If a generator is covered in snow, it risks overheating, choking, or failing to start due to blocked air intakes, clogged filters, and restricted exhaust, which prevents necessary airflow and cooling, while ice can freeze components or panels shut, leading to damage or dangerous carbon monoxide buildup if the exhaust is blocked.
You must clear snow and ice from around the unit and its vents, ensuring at least a few feet of clearance and proper exhaust ventilation to keep it running safely.
Dangers of Snow & Ice on Generators
Overheating & Shutdowns: Snow blocking air intakes or cooling vents reduces airflow, causing the engine to work harder, overheat, and potentially shut down automatically.
Engine Choking: Snow getting sucked into the air filter can soak it, making the engine "choke" and perform poorly.
Starting Problems: Cold weather and ice can drain batteries and stiffen moving parts, making startup difficult, especially if vents are blocked.
Carbon Monoxide Hazard: If snow blocks the exhaust, deadly carbon monoxide gas can back up and seep into your home, especially if the unit is under an overhang.
Damage: Ice can freeze control panels or access doors shut, making servicing impossible and potentially causing damage.
How to Protect Your Generator
Clear Snow: Shovel a 2-3 foot perimeter around the unit and clear all snow and ice off the top and vents.
Elevate: Install the generator on a raised platform (like a concrete pad) to prevent snow buildup.
Ensure Airflow: Use PVC pipes or strategically placed barriers (not a full enclosure) to direct intake and exhaust airflow safely away from drifting snow.
Use Proper Covers: If using a shelter, ensure it's extremely well-ventilated and designed for use during operation, like a GenTent, to prevent overheating.
Check Vents: Make sure nothing, including leaves or snow, blocks the air intake or exhaust outlet.
