Dometic DSI Control Board & AFL Igniter - Furnace Ignition System - Part# 30621
The Dometic 30621 DSI Control Board with AFL Igniter is a critical replacement component for Dometic RV furnaces, controlling the direct spark ignition system that lights your furnace burner. This OEM control board manages the ignition sequence, flame sensing, and safety shutoff functions to ensure reliable furnace operation in cold weather. If your furnace won't ignite, cycles repeatedly, or shows error codes, this control board and igniter assembly is often the solution.
Designed as a direct replacement for failed or malfunctioning DSI boards in Dometic furnace models, this genuine part restores proper ignition timing and flame detection. The integrated AFL (Automatic Flame Lock) igniter provides the spark needed to light the gas burner while the control board monitors flame presence for safe operation.
Key Features
- Complete DSI Control System: Integrated control board and AFL igniter in one replacement assembly for simplified installation
- Direct Spark Ignition Technology: Eliminates the need for pilot lights, providing reliable ignition on demand
- Flame Sensing Safety: Monitors burner flame and automatically shuts off gas flow if flame is not detected
- OEM Dometic Quality: Genuine replacement part engineered to exact factory specifications for reliable performance
- Diagnostic LED Indicators: Built-in status lights help troubleshoot ignition issues and error codes
- Weather-Resistant Design: Built to withstand temperature extremes and vibration in RV environments

Frequently Asked Questions
Q: How do I know if my DSI control board has failed?
A: Common symptoms include furnace not igniting after multiple attempts, continuous clicking without ignition, error codes on your thermostat, or the furnace blower running but no heat. If the igniter sparks but the burner doesn't light and stay lit, the control board's flame sensing circuit may have failed.
Q: Does this part include both the control board and igniter?
A: Yes, the Dometic 30621 is a complete assembly that includes both the DSI control board and the AFL igniter electrode. This integrated design ensures proper electrical matching between components and simplifies the replacement process.
Q: Can I install this control board myself?
A: Installation requires basic electrical knowledge and comfort working with 12V DC systems and LP gas appliances. You'll need to disconnect power, remove the old board, transfer wire connections to the new board, and test operation. If you're not comfortable working with gas appliances, professional installation is recommended for safety.
Q: Will this fix a furnace that blows cold air?
A: If your furnace blower runs but produces no heat, and you hear clicking sounds indicating ignition attempts, this control board may solve the problem. However, cold air can also result from gas supply issues, blocked burners, or limit switch problems. Verify that the igniter is sparking before replacing the control board.
