    On our 2007 Bayside I finally realized that the thermostat doesn’t actually turn off when I switch it to off for the day. It cycles properly and keeps the trailer at the right temp during the night. But then after I switch the flip to “off”...it still comes on. I have to lower the temp as low as it goes to get it to turn off.

    Does this mean we need a new thermostat or is there a deeper problem with the furnace? Luckily the temps are above the lowest setting during the day time so I’m not wasting propane, although if they were I’m not sure how to stop it short of turning off the propane at the tanks and unplugging the battery.

    Pop the cover off the thermostat and visual check that it is working.

    You could disconnect the Thermostat. The switches are a PITA. My guess is that its not turned off all the way. @NMroamer said take the cover off and you can see what the switch is doing.

    X3 If it is the thermostat a new digital one can be had from Wally World for less than $20.00
    they are easy to install . Good Luck and happy Camping

    Thanks! I briefly tried removing the cover but it didn’t want to come off. It looks like the old brown stock one.

    I’ll keep trying.

    Just stick a screw driver under the edge.

    The switches on those old brown tstats are notorious for requiring a great deal of force to throw. My first check would be to make sure you're turning the switch all the way to the 'off' position.

    I did. I can feel it click. That was my first thought, too. Did I just not push it hard enough? At least from the outside of the box it’s clicking and I can’t push it any more.

    they are good for feeling like they'll break, if you pull the cover off and watch it while you switch it it'll flex and look like it's going to break. I got tired of fighting with mine and replaced it with a digital on.

    I’d prefer a digital one as well. Maybe before our next trip! The lows where we’re going is supposed to be 68.

    I always thought I was turning mine off, until I took the cover off last fall and observed the switch in action. It turns the little "click" I was feeling was not the off position. It took quite a bit of force to push it into the off position. Now I know where the off position is, and if there is any questions, I pop the cover off to confirm.

    funny where i'm going I'm hoping it makes it up to 38, the lows will be in the teens.

    But that’s why we have trailers, right?! To extend the camping season! We went camping for my birthday in November with nighttime lows below freezing and were toasty comfy. Which was a nice thing since it was our first trailer trip!

    Wow! You guys weren’t kidding! I took the cover off and what I *thought* was the click was NOT. There is a distinct hard push to get it to turn off. I feel much better now. The thermostat mod can wait a little bit now. I am just way too busy.

    I used a tiny hammer and worked the switch back & forth until it got a little easier to move. I will probably need to do it again this season.
