Dometic Atwood 33780 Furnace Circuit Breaker – 7 AMP

The Dometic™ Atwood 33780 Hydro Flame Furnace Circuit Breaker is a 7-amp pop-up style circuit breaker designed to protect the electrical system in many Atwood RV furnaces. This breaker automatically interrupts electrical power if the circuit becomes overloaded, helping prevent damage to the furnace wiring, blower motor, and control components.

If your RV furnace suddenly loses power, shuts down during operation, or fails to start despite having power available, the circuit breaker may have tripped or failed and require replacement.

FAQ

What does a furnace circuit breaker do?

The circuit breaker protects the furnace by shutting off electrical power if the circuit draws more current than it should, preventing damage to electrical components.

What is a pop-up circuit breaker?

A pop-up breaker automatically pops outward when the circuit trips, making it easy to see that the breaker has been triggered and allowing it to be reset.

What causes an RV furnace breaker to trip?

Common causes include blower motor issues, wiring problems, or electrical overload within the furnace system.

Can a weak breaker cause furnace issues?

Yes. A worn breaker may cause intermittent power loss, nuisance trips, or prevent the furnace from running consistently.
