Quotekeremdikmen Finally i solve this. Firstly thermistor's capacitor is failure and because of i see wrong value on screen. After then i replaced it but i can't properly solder resistor so its give wrong value again. Now both are okey and i see true value. Thanks for help Where do you buy replacement for C15 and R17?
