I have 2 Accu-Rite Thermos that I got from Lowes last year. It has the metal wire and probe. When I took it out of the cabinet today, it would only say LO. It would read any temp. So I took the probe from my other Thermometer and hooked it to this one and it works. Is there any place I can buy just the wire and probe or do i have to spend another $20 on a new one?
