I have a 2015 GENIE GS1930 ERROR CODE " C021 : PCON NOT DETECTED". Repair Manual Possible Cause: 1) PCON Disconnected.
2) CAN Communication Failure. 3) GCOPN or PCON ECM. When I go up with the Lift about 10-ft., Lift Stops and give Error Code C021. I press the "Stop" button to reset and try to go up. Lift stop at about 2-ft and give the Error Code C021. I reset it and does the same thing at another 2-ft. I switch to "Ground Control" and does the same thing.

I switched "Platform Control" with a working "2-Button Gen 6 Platform Control" and same thing. I switched the "Ground Control" and gave a different code from the start, "C051: SYSTEM FAULT TILT: NoCal".

I want to call Genie Support, but there's NONE. I tried to find any Genie Scissorlift Forum, but there's none. Only Forklift Action. Can someone help me?
