How to replace Oven Clock Overlay. It was so easy, did not even need a repairman. First I watched the repair video from AppliancePartsPros on YOUTUBE. Then I just took the back off, unplugged all the connectors and put them back on the new part correctly. I did put a new overlay on it since I had it apart. Thought I would need a new stove, but this easy repair saved me a lot of money. The fast shipping helped since my microwave stopped working the same day and I had nothing other than my grill to cook on. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
