A good MOSFET should have a reading of 0.4V to 0.9V (depends on the MOSFET type). If the reading is zero, the MOSFET is defective and when the reading is "open" or no reading, the MOSFET is also defective. When you reverse the DMM probe connections, the reading should be "open" or no reading for a good MOSFET.
How Do I Know If My Capacitor Is Polarized or Non-Polarized? Identifying a capacitor type is key.
