How to Fix / Troubleshooting
Safety: Unplug the unit before accessing the control area.
- Reset: Unplug for 10 minutes and reconnect. If E-92 returns, proceed to inspection.
- Check connections: Remove the control panel and inspect the wiring harness between the main PCB and the display board. Reseat connectors.
- Look for damage: Examine the display board for burn marks or bulging components. If present, the board must be replaced.
- Replace display board: If reseating connections does not help, replace the display PCB assembly. This is typically a plug-in replacement but should be done carefully to avoid damaging ribbon cables.
