Frequently Asked Questions

What causes Generac error code 1300?
Error code 1300 is caused by RPM sensor loss, typically due to a failed magnetic pickup sensor, damaged wiring between the sensor and control panel, loose connections, or incorrect sensor gap spacing from the flywheel.
Can I run my Generac generator with error code 1300?
No, you cannot safely run the generator with error code 1300. This error prevents the control panel from monitoring engine speed, which is critical for safe operation and preventing engine damage from over-speeding.
How much does it cost to fix Generac error code 1300?
The cost ranges from $30-80 if you replace the magnetic pickup sensor yourself, or $150-300 if you hire a technician. The sensor itself typically costs $25-60, with labor adding $100-200 for professional service.
How do I reset Generac error code 1300?
You cannot simply reset error code 1300 without fixing the underlying problem. After repairing the magnetic pickup sensor or wiring, clear the code by pressing and holding the Enter and Escape buttons simultaneously for 5 seconds on most Generac models.
What is the magnetic pickup sensor gap for Generac generators?
The magnetic pickup sensor should be positioned 0.020 to 0.050 inches (0.5 to 1.3mm) from the flywheel teeth. Use a feeler gauge to check this gap and adjust the sensor mounting position if necessary.
