If your Atwood or Dometic Hydro Flame furnace is failing to ignite or throwing an ignition lockout fault, a damaged or misaligned electrode bracket is a common culprit. This direct-replacement bracket restores proper electrode positioning so your furnace can fire reliably -- getting your rig warm without a service call.
The Atwood 34541 ignition electrode bracket is the factory-spec mounting component that holds the ignition electrode at the correct gap and angle relative to the burner assembly in 85 and 89 series Hydro Flame forced-air furnaces. When this bracket cracks, corrodes, or breaks, the electrode shifts out of position and ignition becomes erratic or fails entirely.
This part is also cross-listed under NBK part number 11455-2, a common aftermarket sourcing number used by RV service centers and parts distributors. Either number will return the same component.
Engineered to fit Atwood/Dometic 85 and 89 series Hydro Flame furnaces without modification or adapter hardware.
Holds the ignition electrode at the factory-specified position and gap to ensure consistent spark and proper burner light-off.
Listed as both Atwood 34541 and NBK 11455-2 -- cross-reference either number when ordering from service suppliers.
Weighs just 0.1 lb. Ships quickly and installs without special tools in most Hydro Flame furnace configurations.
In an Atwood Hydro Flame furnace, the ignition electrode is a spark-generating probe that sits near the burner orifice. The electrode bracket is the mounting arm that positions this probe at the precise angle and distance required for reliable ignition. If the bracket is cracked, bent, or burned away, the electrode can shift, widen the spark gap, or lose alignment with the gas stream -- all of which cause no-heat or lockout conditions.
Replacing the bracket is a straightforward repair that typically requires removing the furnace access panel and disconnecting the electrode lead wire. No brazing or burner work is needed in most cases.
Even small shifts in electrode position -- a few millimeters -- can cause intermittent ignition, delayed light-off, or repeated lockouts. A new bracket restores factory geometry and is often the fix when the electrode itself tests good but ignition is still unreliable.
This bracket is designed specifically for the Atwood/Dometic 85 series and 89 series Hydro Flame forced-air furnaces. These are common BTU-rated propane furnaces found in travel trailers, fifth wheels, motorhomes, and toy haulers manufactured over a wide range of model years. Common units in this family include the 8500-IV, 8516-IV, 8900-II, and related models.
Check the furnace data plate -- typically located on the furnace body inside the access compartment -- for the full model number. Confirm it falls within the 85 or 89 series before purchasing this bracket. Other Hydro Flame series use different electrode assemblies.
This listing covers the bracket only. The ignition electrode probe and high-voltage lead wire are separate components. Inspect those parts during the repair and order replacements separately if needed.
