Lindsay B Katonah , NY June 12, 2017 Broken lower pan fram After reading previous reports about how to replace this piece I was skeptical whether I could fix it without breaking a piece. I was very careful and it took longer than expected (30-60 minutes). There definitely needs to be some instructions or video to help the customer. I did wait for the old frame to warm so it wasn't so rigid and needed just screwdrivers and lots of patience! Removing some of the old pieces like rubber seal and humidity controls was relatively easy if you just look to see how they were placed in old frame. I rated my experience four star because I accomplished what I set out to do! Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
