Frequently Asked Questions
How do I know if my furnace circuit breaker needs replacement?
Signs include: furnace won't start, breaker trips repeatedly even after reset, breaker won't stay reset, or visible damage to the breaker housing. If your breaker trips frequently, investigate the underlying electrical issue before replacing.
Can I use a standard automotive circuit breaker instead?
No. This Dometic breaker is specifically designed for RV furnace applications with precise amperage ratings and temperature tolerances. Using incorrect breakers can result in inadequate protection or nuisance tripping.
What causes a furnace circuit breaker to trip?
Common causes include: motor bearing failure drawing excessive current, shorted wiring, control board issues, or blower wheel obstruction. If the breaker trips immediately after reset, there's likely a short circuit that needs repair.
How do I reset this circuit breaker?
Locate the breaker (usually near the furnace control board), press the reset button firmly until it clicks. If it trips again immediately, disconnect power and investigate for electrical faults before attempting further resets.
