Customer Questions and Answers for Oven Control Board, Erc by Dacor

Hello Chris, The fault code is indicating a bad connection on S19 or a bad relay board. You should verify that the connections are proper on S19 (double line break relay). If securing the connections at S19 doesn't restore normal operation, replace the relay board. The second fault code indicates that a cooling fan has failed, which can also be caused by a bad board. Note that a fault code beginning with a "u" is an upper oven fault. If a fault code ever comes up for the lower oven, it will be preceded by a "L". The troubleshooting process on these units are very complex. If you could please re-post with an e-mail address, we can include some very precise and useful information with illustrations that will make diagnosing and repairing the unit much easier.
