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.
