Ok , I doubt you can access the sensor and wiring trough the roof vent .
So; unfortunately ; the fridge has to be removed from it's cabinet to get at the wires.
Do you have your fridge's manual ?
The manual should contain the installation instructions , so you just reverse the procedure.
Shut off and disconnect propane , 12 volt wiring and 120 V cord.
Usually 2 screws at the rear, one at each side at the back of the bottom frame rail ; accessed through the lower vent ( as in black circle in picture below ) and 6/8 around the front flange , then the fridge will slide forward.
If you're working by yourself you'll need a sturdy platform to slide the fridge onto as you move it forward .
