Hi my name is ***** ***** are you refering to the thermostats or the NTC sensors?
At 25 Centegrade the reading should be around 19.5K ohms
Have you checked the mechanical thermostats on the heater and near the heater, you should have continuity through them and are you getting any power to the heater?
Check it is a thermostat rather than a NTC thermistor ~ power to heater?
No problem - would you now kindly rate the information by using the star rating system at the top of the page to allow me to shut the job down on my screen. Thank you for using JA and have a nice afternoon. - Ian
