Description

• Provides power and signal control for the front display and LEDs.
• Relays button/touch inputs to the main control so the appliance responds to user commands.
• Can cause a blank or unlit display, no response from front controls, or intermittent/incorrect error indications when failing.
• Works with the main control board to maintain proper display behavior and status indicators.

What's included: One display power control board assembly. Install notes:

• Disconnect power (unplug the appliance or shut off circuit breaker) before starting work.
• Use anti-static precautions and handle the board by its edges to avoid damage.
• Make sure all connectors seat fully and routing is correct before restoring power.
