Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off the circuit breaker supplying the cooktop before inspecting any wiring. If you are not comfortable working with electrical systems, contact a licensed electrician.
- Verify supply voltage: Have a qualified person measure the line voltage at the cooktop junction box and compare it to the rating label on the Midea cooktop.
- Inspect terminal block:
- With power OFF, remove the rear or bottom access cover.
- Check that the power cord or supply wires are correctly landed on the L1, L2, N, and ground terminals per the installation diagram.
- Tighten any loose screws and look for signs of overheating or melted insulation.
- Reset after surge: If E3 appeared after a storm or outage, turn the breaker off for 5 minutes, then restore power and test.
Persistent E3 with correct voltage suggests damage to the power module or main PCB; professional service is recommended.
