I agree with the comments relative to sail switch and battery voltage. Our Suburban furnace was never reliable unless connected to shore power. Given that we did not boondock in cold weather we have just ignored this issue.
Hopefully this thread will help other in the future, would have been nice to have the OP chime in with either a little more info, or to share the cause if he already discovered the solution so others may Benifits down the road....but he hasn’t Returned since the initial post 10 days ago.
I just installed the same kit from PDXWholesale as N147JK in my Kid’s 2000 GTRV camper van and it worked out great. The Suburban Heater runs smooth, quieter and starts first time now.
