Description

The Dometic 3313190.021 is an LCD Relay Control Board designed for Dometic Brisk Air and Penguin RV air conditioner systems. It functions as the command center for the AC, managing temperature settings, fan speed, and cooling cycles.

This is a genuine OEM replacement part. It is compatible with rooftop AC systems and operates on 12V DC. If your RV's AC is not responding to the thermostat or cycling erratically, this control board may be the solution.
