If your Atwood Hydro Flame furnace is failing to ignite, cycling off unexpectedly, or throwing erratic behavior traced to the ignition board, the PC board edge adapter is a common culprit. NBK Parts 11455-1 is a direct replacement that restores the critical electrical connection between the printed circuit board and its edge connectors -- getting your furnace back online without replacing the entire control board.
The PC board edge adapter is the interface between the Atwood 31501 ignition board's PCB traces and the wiring harness connectors in your furnace. Over time, vibration from road travel, heat cycling, and corrosion degrade this connection, causing intermittent ignition failures or complete no-heat conditions. This NBK Parts adapter is built to OEM specifications and installs without modification.
NBK Parts specializes in hard-to-find RV appliance repair components. The 11455-1 is a precise fit for the Atwood 31501 ignition board and is not a universal generic -- it matches the original connector pitch and terminal configuration for a secure, vibration-resistant connection.
Engineered to match the Atwood 31501 ignition board's original edge connector spec. No splicing, no adapters, no modifications required.
Built to withstand the heat cycling and vibration common in RV furnace compartments. Materials selected for long service life in high-temperature proximity.
A degraded edge adapter is a frequent cause of intermittent ignition and furnace lockout. This replacement brings connections back to spec.
NBK Parts backs this component with a limited 2-year warranty, providing confidence in the repair for the long haul.
The edge adapter physically seats onto the card-edge of the Atwood 31501 PCB and provides the socket interface for the furnace wiring harness plug. When this adapter develops corrosion, loose contact, or physical damage, the furnace control board cannot receive or send reliable signals -- resulting in ignition failures, short cycling, or a furnace that simply won't start.
Replacing just this adapter is a cost-effective repair step before committing to a full ignition board replacement. Many technicians and experienced DIY RVers address this component first when troubleshooting Atwood Hydro Flame furnace electrical issues.
The 11455-1 edge adapter lets you restore furnace function without replacing the entire ignition board. A targeted fix for a specific failure point -- less waste, less expense, faster repair.
This adapter is designed specifically for use with:
If you are unsure whether your furnace uses the 31501 ignition board, check the board itself for the part number printed on the PCB or referenced on the furnace data label inside the access panel.
Open the furnace access panel and locate the control board. The Atwood part number -- typically 31501 -- is printed directly on the board. If your board carries a different number, confirm compatibility before ordering.
Replacing the PC board edge adapter is a straightforward repair for anyone comfortable with basic RV appliance work:
While the furnace access panel is open, inspect adjacent wiring harness connectors for corrosion and heat damage. Clean contacts with an electrical contact cleaner before reconnecting. This simple step can prevent repeat service calls on the same furnace.
NBK Parts focuses on replacement components for RV appliances that OEM channels no longer stock readily. For Atwood and Hydro Flame furnace owners, sourcing a specific PCB adapter through a dealership can mean long lead times or an unwanted full-board replacement. NBK Parts stocks these specific components so you can complete a targeted repair on your schedule.
If your Hydro Flame furnace has been experiencing ignition problems, it may also be worth inspecting the sail switch, limit switch, and gas valve wiring while the access panel is open. Addressing multiple wear points in one service visit saves time on the road.
