    a Long screwdriver bit in the cordless drill will make short work of it. Or Just a long screwdriver.

    You mean coming through from the other side? (My finger is sort of pointing..)

    The head of the screw driver is on the outside, facing the bunk end. I attempted to take the entire box out but, duh, the furnace is HEAVY and I can’t seem to get it far enough out.

    Can you just reach up and hit the little button on the switch? I'm sure they didn't design it to be taken apart every time it needs to be reset, I could be wrong.

    I can’t reach or see anything. The DSI plate blocks it.

    Well, I was able to bend the metal easily but I’m still not sure what I’m looking at.

    I think it's the round black thing with the 2 wires on eaither end of it. Feel both sides of it for a dot, it's a push switch

    A limit switch, or rollout switch gets triggered by heat that rolls out of the furnace box, so it will be closest to the furnace box. It cuts off the power to the unit before you get a fire, a clogged vent can also make this happen, or a windy day with a down draft on your flue

    Sorry I thought you were trying to pull the whole heater out.

    I can’t tell from the pic but is the screw head like a bolt head if so use a small wrench. Keep us posted.

    It should come out with a quarter turn. It's small

    Guys, I feel like a dork. My husband woke up and asked, “Why not just use a socket wrench?” (A regular wrench didn’t work)

    I think the limit switch is the small round thing with two pink wires coming out of it.

    My other question is if it’s just an Airflow thing, where are the pipes that need to be cleaned out?

    I haven't a clue. I really only know a bit about regular furnaces, I never looked at the one on my camper yet!

    It should have a reset button on one side or the other.

    Haha, well you have now! We’ve got the limit switch unscrewed from the back plate but no clue how to by-pass it.
