We have a 2016 Montana with two air conditioners. The front one in the bedroom will not run continuously with the fan set in the low position. There are three settings for the fan, Auto, Hi and Low. If you select Auto the fan will cycle on and off with the compressor. Set to Hi the fan will run continuously wether the compressor is on or off and continues all day if you leave it as such. Now here's the problem, when set to Low, the fan will run continuously wether the compressor is on or off but will only continue to do so for a couple of hours, then shuts off. The front air unit will run continuously on Low for how ever long you leave it like that. We like to sleep with the fan on continuously on low so we have air circulation but like I said after a couple of hours it shuts off. Any ideas what is goin on?
