updated December 26, 2012 | critical DIY safety info
Symptoms & Fixes
- bad outlet or blown breaker - test outlet's "under load" performance with a hair dryer or toaster
- defective "control unit" (circuit board assembly) - Note: The Dacor, Viking & Wolf models are all versions of the original Sharp R-530E-series ovens, and the best fix for this problem is to order a new Wolf version control unit, part number 815587 from Southern Coastal Parts at 877-861-0955. You can tell them it's the one for Wolf model MW24. The only difference is the text displayed at startup which goes away when the clock is set. See service manual for disassembly info.
- keypad strip may need to be cleaned - See service manual for disassembly info, unplug the keypad strip, then use only a soft pencil eraser to gently clean both sides of the strip, then reinsert strip & reassemble oven.
- moisture, grease, or other foreign deposit (usually grey, green, black or white) on circuit board, especially near keypad strip - See service manual for disassembly info, remove circuit board and gently clean any deposit with a soft toothbrush dampened with alcohol-based cleaner only, not an ammonia-based cleaner. Never spray cleaner directly on the keypad or controller.
