Mike check my code....
My temp does not freezes. I believe most people here has the same problem, but I think I found a way and I am running it right now.
I took the concept of blink without delay. Also used it on my RELAY1 and RELAY2 function. I just duplicated it and created a THEMISTOR function.
Take a look here.
Maybe you can do the same with your DS18B20???
I first created and defined the function PRINTTEMP outside of the loop...
Then i just inserted the function and call it out inside the loop for the FADE IN, MAX, and FADE OUT. Together with other functions that need to run while fading in and out.
Hope this helps.

PHP:
{
onesecond(); // updates clock once per second
countdown--;
relay2();
relay1();
printTemp();
}Hope this helps.
