Hi,
I just joined this group, so I hope I do this right.
I have a '90 Westy, owned since new, with 178K miles. Two years ago I picked up a '88 Westy with 54K miles. The '88 had a Trumatic E1800 heater and a second propane tank underneath, both of which I transferred to the '90. The heater (an older, no longer made model from 1989) worked fine for a year and half, then became intermittent and now works not at all. Well, the igniter works and the flame starts, but after few seconds the unit shuts down, with the red LED on. I have been unable to get any support from Truma in Germany or the UK (this heater was never sold in NA).
I have tried almost everything. It is getting gas, I have tried it on both tanks, on a just-filled tank, different temperatures and altitudes. Tried connecting it directly to the regulator, by-passing the copper lines. It has the correct voltage, I have two batteries.
I have disassembled it many times, cleaned & oiled the motor, cleaned the fans (there are two running off the same motor, one for combustion air, one for warm air). I have cleaned the spark electrodes and the flame rectification electrode. They are in good condition.
I have checked all other electrical connections and the two fuses, even changing them. So, it seems to come down to some thing on the controller board not getting the msg "everything OK down here, keep running". I have visually checked the board for bad joints, obvious burned components and checked & cleaned the edge connectors.
I live in a small town in AZ. There is a small RV repair place but I am not sure he would be able to test the board, and anyway, Truma did say parts are no longer available. So, any help would be appreciated. I saw the earlier posts from member Windchill, that he got a new E2400 from the UK, but saw no follow-ups. Anyone else able to buy a new Trumatic directly from Europe?
Thanks,
Jerry
