How to Fix / Troubleshooting
Danger: This involves live 240V circuits. If you are not qualified, contact a licensed electrician.
- Verify supply: At the home electrical panel, ensure the range is on a double-pole breaker of the correct amperage (typically 40–50A).
- Inspect terminal block: With power off at the breaker, remove the rear cover over the power terminal block. Check for loose screws, burnt wires, or melted insulation. Tighten connections to manufacturer torque specs.
- Check cord configuration: Ensure the power cord and jumper strap are configured correctly for 3-wire or 4-wire installations per the installation manual.
- Measure voltage (qualified persons only): With power on, verify 240V between L1 and L2 and 120V from each leg to neutral/ground. Correct any supply issues.
