Fault Code E07 – Briggs & Stratton Series Pro 3

Meaning: The system detected an overload or surge condition and limited/stopped output.

Common causes

• Loose or damaged wiring/connector
• Connector corrosion, moisture intrusion, or contamination
• Out-of-range operating conditions
• Component wear or intermittent failure
• Improper installation or setup
• High inrush starting load (motors/compressors)
• Dirty air filter or restricted airflow

What to check first

1. Power down the unit before inspection and allow it to cool (if hot)
2. Disconnect loads and restart; reconnect one device at a time to identify surges
3. Verify connectors are seated and wiring is intact (no pinches/cuts/burn marks)
4. Confirm supply power is within specification for your unit
5. Remove debris and ensure proper ventilation/airflow
6. After correcting the suspected cause, power-cycle and retest
7. Verify oil level/type and fuel supply quality (as applicable)

Is it safe to keep running?

Maybe. Reduce load/stop the cycle if symptoms persist, then troubleshoot to prevent damage.

Reset guidance

After correcting the underlying issue, clear the fault by power-cycling the unit, then retest during normal operation. If the code returns, stop and escalate to service diagnostics.

When to call service

• The code returns immediately after basic checks
• There are visible signs of damage, overheating, or burning odor
• The code repeats multiple times in a week
• Performance is degraded even after cleaning/ventilation checks
