some Morphy Richards control boards have a small glass or ceramic fuse. Test and replace with the exact rating if blown.
• Mains filter: Test continuity through the mains filter module. Replace if open.
• Control board: If supply reaches the board but it remains dead, replace the electronic control board.
