Samar for Model Number SMH9187ST/XAA My previous message: The light stays on all the time whether the door is open or closed and the fan comes on when the door is closed without the food being warmed. Warming/Heating of food works. Samsung Model Number SMH9187ST/XAA As you suggested I tested the micro switch with a multi-meter and found as follows: Switch at the bottom connects to the door: 1) Door Closed: Switch Closed; Door Open: Switch Open 2) Switch just above this Switch: Door Closed: Switch Open; Door Open: Switch Closed (Opposite of the above) 3) Switch on Top: Door Closed: Switch Closed; Door Open: Switch Open. (Same as number one) Given this result what do you think is "not right" so I need to change that switch? Thanks a LOT for your help!
