I have a strange Suburban Furnace issue with intermittent air flow and strange noises. It runs fine most of the time especially when keeping the trailer at temperature but once on the last trip and several times arriving here in Ottawa it does this.
1. Will run fine for at least 1/2 hour or more. Ran fine 45 minutes yesterday and this morning.
2. Can hear the airflow slowing down and starts making strange sounds (almost a rumbling that slows and increases with speed)
3. Airflow really slows down but increases and decrease up and down. Can hear the blower struggling as well.
4. Finally stops.
If I let it sit for a bit and turn off the thermostat and then turn it on 15 or 20 minutes or more later will run like normal again. Did this 3 times a couple of days ago when bringing up the trailer to temperature from about 8C (46F) to 22C (72F). Even from 19C (66F) it did it the last time.
This is on shore power and the first time was on battery power. Initially I thought it was low battery but now I think it is bearings but it seems to run fine 95% of the time. If it was bearings I would think it would be an issue all of the time.
It does also have a bit of a high pitched whine to it that I have not had in previous trailers before which I assume could be bearings.
I have been timing it to see how long it runs before it happens but of course now it doesn't happen.
Propane tank if full and all of the electrical is working fine and battery shows full charge.
Any additional insight is much appreciated as I suspect the dealer will run it for 20 minute and say there is nothing wrong.
Thanks,
Rob
