Auto Close Vent Freeze Up/Condensation Problems

[TrailTrackers]

Hello... I woke up this morning to a 3 tone clicking sound in the trailer. Tracked it down to the vent in the back bathroom. In short, we are in Utah and there is snow and ice on the top of the trailer from a big storm then freeze. There was a build up of condensation and it was triggering the auto close. But with it already closed it was just heating up to the point of smelling like wanting to catch on fire.
First thought was... Why the hell don't they have an On/Off button for the auto close feature on the keypad with the other buttons?!? I guess that would have been too easy, and too much common sense would have been required to think of that during design. That's the problem with engineers designing stuff that they have/will never use.
In any case, is there an easy way to disable that feature for the immediate future? I looked for a breaker but there isn't one labeled for that vent, nor for the "bunkhouse" bathroom. Or perhaps there is another "quick" solution to this problem that somebody has thought of? Without being able to "shut it down", I got my wife's hair dryer and dried the area which worked in the very short term; dried it off enough to stop it from attempting to close repeatedly. But to be honest, I would like to just disable the darn feature for an extended period.
My long term goal with this issue is going to be to track down the power wire to the auto close sensor and extend it to an On/Off button on the bathroom wall.
