It's the board that runs the whole ignition sequence, from spark to flame. If your furnace fan spins but you never get heat, this is one of the first parts to check.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eWhen your Atwood furnace fan spins up but you never get heat, the ignition control board is one of the first things to check. This is the Dometic 34696, the genuine replacement ignition control circuit board for Atwood two-stage furnaces. It's the brain that runs the ignition sequence. It reads the call for heat, fires the spark, opens the gas, and confirms the flame. When that board goes bad, the furnace either won't light at all or lights and then drops out a few seconds later.\u003c\/p\u003e\n\u003cp\u003eThe 34696 fits the Atwood Hydro Flame 1522, 2334, and 2540 two-stage furnaces. These are the forced-air propane furnaces built into a lot of travel trailers, fifth wheels, and motorhomes. If your rig has one of those model numbers on the furnace label, this is the correct board. It's a two-stage unit, which means the furnace can run a low fire and a high fire depending on how hard the thermostat is calling for heat.\u003c\/p\u003e\n\u003cp\u003eThe two-stage design is one of the nicer features of these Atwood furnaces. On a mild fall night the furnace can loaf along on low fire, which is quieter and sips less propane. When a cold front rolls through, it steps up to high fire and actually keeps up. That staging is managed right here on the ignition control board. So a healthy board isn't just about getting the flame lit. It's about the furnace running the way the factory intended across the temperature range you actually camp in.\u003c\/p\u003e\n\u003cp\u003eSo how do you know it's the board and not something else? The classic pattern is a furnace that runs the blower, tries to light, and then locks out. Maybe you hear the spark clicking with no ignition, or it lights and then shuts down before the room warms up. Those are ignition-control faults. Before you swap the board, rule out the easy stuff first. A weak house battery is the number one cause of furnace ignition trouble on an RV. These boards want a healthy 12 volts to fire cleanly, and a battery sitting low under load will cause intermittent no-lights that look exactly like a dead board. Check your propane supply, make sure the tank valve is open and you've got gas at the appliance, and confirm the sail switch and limit switch are doing their job. If all of that checks out and you're still fighting ignition, the control board is the likely culprit.\u003c\/p\u003e\n\u003cp\u003eReplacing it is a job most handy RV owners can do in an afternoon. Kill the 12-volt power to the furnace and shut off the propane before you touch anything. The board mounts inside the furnace housing, and you transfer the wiring connectors over one at a time so nothing ends up in the wrong spot. Take a photo before you start. Match the connectors, seat them fully, and you're back in business. If you're not comfortable working around gas appliances, have an RV tech handle it. It's a quick job for them.\u003c\/p\u003e\n\u003cp\u003eThis is the genuine Dometic part, not a generic knockoff, so it lands as a true drop-in for the furnaces it covers. One thing worth knowing on some two-stage Atwood furnaces is that they use both a control module and a separate ignition board, and the parts can look similar. Pull your old board and match the part number before ordering so you get the right piece the first time. If your furnace label calls out the 1522, 2334, or 2540, the 34696 is the ignition control board you're after.\u003c\/p\u003e\n\u003cp\u003eIf you boondock or camp in the shoulder seasons, furnace reliability isn't a luxury. A furnace that won't light at 2 in the morning when it's 28 degrees outside is a miserable way to end a trip. That's why plenty of full-timers keep a spare ignition board in the rig. It's a small part that lives a hard life, cycling through ignition after ignition, and it's the kind of thing you want on hand before it strands you rather than after.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eGenuine Dometic 34696 ignition control circuit board, a true OEM drop-in for the furnaces it covers\u003c\/li\u003e\n  \u003cli\u003eFits Atwood Hydro Flame 1522, 2334, and 2540 two-stage furnaces\u003c\/li\u003e\n  \u003cli\u003eManages the full electronic ignition sequence: spark, gas valve, and flame confirmation\u003c\/li\u003e\n  \u003cli\u003eTwo-stage control runs low fire for quiet, propane-sipping operation and high fire for cold nights\u003c\/li\u003e\n  \u003cli\u003eDirect spark electronic ignition, so there's no standing pilot to relight\u003c\/li\u003e\n  \u003cli\u003eBolt-in replacement inside the furnace housing with plug-in wiring connectors\u003c\/li\u003e\n  \u003cli\u003eCommon fix for furnaces that spark but won't light, or light and then lock out\u003c\/li\u003e\n  \u003cli\u003eGenuine Dometic part number 34696, UPC 692931346960, for easy verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Dometic reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhich furnaces does the Dometic 34696 fit?\u003c\/summary\u003e\n    \u003cp\u003eIt's the ignition control board for the Atwood Hydro Flame 1522, 2334, and 2540 two-stage furnaces.
