Title: Pos-A-Loc and Cold Weather
Post by: J. D. Stevens on January 08, 2015, 10:53:20 pm
On our recent trip to Montana, we experienced problems with the Pos-A-Loc system on the entry door. In temperatures below about 15F, we could not get the inside. nor the outside, handles to unlock the door if it was adjusted so it would release the "hold open" catch at the top of the door. The solution was to remove the inside cover for the lock mechanism and loosen the two screws holding the cable to the "hold open" mechanism. That worked great until temperatures rose and the door swung wide open. In that circumstance I had to readjust the release mechanism in order to close the door.

My hypothesis is that the cable gets enough moisture in it to freeze when the temperature drops low enough. The cable mechanism prevents the handles from releasing the door catches. It is in the "condensing/freezing zone" between the warm air inside the coach and the very cold air outside. Releasing the adjusting screws for the cable allows the handles to release the door catch, but the handle no longer will release the "hold open" catch.

Perhaps there is a way to adjust the system to deal with the issue. I think our solution will be to avoid travel to areas where the temperature will be below 20F. I'm pleased to have gone on our four adventures to Montana in December/January, but I think we will rearrange schedules to visit family under more favorable conditions.

Excellent solution.

J. D.
Glad to see you made it back from the north. We met you on our way south in December. You are braver then we are.
Safe travels

JD,
Agreeded, a trip South will solve your lock problems.

Not necessarily.

Mine lock up in cold or heat.

As has been noted here earlier, taking the internal door cover off and applying graphite helps.

Then, just yesterday, I noticed that if I disengage the latch while outside, and THEN pull to open the door its easier than to do it in one fell swoop.

best, paul

A few ideas:
1.  Lubricate cable and install rubber boots on ends if possible.  Lube will ultimately dry out so it would need to be re-done on some kind of schedule.
2.  Install heat tape.  Same as what is used on pipes.  Possible space issues as well as power feed to door to be worked out.  12 volt heat tape is available too.
3.  Maybe you can limit door travel in cold temps so the feature isn't used?  Can't image you want to hold the door open when it's so cold outside.

I like your solution as it is similar to ours for winterizing. We winterize by driving south.
