January 30, 2026: A Generac 22 KW automatic standby generator, model 0065520, reportedly experienced severe surging during a recent four-day power outage caused by a snowstorm. The issue was traced to the air filter becoming clogged with snow and ice, leading to concerns about incomplete fuel combustion and the emission of carbon monoxide. While the consumer in this incident did not suffer poisoning, the potential for this dangerous gas to be produced highlights a critical safety risk.

Incident Overview
On November 30, 2025, a heavy snowstorm led to a widespread power outage that lasted for four days. The consumer’s Generac 22 KW automatic standby generator, model 0065520, serial # 9650633, activated as designed to provide emergency power. However, after several hours of operation, the generator began to surge, rapidly speeding up and slowing down. Upon investigation, the owners discovered that the generator’s air filter was significantly clogged with snow and ice. The consumer expresses concern that this condition, which impedes proper air intake, could lead to incomplete combustion of the LP (liquid propane) fuel, subsequently emitting hazardous carbon monoxide. Although the family was not poisoned, they reported hearing of other similar incidents in their area during the same storm. The consumer attributes the issue to a potential design flaw that allows snow to enter the air filter, creating a dangerous operating condition.
Safety Concerns
The incident involving the Generac generator raises several serious safety concerns:
- Carbon Monoxide Poisoning: The primary and most immediate danger is the potential for carbon monoxide (CO) poisoning. When a generator’s air filter is obstructed, it can lead to incomplete combustion of the fuel. Incomplete combustion produces carbon monoxide, an odorless, colorless, and highly toxic gas that can be fatal if inhaled. Even in lower concentrations, CO exposure can cause headaches, dizziness, nausea, and disorientation, which can be particularly dangerous during a power outage when vigilance might be lowered.
- Design Flaw: The consumer’s observation that snow and ice can enter and clog the air filter points to a potential design vulnerability. Standby generators are specifically designed to operate in adverse weather conditions, including snowstorms. A design that allows weather elements to compromise a critical component like the air filter poses a significant safety risk during the very conditions for which the product is intended.
- Generator Malfunction and Damage: Surging indicates the generator is struggling to maintain proper operation. This not only points to a potential CO risk but can also cause accelerated wear and tear on the generator’s engine, potentially leading to premature failure or costly repairs.
- Who Might Be Affected: Anyone in the vicinity of a malfunctioning generator, including residents, neighbors, and emergency personnel, could be affected by carbon monoxide emissions. Individuals in enclosed or poorly ventilated spaces are at the highest risk.
- Property Damage Potential: While not directly reported in this incident, an improperly functioning generator could potentially lead to electrical system damage or, in extreme cases, fire if other components overheat due to strain or if fuel is not properly managed.
What Consumers Should Do
Consumers who own Generac standby generators, particularly model 0065520, should take the following precautions:
- Install Carbon Monoxide Detectors: Ensure you have working carbon monoxide detectors installed inside your home, especially near sleeping areas. Test them regularly and replace batteries as needed. This is your first line of defense against CO poisoning.
- Regular Inspections, Especially During Winter: Periodically inspect your generator, particularly before and during inclement weather conditions, especially snowstorms. Check the air intake and filter areas for any obstructions, including snow, ice, leaves, or debris.
- Clear Snow and Ice: If snow and ice accumulate around your generator, carefully clear it away from all vents, exhausts, and air intake areas to ensure proper airflow and prevent filter clogging.
- Professional Maintenance: Schedule regular professional maintenance for your standby generator to ensure it is operating correctly and efficiently. Technicians can identify potential issues, including vulnerabilities to weather elements.
- Observe Generator Operation: Pay attention to any unusual sounds or operational patterns from your generator, such as surging (speeding up and slowing down rapidly). If you notice such behavior, shut down the generator safely and investigate the cause.
- Report Incidents: If you experience a similar issue or any safety concern with your generator, report it immediately to the manufacturer and the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report helps identify patterns and prompt corrective actions.
- Review Manual: Consult your generator’s owner’s manual for specific guidelines on operation in severe weather and maintenance procedures.
