Dometic / Atwood 34109 Ignition Control Circuit Board

Replacement For Atwood XT 2-Stage RV Furnaces

Part Number: 34109
Product Type: Ignition Control Circuit Board
Manufacturer: Dometic / Atwood

Product Overview

The Dometic / Atwood 34109 Ignition Control Circuit Board is a replacement control module designed for Atwood HydroFlame XT two-stage RV furnaces. This board manages ignition timing, gas valve operation, and blower motor control to ensure safe and reliable furnace operation.

When the original control board fails, symptoms can include the furnace failing to ignite, blower motor running without heat, or inconsistent heating cycles. Replacing the ignition control board restores proper ignition sequencing and burner control for two-stage furnace systems.

This circuit board is designed specifically for Atwood XT-series two-stage furnaces, ensuring proper communication between the thermostat, blower motor, gas valve, and ignition components.
