How to Fix / Troubleshooting

Safety first: Unplug the microwave before inspection.

Steps:

  • Power reset: Disconnect power for 10–15 minutes, then reconnect. This can clear some temporary firmware faults.
  • Check outlet and power quality: Plug the microwave directly into a properly grounded wall outlet. Avoid extension cords or power strips that may cause voltage drops.
  • Observe behavior: After reset, test multiple buttons and functions. If the display still shows E10 or is unresponsive, the control board is likely faulty.

Technician repair:

  • Remove the control panel and inspect the main control PCB for burn marks or damaged components.
  • Verify all harness connections are secure.
  • Replace the main control PCB with the correct Hisense part number if necessary.
