How to Fix / Troubleshooting

Safety first: This involves live mains wiring. If you are not experienced with electrical work, contact a qualified electrician or technician.

  • Verify supply voltage: Confirm that the oven is connected to the correct voltage as specified on the Hisense rating plate (often 220–240 V AC). Incorrect supply can trigger E8.
  • Inspect terminal block: With power OFF, remove the rear cover to access the mains terminal block. Check for loose screws, burnt insulation, or discoloration. Tighten connections and replace any burnt components.
  • Check power cord: Inspect the cord for cuts, kinks, or burn marks. Replace if damaged.
  • Control board inspection: Look for swollen capacitors or burnt components on the main control board’s power supply section. If found, replace the board.
