Hi, sorry no one has responded. The 109kohms is pretty accurate to the temp you are reading. I would guess either there is a poor connection or the temp sensors are defective. I will provide an attachment to the sensor resistance chart.

You connected these sensors to thermostat wire correct? Are you check resistance directly at the sensor or at the thermostat? Thanks
