How to Fix / Troubleshooting
Safety first: Working on live electrical circuits is hazardous. If you are not trained, contact a licensed electrician.
- Check breaker: Ensure the double-pole breaker feeding the range is fully ON and not partially tripped. Reset if necessary.
- Verify voltage: Using a multimeter, confirm 240 VAC (or specified voltage) at the range receptacle and at the terminal block where the power cord connects to the oven.
- Inspect terminal block: With power OFF, check for burned or loose connections at the terminal block. Tighten screws and replace any damaged lugs or wiring.
- Internal wiring: If supply voltage is correct but LE persists, inspect the internal power filter board and harness for damage. Replace the filter or main control board if defective.
