problem with temperature readings

When i start my 3d printer up (it's a CR 10s pro), the nozzle temperature reads 226 degrees Celsius despite the nozzle being cool to the touch, and my printer bed reads 30 degrees Celsius when I know for a fact it is not. I tried replacing the thermistor on the nozzle and the temperature reading was 226 degrees when the thermistor was unplugged and when the new thermistor was plugged in, so the thermistors are not the problem. I will mention that the temperature reading sways from around 225 degrees to 227 so it is reading SOMETHING in real time. Please help, and if you want any additional information to help solve my problem, please ask, thanks!. a Picture is attached
