Error Code C-20
Temperature sensor open circuit detected
Critical
Stop using immediately - risk of damage or safety issue
Also displayed as: C-20
What This Means
Sensor connector disconnected at main PCB; Sensor connector disconnected at sensor; Faulty temperature sensor; Main PCB failure
What actually causes this:
Loose connector, broken sensor wire, or failed sensor element
First Thing to Check
Inspect and reseat sensor connector at both the main PCB and sensor terminals
Parts Involved
How to Fix
- 1
Check whether connector at the main pcb has been inserted
- 2
Check whether connector at the sensor has been inserted
- 3
Check sensor resistance at room temperature (1080 Ohms)
- 4
Measure resistance of connector CN320 of Main PCB (Open: infinite Ohms, Short: under 10 Ohms)
