I may have a stupid question, I'm sure you guys can let me know. I'm dealing with a GE Artica Frig and I'm checking thermistors. I placed Frig thermistors in ice water and took 3 different meters and readings at 32 degrees. All 3 readings read 14.5K, and suppose to read 16.3K. Do we have room for error or are these bad thermistors. Thanking you guys for your valuable time in advance. Jack Last edited on Sun Oct 24th, 2010 03:44 am by jwlowe |

what is the amount of k ohms per degree or do we have available a chart with more degree readings than the one above? By the way thank you for your reply.

It is not a linear equation and it is not simple. but for simplicity, you can take a desired temp like 34 you have the readings for 32 deg and 41 deg so for 9 deg difference you get 3.6 kilo ohms difference for every deg over 32 subtract .4 kilo ohms it is not completely accurate, but good enough so 34 deg would equal 15.5 kilo ohms
