Possible Causes

Household supply voltage above rated range, Incorrect wiring (240 V applied to 120 V model), Loose or damaged power cord connection at terminal block, Power surge or unstable mains

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.
