I have a vanner 12-1100. I’m not getting any ac out. I’ve tried resetting the gfci within 10 seconds of cycling the on/ off switch. Normally when I reset a gfci, I hear a click and the button stays in. I’m not getting that. Could the gfci be bad?

Symptom: The LifeSine inverter does not turn OFF when the remote switch is turned OFF. Cause: Older Vanner ambulance inverter remote control arrangements (the LifeStar and the IFM1), could accept two remote control signals. The inverter treated two remote signals as if two switches were operat- ing in series.
Remote Mounting Pattern Two optional remote status display panels are available for the LifeSine LSC12-1100. One is for Charger Status (Part Number – LSCR) and the other is for Inverter Status (Part Number – LSIR). (These are the same remote status display panels used with the Vanner LifeStar inverter/charger.) Both the Charger and Inverter Remote Status Display Panels contain a green and a red LED indicator light.
