I was recently camped in the Springs Mts outside Las Vegas, in my 2019 hawk, not sure of altitude but probably over 7000 ft. When the temperature dropped, I turned on the furnace. It cycled but did not spark. I moved the thermostat switch to off and back on, it cycled but didn't spark, then cycled off. I left it set at 50 degrees, it was about 30 degrees outside. In the middle of the night I woke up to a warm camper, the furnace ran fine in the morning. This is the second time I have had intermittent problems. I suspect the sail switch is sticking and then after a number of cycles it unsticks.
So I'm wondering if some sort of lubricate on the sail switch might help. My concern would be the lubricate attracting dust and therefore making the switch stick more.
