Gary H Batavia , NY March 08, 2022 Appliance: Kenmore Gas Range 79078572405 Kenmore Range 79078572405: The oven display quit. How to replace Clock Timer. I purchased a new display/control I also decided to purchase a new display "cover". I strongly suggest anyone buy that, as that cover is stuck on and would probably be difficult to remove and use over the new control. An easy job. The worst part was cleaning up the mess under the stove. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
