Possible Causes
Loose display connector, Failing LED/LCD display module, Faulty display driver on main PCB, Voltage drop in control circuit
How to Fix / Troubleshooting
Safety first: Unplug the unit before accessing the control panel.
Steps to correct display issues:
- 1. Check power stability: Ensure the outlet provides stable power and that no heavy appliances share the same circuit causing dips.
- 2. Access display connections: Remove the control panel cover and locate the display module and its connector to the main PCB.
- 3. Reseat connectors: Unplug and firmly reconnect the display cable. Inspect for corrosion or bent pins.
- 4. Inspect display module: Look for cracks or signs of moisture inside the display. Replace the display module if physically damaged.
- 5. Replace main PCB if needed: If the display remains dim or segments missing with a known-good module, the LED driver or control circuit on the main PCB is likely faulty and the board should be replaced.
Warning: A failing display does not usually affect heating, but it can make safe operation difficult; avoid guessing settings.
