MC 93849MC Water Heater Element Power Relay for Atwood Dometic RV

The MC 93849MC is an aftermarket replacement power relay designed for Atwood and Dometic RV water heaters. This essential component controls the switching circuit that supplies power to the electric heating element in your water heater system.

How It Works:

When the electric mode switch is activated, the control board sends DC voltage through the yellow wire to energize this relay. The 12-volt DC input activates the relay, which then switches 110V AC power to the heating element, allowing your water heater to operate in electric mode.

Key Features:

• Operates on 12V DC input, switches 110V AC output
• Direct replacement for Atwood/Dometic OEM part 93849
• Designed for RV and marine water heater applications
• Compatible with multiple Atwood water heater models
• Made in the USA

Compatible Models:

• GCH6A-10E
• GC6AA-10E
• GC10A-4E
• GCH10A-4E

Troubleshooting Tips:

If you have no power passing through the relay, check breakers and fuses in your distribution panel. Confirm both AC and DC power are present at the relay. If AC power reaches the element but no heat is produced, the element itself may need replacement.
