Found unit off and burners very dusty. Removed burners and cleaned. Unit may need a flame sensor if the cleaning doesn't fix issue. Will order and install. 2-13-17 replaced flame sensor. Turned unit on, oven lit right away and cycled off at 382*F, set at 375*F and turned back on at 373*F. Unit is back in service at this time. 2-17-17 found unit off, turned on and let heat up to temp. Unit is heating and cycling normally. Watched unit cycle for 1 hour with out issue. Checked ignitor, module and flame sensor, all are working properly. If problem persists, recommend replacing module and ignitor.
