Even though it doesn't look like the one being replaced, the description stated it was for my furnace. I installed it, and it works perfectly. Couldn't be more happy!

This board worked well. Unfortunately, the Surburban NT 34 heater is a piece of junk. Have replaced so many parts, now it's time to just find a different heat source.

Furnace would not throw heat, only cold air. Troubleshooting problem pointed me to the circuit board - thermostat would start furnace cycle, no gas smelled and no ignition. Tested gas solenoid to be good - speculated problem to be circuit board. Ordered part, and it fixed the problem.

I thought my module was burnt out. The wires were just switched and it won't work when the polarity is off. Now I have two.

Our NT20SEQ furnace in our 2016 HW296 went out, of course when it was in the 30's...brrrrrAfter reading forums, I replaced the igniter, then the sail switch, then the control board. The control board was the culprit.Once the thermostat was tuned on, our furnace fan would run, then the propane switch would open (click), but the igniter was not sparking (no clicks), thus no ignition. The cycle would repeat 3 times before the fan would shut off.If you have propane in your tank, and your fan runs, you should smell propane at the exhaust (outside the camper, at the rear of the furnace) when the propane switch opens (click. If if you do, then you know propane is making it into the furnace, and that your sail switch is giving the OK to send fuel. At this point I would inspect your igniter, because it's the easiest part to examine. If you don't suspect the igniter, go for the control board.This board was a little larger, and the 2 power terminals were on the side rather than the top. Everything was plug and play though, except I needed to tap a screw hole for a 2nd screw since only one would line up to the 4 furnace existing screw holes. There were only 2 screws holding the original.Hope this helps!
