Doug H Lawton , OK November 08, 2015 Appliance: Kenmore Range Hood 23353345591 Kenmore Range Hood 23353345591: Broken locking tab on range hood light lens. How to replace Light Lens. These plastic light lenses get pretty dirty with grease in a short period of time. This can be a fire hazard if not cleaned regularly. I purchased two new lenses so I can change it out when cleaning. I put the dirty one in the dishwasher so I always have a clean one ready to go. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
