A power reset may not resolve the issue, indicating a deeper electronic failure that requires further diagnosis.

Common Symptoms:

  • Oven displays E-84 and stops normal operation
  • Error persists after power cycling
  • May occur during or shortly after attempting to heat

Possible Causes

  • Communication failure between control PCB and other internal boards (main/inverter/relay sub board) (medium)
  • Faulty control PCB (main control board) (medium)
  • Damaged wiring harness or loose connectors between internal boards (medium)

How to Fix Error E-84
