Possible Causes

Failed main power relay on PCB, Burnt track on control board, Loose supply wiring to control board, Internal control board fault

How to Fix / Troubleshooting

Danger: The control board carries live mains voltage. Disconnect power and only proceed if you are competent with electrical work.

  • 1. Verify supply to oven: Check the wall isolation switch and circuit breaker. Confirm correct voltage at the oven terminal block (by a qualified person only).
  • 2. Inspect terminal block and wiring: With power off, remove the rear cover and check the terminal block for heat damage or loose screws. Tighten connections and replace any burnt components.
  • 3. Examine control board: Remove the control panel to access the PCB. Look for burnt areas, cracked solder joints around relays, or swollen capacitors. If the heater relay is visibly damaged or the board is burnt, replacement is recommended.
  • 4. Functional test: After reassembly, restore power and select a heating function. Listen for relay clicks. If there is no relay activity and all wiring is sound, the control board is likely faulty.

Because of the shock risk, many users should leave board-level diagnosis and replacement to a professional.
