Steve K Warrenton , VA May 10, 2016 Appliance: Model SAMSUNG ;SMH9207 The fan button on the front of the microwave was pushed in and would not work Ordering and receiving the parts was easy. Everything came promptly and was well packed, Installation was another issue. The 4 switch assembly as designed my SAMSUNG is very cheaply made and extremely difficult to install. It is a shame that SAMSUNG doe snot provide a service manual and break out DWG--would have made it easier. The easy part-- I unscrewed and top vent louver --2 screw and removed it easily. Then I had 1 screw to remove and lift out the right front panel of the microwave which is were the switches one. Since I could not gain access to the switches-- a poor design if they would have moved a bracket 1/2 inch I would have been done, Instead I had to unhook all the wire connectors and remove the entire panel. Then I had to remove the mother board which was mounted to a metal bracket and remove the metal bracket to get access. Getting then re-install-- glad I took picture with my phone and didn't trust my memory. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
