Saburban SF-30F troubleshoot

[@ricksters310]

My blower only works when I connect both blue wires together, what could be my issue? I also just purchased a new thermostat

I’m having the same problem. I bought a new board and it the relay wouldn’t click. Do you know which board you installed?

[@frankredlinerv]

I used the universal board from dinosaur electronics

I used a standard trailer plug kit to extend the wires a bit and make removing and replacing the unit easier.
Simple plug and play. I hate you have to remove these units from the inside. Piss poor design.
