Replacement or repair of motor for leveling jacks on 2007 Newmar Canyon Star 3303

[Pat O'Sullivan]

This past fall, when trying to raise the LF leveling jack, the leg came up about 6 inches, squeeled and then stopped. In order to raise it all the way up I had to wedge a 2x4 under it and while the raise button was being pressed I used the 2x4 for leverage to force the leg up. I have an appointment with a local RV dealer and anticipate that it might be the motor that is not working. The other 3 legs raise and lower normally. Since parking it in October I have not tried to use the leveling legs yet. My inquiries indicate that the jacks are an Atwood product and no longer available from Newmar. I live in south central British Columbia, Canada.
Anyone have a similar issue and if so how was it solved?
