MAIN PWB-K WP26X10073

This main control board is the central electronic unit that manages key air-conditioner functions, including temperature regulation, fan operation, and overall system performance. It replaces a failing board that may cause the unit to stop cooling, operate inconsistently, or become unresponsive to controls. Designed for select room air-conditioner models, it helps restore reliable cooling and proper function. Power should always be disconnected before installation, and work gloves are recommended for safety.
