B. Control way of Error (if any)
1) "R1" error
• Cause : R-Sensor disconnection or short
• Check Point :
- Measure the voltage between terminal PIN 7 and 8
after separating CN5 on the Main PCB.
- If the sensor is disconnected, the voltage is under 0.5V. Change the sensor.
- If the sensor is shorted, the voltage is over 4V. Change the sensor.
2) "RT" error
• Cause : RT-Sensor disconnection or short
• Check Point :
- Measure the voltage between terminal PIN 1 and 2
after separating CN4 on the Main PCB.
- If the sensor is disconnected, the voltage is under 0.5V. Change the sensor.
- If the sensor is shorted, the voltage is over 4V. Change the sensor.
