brodick@shaw.ca Report post Posted November 11, 2010 Onan Trouble Shooting Guide: http://www.cumminsonan.com/www/pdf/manuals/981-0161C.pdfBrett Thanks but I have that manual. Have traced the problem to the control board. A replacement from Cummins/Onan is $750.60 ! As luck would have it, Flight Systems do not have a functional test for this particular board. Hoping to find someone who can do a repair. Share this post Link to post Share on other sites
wolfe10 Report post Posted November 12, 2010 I just received this reply to a copy of your post I sent to an Onan tech I rely on: "As this is relatively new, might give the folks at Flight Systems a chance at it. Talk to John Weaver there, they may take it on as a sort of trial/experimental case." Brett Share this post Link to post Share on other sites
brodick@shaw.ca Report post Posted November 14, 2010 Anyone else have ANY kind of a circuit board repaired? There must be SOMEONE who can repair as opposed to just going with a new replacement! Maybe an indication of where society is headed - R&R - Remove and Replace - a throw away mentality. Trying to recycle but....... Sad. Share this post Link to post Share on other sites
garykd Report post Posted November 16, 2010 Hi ISM500, Consider Googling "305-0953-03 control board repair". The response will provide quite a few companies that do this. I do not know if they can help you, but it might be worth a try. Share this post Link to post Share on other sites

I do not know if they can help you, but it might be worth a try. Have "googled" and "binged". Have tried more generic searches. Chased down countless links and dead end streets. Still coming up empty handed. Our travel plans are on hold for other reasons but it sure seems like that new replacement board is looming. Here in Canada it's over a thousand dollars. Must be made from unobtainium for Onan to be charging that kind of money. Share this post Link to post Share on other sites
