Suburban sf-35fq problems and fix

Long story short: buy a dinosaur electronics fans 50 plus pins mod board
Long story: I would turn on the thermostat it would click, the furnace would click, blower would not come on, i could not find anyone to come look at it ( im in a campground in n.w. indiana) decide to pull it out myself, check limit switch (normally closed) ok, check sail switch (normally open) ok and move it , it closes ok, put 12v to blower it spins, call a rv dealer order a new board , they get it in in 1 day which was good. Install the new suburban board from the dealer, and we are back in business furnace working fine. Go home for the weekend turn thermostat down to 50* for the weekend, get back monday after work and im out of propane. No big deal switch tanks, turn up thermostat, it clicks , furnace clicks, blower comes on but no heat?????? Go on the internet read other peoples problems, decide to change propane regulator ( mine trailer is a 2012 so i figure it could go bad), buy a furnace tune up kit from pdx, change burner, electrode, sail switch, limit switch, check resistance at gas valve and it is at 40 ohms like it is supposed to be from what i read other places. still no heat???!!! I read about the dinosaur boards and seen nothing bad about them so i order one. Install the new board and we are back in business, the heat is going!! Like everything else on these trailers they are made with cheapest stuff they can find. suburban's instructions are a joke for lining up the electrode, you cant see in there let alone shine a light in the back of the burner. On a side note the suburban board is made in china and the Dinosaur board was made in the u.s.a. Hope this helps somebody, and i hope the dinosaur board lasts longer than 3 days lol
