I recently decided to repair my NT 30sp furnace with little luck. Yesterday I logged on and began reading through the threads and relized that the problem with my furnace wasn't talked about. Problem being that my fan would come on but no heat. Plenty of LP and 13.2 volts from the batteries.
As I read throught the the threads everyone gave me ideas on how to troubleshoot the problem.
I took the heater out of its housing simply by reomving four screws inside and one out of the exhaust hole on the outside of my 270. I put the heater on the counter inside the RV and began first by testing the limit switch, then the sail switch, then the valves, then the time delay switch, then the electrode, all were good with individual testing. I found that when I put power to the module board that is when nothing wated to respond. Lone and behold that was the problem. Next problem was cost. In Missoula MT there are only a hand full of dealers with a parts house. I called around first it was $189, then $184, Last but not least $113 at Rangtish Brothers. Also $7.04 for a new electrode.
Installed new module board and now we're heating things up again!!
The end of my experiance is a simple thank you to everyone who has had problems with their heaters
if not for you I would have had a large repair bill.
Basically a plug and play replacement.
