The temperature probes are fine with hot glue. Wires are soldered onto the probe, so solder is a lot hotter than hot glue. The only other way to ruin the temperature probe is to plug the probe in backwards.
Check your probes again, maybe they are still working.
yea i switched them around, tried different headers and no joy, whats the max temp those can handle? my glue guns 360. still saying fatal search error 03
I apologize for the confusion. I interpreted the problem differently. Looks like the hot glue damaged the display. The operating temperature range is -55 to 125C. The reflow oven temperature is 220C . For more details on the temperature probe we provide go to http://pdfserv.maxim-ic.com/en/ds/DS18S20.pdf.
