Control board that is no longer available, I want a company to rebuild or repair it.

I have had a lot of boards repaired by fix a board good results. We have used both w/good results. However, FixYourBoard does comprehensive testing of their boards. I go with Core Centric -because it is much Faster turn around time, good quality and usually less expensive but regardless of who you have rebuild it, , Always advise the customer that rebuilding is not successful 100% of the time because, just like appliance repairs themselves, sometimes the component need to repair the board is no longer available either or you may get a board back from the re-builder and install it and find only part of the problem was corrected especially depending on who the re-builder is (hint: read the first line above). If this is a run of the mill Electronic Relay Control versus a high-end brand oven controller does affect the success of the repair.
