No hot water at the campsite usually means one thing -- the ignition electrode has failed. The Atwood 20305 is a direct OEM-replacement post-style electrode spark probe engineered to restore reliable propane ignition to GCH6, G6A, and GH6 series Atwood water heaters. It drops in without modification and gets your hot water back without a service call.
Atwood's GC, G6, and GH series are among the most common 6-gallon propane water heaters found in travel trailers, fifth wheels, and Class C motorhomes. When the spark electrode wears out, cracks, or accumulates carbon buildup, the burner won't light and you lose hot water entirely. Swapping in a fresh OEM electrode is almost always the fix -- and the 20305 is the correct post-style probe for this family of heaters.
The post-style design positions the electrode tip at the correct gap relative to the burner head. Using the right electrode style matters: a mismatched probe can result in weak spark, misfires, or a lockout condition where the control board cuts gas after repeated failed ignition attempts.
Designed to the same specifications as the original factory electrode -- no drilling, no adapters, no trimming required.
Post-style electrode positions the spark tip at the factory-correct gap for consistent, reliable burner ignition on every startup.
Covers 11 confirmed GCH6, GC6A, G6A, and GH6 model variants spanning Atwood's most common 6-gallon water heater lineup.
Backed by Atwood's limited 2-year manufacturer warranty for peace of mind on the road or at the campsite.
The electrode spark probe is a wear item. It is the component responsible for generating the high-voltage spark that ignites the propane burner. If your Atwood water heater does any of the following, a failed electrode is a primary suspect:
