Are you still there....??????????

Sorry, I have had several customers all come online all at once - I am working as fast as I can.

Let's try a static reset on your unit.

Set the switch to OFF.

Pull the control fuse out of the control panel.

Wait 10 seconds, and put the fuse back in.

Will the genset start in MANUAL?

It starts in manual
Customer reply replied 7 months ago
It doesn't crank in auto. It shows RPM Sensor Loss. I switch it to manual and it starts

When you say it doesn't crank, do you mean the engine does not even turn, or that it turns but won't start?

Have you reset the controller? That should have cleared the fault

Engine does not even turn over. Where is the controller and how do I reset the controller

The controller is the Start/Stop switch

Ask Your Own Small Engine Question
Customer reply replied 7 months ago
I realize it has three (3) positions...AUTO / OFF / MANUAL... I am telling you again that when it is in AUTO it doesn't crank over...it shows RPM Sensor Loss. I would then put it in MANUAL and it starts right away

You have to reset the controller first, to get rid of the alarm.

I would simply put it back to AUTO and the ready light would light. It would shut off the RPM Sensor Loss light
Customer reply replied 7 months ago
Never mind...I am not satisfied with your answers...I will contact Generac direct

Good luck.
