Control Switch Placed in OFF Position
What does GENERAC-0010 mean?
The GENERAC-0010 (Generac Evolution) diesel fault code means: Control Switch Placed in OFF Position. This is a minor severity code.
Common Symptoms
- Panel displays code 0010 and shows the word OFF or SWITCH OFF on the screen
- Generator does not crank during the weekly exercise cycle
- Yellow or red status light is illuminated on the control panel
- Generator will not respond to a utility power outage and will not start automatically
- Mobile Link or OnCue app shows the unit status as OFF or Not Ready
- No audible crank or start attempt is made when utility power drops
- ATS does not transfer the load to generator power during an outage
Probable Causes (Ranked by Likelihood)
- Control panel switch was intentionally turned to the OFF position by the owner or a technician Very Likely
- Switch was bumped or moved accidentally during routine inspection or cleaning Likely
- Service technician placed the switch in OFF for maintenance and did not return it to AUTO Likely
- A child or household member turned the switch without realizing the impact Possible
- Sticky or worn rotary switch that did not fully engage the AUTO detent and slipped to OFF Less Likely
- Wiring fault or intermittent connection at the switch causing the controller to read OFF state incorrectly Less Likely
Step-by-Step Diagnostic Procedure
Walk to the generator and look directly at the control panel. Locate the three-position rotary switch labeled AUTO, OFF, and MANUAL. Confirm the switch pointer is sitting on OFF.
If you want the generator to return to normal automatic standby operation, turn the switch to AUTO. The display should clear code 0010 and show READY within a few seconds.
If the switch is already pointing to AUTO but code 0010 is still displayed, press the switch firmly to make sure it is fully seated in the AUTO detent. A worn switch can sit between positions.
After moving to AUTO, press the Enter or scroll button to clear the fault history on the Evolution controller. If 0010 clears and READY appears, the unit is fully operational.
Check Mobile Link or the OnCue app after 2-3 minutes. Confirm the status updates to Ready or Standby. If it still shows OFF, force a status refresh in the app.
If the switch physically feels loose, does not click firmly between positions, or the display still shows 0010 after moving to AUTO, the rotary switch itself may be faulty. Test switch continuity with a multimeter across the switch terminals with the switch in AUTO -- you should see continuity on the AUTO signal wire. This step requires removing the control panel cover and is best handled by a technician.
If no switch or wiring fault is found and 0010 keeps returning on its own, suspect a controller board issue and contact a Generac dealer for further diagnosis.
Frequently Asked Questions
What does Generac code 0010 mean?
Code 0010 means the control switch on your generator panel is in the OFF position. This is an informational status, not a hardware fault. The generator is simply turned off and will not start automatically if your power goes out. To fix it, turn the panel switch from OFF to AUTO.
Can my generator still run with this code?
No. While the switch is in the OFF position, the generator will not crank, will not respond to a utility outage, and will skip its weekly exercise cycle. It is completely disabled until you move the switch to AUTO.
How much does it cost to fix?
In most cases, it costs nothing. Simply turn the switch back to AUTO and the code clears immediately. If the rotary switch is physically broken or faulty, a replacement switch costs $25-$75 in parts. With a technician labor charge, expect $100-$250 total for a switch replacement.
Will the generator start the next time the power goes out?
Not while the switch is in OFF. The ATS will not signal the generator to start, and your home will stay on utility power only. Move the switch to AUTO as soon as possible so the generator is ready for the next outage.
