Does this probe have a 1/4 inch insertion probe into the temperature port of the stove?
Yes this probe is a meat probe that will plug into the jack inside the oven. We do not have the size opening dimensions of the plug in but appears by the picture to be about a 3/8" diameter.
Meat probe sign is on display and temperature reading while oven is off position.
Answer Hello Asif. It sounds like either the probe jack is shorted out or the control board is bad and will need to be replaced on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
