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.

Purchase

We purchased a circuit board for our furnace. It was delivered in 3 days. That was not the problem unfortunately, but they were very helpful in helping us diagnose the issue. I recommend this company very highly

Control board

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

Panel in good. I didn’t need the wiring harness that was recommended to install with the card. I’ll just eat it for $ 20.00.
