Dometic / Atwood 34696 Ignition Control Circuit Board

Replacement For Atwood 2-Stage RV Furnaces

Part Number: 34696
Product Type: Ignition Control Circuit Board
Furnace Type: Two-Stage Electronic Ignition Furnaces
Manufacturer: Dometic / Atwood

Product Overview

The Dometic / Atwood 34696 Ignition Control Circuit Board is a replacement control module designed for Atwood HydroFlame two-stage RV furnaces. This electronic ignition board manages the furnace ignition sequence, including spark ignition, blower timing, and gas valve control to ensure safe and reliable operation.

When the ignition board fails, the furnace may run the blower without igniting, fail to start heating cycles, or shut down prematurely. Replacing the control board restores proper furnace ignition sequencing and burner operation.

This board is specifically engineered for Atwood XT and other two-stage furnace systems, providing a direct replacement for the factory-installed control module.
