How to replace Clock Timer. My oven had no heat so we did the easy things first like change the terminal strip and the oven temp probe. These did not fix the problem. I checked both oven elements with a multimeter and these had good continuity. So no reason to replace them. The next thing was to replace the oven control. This was about a 25 minute repair. Watch the video it really helps. I also did a chat session to confirm the next part to replace. The parts were ordered that day and they arrived the next day with standard shipping. The oven is working what a relief and no expensive repair technician required. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
