In the past year, I have gone through several meat thermometers (the kind with the display that stays outside the oven and the metal probe stays inserted in the beef/chicken/lamb item in the oven). Each time, the metal cord connecting the probe to the display unit inadvertently touched the heating element and scorched so that the display said "HI" instead of the proper meat temperature. Can anyone offer me insight on what I am doing wrong? It's annoying to keep replacing these. Thanks in advance.
