Frequently Asked Questions
How do I know if my circuit breaker needs replacement?
Common signs include: furnace won't start at all, furnace starts but immediately shuts off, breaker feels hot to the touch, visible burn marks or melting on the breaker, or the breaker won't stay in the reset position. If your furnace has intermittent operation or you hear clicking sounds, the circuit breaker may be failing.
Can I use a different amp rating circuit breaker?
No, always use the exact 15 amp rating specified for your Atwood furnace. Using a higher amp breaker eliminates critical overload protection and could cause furnace damage or fire hazard. A lower amp breaker will trip unnecessarily during normal operation. The 15 amp rating is engineered specifically for your furnace's electrical draw.
Where is the circuit breaker located on my Atwood furnace?
The circuit breaker is typically mounted on the furnace control board or near the power supply connections inside the furnace housing. You'll need to remove the furnace cover panel to access it. The breaker usually has a red reset button and is connected with wire terminals. Always disconnect shore power and battery before servicing.
Is this breaker automatic or manual reset?
This is an automatic reset breaker, meaning it will trip and cut power when it detects an overload, then can be manually reset by pressing the button once the fault condition is resolved. This design protects your furnace while allowing you to restore operation after addressing the underlying issue that caused the trip.
