The 10811-60111 that came in my 5370B counter turned out to have an open circuit Thermistor in it. This is a "non-replaceable" part in theory.
However, nothing to lose, I have successfully substituted a Digikey Part number: 317-1371 100 kOhm 1% Thermistor ( from Cantherm, part number: MF51B104F3950 ). I measured the resistance of it at the target oven temperature, working back from the selected value of R20 that was installed in mine, in this case 0 Ohms for 84C. In fact this thermistor must be very similar to the one used originally, since I only needed to use a value of 110 Ohms for R20 to get bridge balance, instead of the short that was in there previously. Good enough for me...
