“Leave the thermostat covers off” ? ? ?
How do you operate the furnace with the thermostat cover off?

Question 2...so we have not camped in ours since late Dec. 2019. It has been parked next to the house, always plugged in to shore power. I moved it to a temporary spot while we wait for an RV cover to be built in the next few weeks, and it is plugged into a 120 volt outlet off the front porch. The polar vortex ice and snow is here in TX for the next week. We are out in the country and lost power Thursday and it was out for 37 hours before it was restored. It will likely happen again this week - so we might go to the RV and run the furnace for some heat...but the furnace will not come on. I did the thermostat reset - but the roof unit fan comes on - no furnace...but only if I pick LOW or HIGH then FURNACE...nothing happens if AUTO is selected. Tried changing the temp...nothing. Now that I think about it - we have not used the furnace since Feb 2018. Any ideas for how to spark it back to life? propane tanks are full and stove burners work great.
