Diagnostic/ Condenser short cycling, system not heating. Arrived and found the condenser locked out on error codes #4 and #7. These error codes are for EEV restrictions and a failed suction line temperature sensor. I have ordered these parts and they will be likely be in later this week. Only emergency heat is available for now. 2/12 - Returned and replaced the suction line temp sensor, the EEV stepper motor, and the EEV control board. Tested operations in heat mode and cool mode. The system is working properly at this time.
