What Should I Do If My Generator Emits a Strange Smell?

April 5, 2026

Quick Answer

STRANGE SMELL FROM GENERATOR: Shut down the generator immediately and move to a well-ventilated area to avoid potential carbon monoxide poisoning. Never ignore the smell, as it may indicate a serious safety issue.

Identify the Possible Causes

If your generator emits a strange smell, it could be due to several reasons. One common cause is the buildup of carbon monoxide from incomplete combustion of fuel. This is often seen in generators with faulty or clogged air filters, or those not properly maintained. Another possible cause is the burning of gasoline or oil, which can produce a strong, unpleasant odor.

Safety Precautions and Checks

To ensure your safety, immediately turn off the generator and move to a well-ventilated area. Do not attempt to investigate the source of the smell while the generator is still running. Check the air filter for any blockages or damage, and clean or replace it as needed. Also, inspect the exhaust system for any signs of blockage or damage. Consider using a carbon monoxide detector in the vicinity of the generator to alert you to potential carbon monoxide buildup.

Troubleshooting and Maintenance

Regular maintenance is crucial to prevent generator breakdowns and potential safety hazards. Check the fuel level, oil level, and air filter before each use. Ensure the generator is properly installed and levelled to prevent oil leaks and other issues. If the smell persists after checking the air filter and exhaust system, it may be necessary to consult a professional for further diagnosis and repair. Always follow the manufacturer’s instructions for maintenance and troubleshooting.
