Job Checkin

Tech found system had high head and low suction in heat mod at 45/600. Tech force opened the EEV and found suction get to 140 and head pressure down to 419. This indicates the stepper motor and EEV are able to open properly. Tech verified the suction pressure transducer dc voltage is matching the suction pressure based on the product service information. The suction line sensor was 2k ohms off and tech insulated the pipes to prevent the sensor from grounding and found it reading properly but the suction pressure still was too low. The board is receiving the call to open the valve and the valve is able to open, but the board is not sending the signal for the stepper motor to open. Suction line sensor will need to be replaced as well. Tech left test open
