The Dometic 30322 is a 7-amp circuit breaker designed specifically for Atwood Hydro Flame furnaces. This critical safety component protects your furnace's electrical system from overload and short circuits, automatically cutting power when amperage exceeds safe levels. If your Hydro Flame furnace isn't firing up or keeps shutting down unexpectedly, a failed circuit breaker is often the culprit.

Frequently Asked Questions
How do I know if my circuit breaker has failed?
Common symptoms include: furnace won't start at all, furnace starts then immediately shuts off, breaker button is popped out or won't stay reset, or intermittent furnace operation. If the breaker trips repeatedly after resetting, there may be an underlying electrical issue that needs diagnosis.
Can I use a different amperage circuit breaker?
No. Always use the exact amperage rating specified by Dometic/Atwood for your furnace model. Using a higher-rated breaker defeats the safety protection and could damage expensive furnace components. Using a lower-rated breaker will cause nuisance tripping.
Where is the circuit breaker located on my Hydro Flame furnace?
The circuit breaker is typically mounted on the furnace control board assembly or on the furnace housing near the electrical connections. You'll need to access the furnace compartment (usually from inside a cabinet or exterior access door) to locate and replace it.
Will replacing the circuit breaker fix my furnace problem?
If the breaker itself has failed (won't reset, shows visible damage, or tests bad with a multimeter), replacing it will restore furnace operation. However, if the breaker trips immediately after replacement, you likely have a short circuit, bad motor, or other electrical fault that requires further troubleshooting.
