Possible Causes

How to Fix / Troubleshooting

Safety first: Before opening the appliance, ensure the breaker is off and verify absence of voltage.

Basic checks:

  • Check the household breaker or fuse supplying the oven; reset or replace if necessary and see if it trips again.
  • Verify that the oven is correctly connected at the junction box or socket.

Internal checks:

  • Access the terminal block and confirm voltage is present at the oven when the breaker is on.
  • Locate any internal fuses on the control board or wiring; test and replace with identical type and rating if blown.
  • If fuses are intact and power is present at the board but the display remains dead, the control module power supply is likely defective and the board must be replaced.
