I now have a problem that has occurred in two separate trailers in the same type of situation, with no apparent cause or remedy.
The problem is this. After several days camping in cold temperatures with the furnace cycling on and off as needed, the furnace would simply refuse to relight. Of course this happens in the middle of the night each time.
I have tried to "reset" the system by turning off the furnace at the thermostat, disconnecting and reconnecting the power (both at the batteries and to shore power) and disconnecting and reconnecting the propane. When the furnace was turned back on, the blower would run for 15 seconds or so, but there was no indication that the DSI would fire to light the burner. The blower would then turn off.
Each time this would happen (twice with the old trailer and once with the CR), the furnace would eventually restart. This last time it started after I removed the front of the furnace and checked for any loose wiring connections. No issues were found but the furnace miraculously started again.
When this happened with the old trailer, I brought it in to the service department, but they could not recreate the problem. They did end up replacing the thermostat as this was all that they could think of. Of course we sold this trailer before being in a position where the problem could present itself again.
I am concerned now that the same issue has happened with the new CR.
Has anyone else experienced something similar. And if so, have you determined a remedy?
Any thoughts would be appreciated.
