Lisa G San Antonio , TX October 10, 2015 The hous cntrl unit had basically crumbled in my whirlpool stove overhead vent Using a six-sided screwdriver tool I loosened the screws, pulled out the old unit, and replaced it with the new one. It took less than 5 minutes. Easy fix. I'm a happy customer!!! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
