Reasonably easy to remove and install and works well. Good longevity will improve it’s rating but I just got it.

5 Worked as intended
Posted by C.C. RV Repair on Nov 24th 2024
For the model I repaired furnace SF30FQ I had to move the cables to I had more slack to reach the side of the board, the OEM product in this model has the 4 pin connector on the "bottom" of the control board. Other than that slight modification the board worked exactly as it should have. Happy Customer.

Furnace would not heat. After a quick test with unit out of the trailer found the original board not working. Ordered the new one and it was very easy and quick to replace. Tested again and furnace lit and heated up right away
