Display is very dim or unreadable, but charging still works.

Safety first: Turn off the breaker before removing the front cover.

• Step 1 – Adjust brightness: If available in the "Electrify Home" settings, increase display brightness and disable any aggressive power‑saving dimming.
• Step 2 – Inspect display window: Clean the outer lens with a soft cloth. Do not use solvents that could cloud the plastic.
• Step 3 – Reseat connectors: With power OFF, reseat the ribbon cable between the display and UI board.
• Step 4 – Replace UI board: If the backlight remains dim or off, replace the user interface/display board.
