Description

This is a replacement switch-mode power supply (SMPS) board assembly that restores reliable low-voltage power to the appliance control electronics. Replacing a failed unit helps return stable operation to lights, displays, and control circuits. What it does:

• Converts incoming mains power into the low-voltage DC rails used by the control board and displays.
• Provides regulated power to sensors, user interface modules, and communication circuits.
• Commonly replaced when the appliance has no display, intermittent resets, or does not power on.
• May clear issues caused by power surges, blown onboard components, or failed voltage regulation.

What's included:

• One power supply board assembly (SMPS module).

Install notes:

• Disconnect all power before starting; risk of electric shock remains until capacitors discharge.
• Inspect connectors and wiring for heat damage; replace damaged harnesses before installing the new board.
• Handle the board by the edges and avoid touching components to prevent ESD damage.
