This manufacturer-approved primary micro-switch (part number 4392027) is for microwaves including Whirlpool microwave model number GT4157SPB0.
Primary micro switch 4392027 is one of the door latch switches.
The switch monitors if the door is open or shut.
Because microwave ovens contain high-voltage capacitors that can retain a lethal electrical charge even when the microwave is unplugged a service technician should install the primary micro-switch in the microwave.
