1. Anet A8 LCD display shows temperature is "def".
Step 1. Click Reset.
The temp will turn to def in a second after clicking Reset. As image show above, the extruder temp is -50.9 means thermistor cannot detect temp.
Step 2. Change wires of E_T and B_T port and click Reset.
● If step 1 & 2 both show abnormal extruder temp, you need to replace extruder thermistor.
● If step 1 & 2 both show abnormal hotbed temp, you need to replace hotbed thermistor.
● If step 1 shows abnormal extruder temp while step 2 shows abnormal hotbed temp, you need to replace the mainboard.

2. Anet A8 printer's extruder temp doesn't rise.
Please check the mainboard and screen:
● Click Quick Settings - Preheat PLA on screen, then "Preheat PLA" will appear.

Please check screen operation and hotbed connection:
