Topic: heater temperature sensing issues

so i just changed the heater cartridge and the thermistor, and my printer is still reading that it is 7.4 degrees celsius, I only turned on the switch in the back and the printer started heating up the print head when i flip the switch on in the back, Could it be that I put the heater cartridge wires backwards? any suggestions would be graetly appreciatedd

The heater is not polarized so it does not matter. However there is a setting accessed from the LCD that set the printer to preheat when turned on. You may have that option on.

The Da Vinci only display's Celsius.

7.4 would be about 46 degrees Fahrenheit.

How cold is your house?

Mine usually is about 10 Celsius in the morning.

my house is aaround 67-71 degrees fahrenheit. Even when it starts heating the sensor stays at 7.4 degrees Celsius. Thanks

Sorry I misunderstood you.

Only thing I can think of is open circuit in the wiring or plug.

The thermistor should measure about 80-100k.
