The code given in the link I gave works.
Check the hardware. Bad connections or backwards connection on the thermocouple or wrong type will cause problems.
Both the thermocouples I have are K type and are connected properly. The ground lead on the thermocouple is tied to ground as well as the negative input on the MAX6675 as demonstrated in the datasheet. I did a continuity test on all wires coming from the chip and they're all good.
