FWS Won’t Open

[Olroache]

Periodically my FWS won’t open. I cannot find any rhyme or reason. The locks will close but it won’t move. In the past I’ve shut everything down, put the coach in storage mode, waited 2 minutes, and then it worked. Recently that hasn’t worked initially and I would do it 3-4x and then it would work. Kind of exasperating not knowing when you’re ready setup if the slide will open. The controller was replaced by Newmar dealer in November 2017. There has never been an issue with closing the slide just opening. Any ideas?

Thanks

Probably a loose connection in one of the interlock inputs. For example 10 volts on an input requiring 12 or 3 volts on one that should be zero. I'd get the diagnostic troubleshooting instructions from the controller maker and go through the process next time it acts up.

Good luck, intermittent faults are always the worst to troubleshoot.

I didn't realize it, but Newmar wants the engine running on the 2019's when opening the full wall slide. Give that a try.

Did you find that in the 2019 guide book?

Olroach;
I had a 2008 DS for 10 years with those
locks. There is a magnetic proximity
switch behind each lock arm. They both
have to be engaged before the slideout
motor gets power. If the arms retract and
the slideout doesn't move try tapping the
arms with a hammer to engage the proximity switch. If that doesn't work tap harder,you can't hurt anything. If that does work, the switch isn't normally making contact with the arms retracted as it should. Lubing the arms might help.

Thank you!

I’ll try that. I only have access to the lock behind the driver seat when slide is in. Thanks!

I passed that information on to Don after talking with HWH technical service department. This is why they changed the 19’s and up to operate with the engine running.
