Atwood31501 OEM RV Hydro Flame Furnace Ignition Board - Printed Circuit PC Control Board

Good quality, packaging, fits perfectly and works good. Easy replacement.

OEM exact replacement for Atwood Model 8940-III-DCLP, 2006 3905 Weekend Warrior. My heater went from working perfectly to not turning on at all every other time for two days, then stopped working completely on day 3. No fan or heat at all. Replaced the thermostat which did nothing but was starting to show its age as it would not keep the perfect temperature like it did for many years, so I am glad I changed the thermostat. Replacing this motherboard on my unit was incredibly simple. Easy access to the motherboard from outside and very easy removal and quick replacement. My furnace fired right up and ran like brand new at the exact temperature I set it too. I highly recommend it!

Tried 2 other boards that were cheaper and both failed to work my igniter in my Atwood camper furnace. This was more $ but works perfectly.

Let's start with the cover plate for easy access to the heart of your furnace. They work and then... they don't work trying to keep water/rain out of the access area. It's guaranteed (for us) that rain gains entry with every heavy directional rain. Thus, even though our board is slightly suspended, it can still sit in water at times. Usually, if the furnace doesn't kick-on during a rain, it's due to the board getting wet though the furnace exhaust port. Long story short one day after a rain the furnace ran fine until it until it attempted to turn off. Click-click-click-click-click could be heard in the furnace area forcing me to run out and turn of the reset switch to stop it. After drying and trying, I knew the board was toast. So, I ordered this to replace the bad one and viola! The board is built well just like it's OEM predecessor and its still doing a fantastic job. But, if I can't keep it dry, failure will result and I can't blame the board for that. Fast delivery, protective packaging and dependable. I'm definitely going to be a return customer if I should need this part again.

Old circuit board got wet when silicone seal shrunk on outside wall around edge of furnace. Water found its way in and pooled up on a plastic shelf that my old board was sitting on. Being wet and shirting circuits out and Corrosion took its toll on the board causing all kinds of issues from 10 second run, then flame would go off, then 10 second run, then off till it finally locked out. To eventually it would never ignite. Relocated new board with zip ties in case water finds its way in again and siliconed the outer edge again. This board plugged right in and my furnace worked perfectly like day one. Saved the day!! And saved tons of money compared to dealer getting part.Furnace is Atwood model AFMD35131 (30k BTU) and is in a 2017 Montana High Country fifth wheel

The board was exactly like the original and fixed my problem.

I have an older Atwood furnace and the circuit board STB. Researched and verified that this would work with my furnace and it does, flawlessly. My only complaint is the adapter plug for the board, it's flimsy when installed and when you plug the cable it. It's secure enough, but again this is a moving unit, so we'll see if it comes loose over time.

easy to install for a DIY. had our RV heater working in minutes.

Worked great and easy to install

Thanks
