Issue:
Discharge Temperature Sensor
Resolution:
- The discharge temperature exceeded the trip value of 275F
- The discharge temperature sensor or wiring is open
- NOTE: On units build in 1992 and later (prior to design sequence C0), the discharge temperature sensor will not be present
- This sensor is no longer available and the input E1 & E2 on the compressor module must be jumpered
- If the diagnostic continues with the jumper properly installed the compressor module must be replaced
