It fits perfectly and is working great so far. I used it on a SF35F Furnace for my sons trailer. It's cheaper than a dinosaur fan 50 board. We will see how long it lasts.

It's very simple to replace the old one and it got rid of the fan relay and has worked well since no problems

My current symptom was the furnace would ignite when cold, but as it warmed up the gas valves would turn off upon reignition. Checked absolutely everything on the furnace, complete tear down finding nothing wrong, including ignitor gap etc, which left the only one thing, was to replace the board. My assumption was that a component on the board gets hot and then fails. No signs of a loose or cold solder joints. After replacing with this board the furnace has been working in below freezing temps with no issues.

Board was missing 2 copper spacers. Spacers needed because of the plug (harness) they give the board space to plug in main harness.

Perfect replacement for my old board which I damaged. Same size, same connectors. Installed in my 2004 Suburban sf-30f furnace. I'm a happy camper !!
