Benjamin G Farmington , MO August 10, 2015 Appliance: Kenmore Dual Fuel Slide-In Range 79046813991 Kenmore Range 79046813991: Oven door would not close completely was causing heat to escape and apparently causing the control panel to malfunction with an f1 error. How to replace Hinge. Replaced both hinges. I found that they were both sprung and causing the door to close crookedly. After the repair, the door closed better than it ever had. I bought the oven from Sears as a customer return, but didn't notice the door problem until years later. It just got worse with time. I am hopeful that the F1 problem will not return. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
