Se error code Ken E. • Rochester, NY • September 02, 2014 Appliance: Samsung Built-in Microwave Oven SMH9207ST/XAA-0001 My Repair & Advice I wrestled with taking apart the door assembly to get to the keypad ribbon cable connections to the PCB. I had to peel off the chrome keypad facing (its glued on) to pull off the old keypad membrane. (Chrome facing part# DE64-02221A). You need to make sure the ribbon cable connections of the new keypad are seated properly. I've had this unit since 2009 and I almost replaced it. I'm reading where the SE error is common with this model even if you replace the failing keypad but if I can get another 5 years of operation it's well worth the repair hassle.
