The door switch that causes my microwave to run it's fan when the door is open is the first one to trigger the microwave to turn off when the door opens. I've swapped it for another switch from an old microwave and it worked for a while, but I'm pretty sure because it wasn't rated high enough, the switch would over heat and the switch would get stuck, so I'm going to try to order one.

SZM-V16-FA-63 seems to be a very popular model, and are easy to find. However, mine is a SZM-V16-FD-63. Only difference is the A and the D. However, all the numbers match, as far as the 16A, 1/2HP, 125/250AC, 0.6A, 125VDC, 0,3A, 250VCD, T130 5E4 u, etc. I can't see how these parts are different at all. Feel like it's just different names for the exact same part. Both are also Normally Open parts.
