Dometic Thermostat issue

[dogwood36322]

My digital Dometic thermostat has suddenly become confused. I have used it in the A/C mode and furnace modes in the past with no issues. This past week it woud tun on the fan for the A/C while in the furnace mode. Any idaes?

Check that when on Fan mode that it is set for Auto, not Hi or Low. Had same issue with mine when furnace kicked in Fan came on.

Thanks 5 hole. My brother in law and his wife stayed in it over the weekend and they must have changed the setting. I wil take a look after work today. Need to turn it on as it is supposed to be in the 20's here tonight.

I have a 2014 Sanibel 3601 with a black two-zone dometic thermostat. I've KINDA figured it out, but is there an instruction/owners manual for this type thermostat I can get or purchase? I don't know if there is a model number on it since I'm in the North and the camper is located as a permanent in a campground and I've closed it up for the season.

Just google Dometic thermostat and you will find several sources to download the manual.

Thanks 5
hole. It was the fan setting. I found my book that came with the camper in all the paperwork.
