I believe that the Sport 22FB is the only current model AS that has the automatic, 3-way fridge (12v, LPG, 120v). BTW, the 12v
seems to work well when travelling and my Jeep heavy duty alternator seems to be able to keep up with the draw.
The only PDF manual
that I was able to find online with a similar Dometic fridge has the following photo with this description of operation for storage: "Release the locking mechanism of the door lock by pushing it and shift it to the front. If the door is shut in this position, a small gap is nevertheless kept open to prevent formation of mildew.
When putting the coach into storage for a few weeks I like to have the door held partially open to prevent mildew from forming inside. This mechanism works to hold the door open, but prevents it from opening more or closing. The door is unlatched in the usual way by pressing the release on the top of the door.
I was able to get this mechanism to move into the storage position, but had to partially remove the clear plastic cover in order to get the latch gate to move forward. Is there a trick to make this operation easier?
