E9 Outdoor

Temperature Sensor

Open or Shorted

1. Check the sensor connection at the power board�

2. Remove the wires from the terminals and measure

the resistance� A short circuit will have a resistance

very close to 0 Ohms and an open circuit will have a

very high resistance� The table at right can be used

to approximate the resistance based on outdoor

temperature�

3. If the sensor is not reading correctly, replace the

sensor, Part No� 8052�
