Mc Enterprise 91365MC Electronic Spark Ignition Control Circuit Board

Description

Take full control of your RV’s hot water system with the Dometic (Atwood) 91365MC Integrated Control Board. This “Combo” board is the brain of your water heater, responsible for managing both the LP gas ignition cycle and the 120V AC electric heating element circuit.

Designed for Direct Spark Ignition (DSI) models, this board monitors the flame and ensures safety by shutting down gas flow if a flame isn’t detected. The “MC” version features a potted (sealed) design to protect the sensitive electronics from moisture, vibration, and the harsh environment of an RV exterior compartment.

Key Features

• Dual Functionality: Controls both the gas solenoid valve for propane heating and the relay for electric heating.

• Moisture Protection: Fully potted circuit board prevents corrosion and short circuits caused by humidity or condensation.

• Safety Timers: Automatically manages the ignition trial period and “lockout” mode to prevent unburned gas buildup.

• Direct OEM Fit: Engineered to mount perfectly in the existing plastic track of Atwood/Dometic water heaters.

Compatibility

Fits Atwood and Dometic 6 and 10-Gallon DSI Combo models, including:

• Models: GC6AA-10E, GC10A-4E, GCH10A-4E, G6A-8E, GH6-8E.

• Replaces: 93851, 93305, 91365, and AT93851.
