My conclusions are as follows:The thermistor has a nominal resistance of 10K ohms at 25C. The Beta value of the original thermistor was ~ 3500.This defined the slope of resistance change versus temperature. The two resistance values of 1100 and 900 ohms therefore correspond to actual thermistor temperatures of ~ 93C and 101C.The closest I can find in a readily available thermistor of the right size is from Farnell part no: 970-7271. It has a slightly different Beta value and will sound warnings at 87C and 93C.I found data from Polymotor which indicated that a max temp of 150C would be OK so there are some big safety margins here.
