A956_O: Suction Pressure Sensor Failure
On the VSODC, this will be indicated by a number 36 on the seven segment LED display
The Drive LED's will not indicate anything
This alarm indicates the suction pressure transducer in the outdoor unit is either disconnected, open, shorted or otherwise has failed. Its a good idea to unplug and re-plug the harness back in at both connections to see if it was simply a matter of a loose connection. While this is unlikely due to the robustness of those connections, its always worth checking.
If the connections feel secure, the next step is to check the transducer with the system powered. Please follow the procedure for checking the transducer with the button below.
