Gary S Hammonton , NJ September 22, 2014 Appliance: Model SAMSUNG SMH9187W Se error code microwave acted as if it was haunted would turn on/off by itself change settings etc internet research indicated a likely touch pad/control pad gone awry It was an easy fix. Purchased a replacement control panel that included a new touch pad. It took about 20-30 minutes to swap out the old one. Works fine now. No longer haunted.
