Hey Guy's ,Do any of you know of a person in the east that rebuilds Webasto 287962 control boxes?? Found a re builder in the Midwest but he is asking around 450.00 for his which seems a bit steep since I have found new ones for 500.00.Do these things have gold contacts or what??
They are expensive! Are you sure yours is bad? Check with Roger: http://www.rvhydronicheaterrepair.com/ (http://www.rvhydronicheaterrepair.com/)

No Opus,I am not sure mine is bad,but through the process of elimination ,I ave about arrived at that conclusion.I can bypass the control bax a get it to work ,but it will not fire up under its own power .As a matter of fact ,the "Webast on" lite won't even light .
Call webasto tech support first and check with them, they're very helpful with diagnosing.
My Webasto quit working and I went through the electrical schematics given in the manual without the benefit of the actual technician's expensive test unit and I figured it was the control module. I found an new aftermarket box on Ebay a lot cheaper than Webasto sells and put it in, but still had the problem of the Webasto not firing up.
So back to the manual and took it apart and the problem turned out to be the flame sensor by taking ohm readings. Replaced it, and it worked fine. So now I have an extra control module-- this was not my first trip around the block, as I has already replaced the control module before and it fixed my problem. So now I have a spare module I can pop in if I have a problem, and if it doesn't cure the problem I know it is something else.
