How do the microwave oven manufacturers allow a metal (stainless?) probe to function properly as a temperature sensor? When I experimented by putting thermocouples or metal tubing inside the cabinet through the vent holes, they get quite hot even though I ground them well to the cabinet. There was a time you could buy microwaves with probes covered in a flexible armoured conduit (~1/8 inch OD)to verify meat was cooked. Regardless of if they were thermistors or thermocouples, they should get hot and give false readings or even arc or burn. Or is there a trick to that?? What is the trick?
