Victor G Lakewood , CA September 12, 2020 Appliance: Frigidaire Range FGFL79DSE Frigidaire Range Fgfl79dse: Touch screen blank. How to replace Clock Timer. Ordered the clock/timer panel; removed top back cover to access the panel. I found it easier to disconnect the wiring harness before removing the four screws that hold the panel, after removing the panel I very carefully peeled the overlay off from old part. (I used a sturdy plastic kitchen spatula to start the removal once it peeled off a bit I pulled off gently with my hands to remove it completely.) I then replaced the overlay on the new panel and reversed the removal steps to finish the job. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
