Dacor Oven U43 and L43 Errors

Dacor Oven U43 and L43 Errors indicate a problem with oven relay boards, specifically a bad connection on the S19 relay on the relay board. It covers Dacor Discovery oven models: EO, PO, MOV, MOH, SINGLES AND DOUBLES, 27” AND 30”.

To confirm the error and do the oven component check, we should use a service test. To enter the service mode, hold CANCEL/SECURE and # keys at the same time. When the diagnostic password screen appears, release the CANCEL/SECURE key first, followed by the # key. Enter code S2010.

To fix this problem, Dacor recommends replacing both relay boards for the upper and lower ovens. For most of the models, the manufacturer discontinued those relay boards so that the only solution will be reconditioning the old ones.
