Common Snow Blower Troubleshooting Issues
Even with the best maintenance, snow blowers can still encounter problems, especially when tested during heavy snowfalls. Understanding the most common snow blower troubleshooting issues and how to fix them can save you time and frustration.
1. Engine Won’t Start
A snow blower that won’t start is one of the most frustrating issues, but fortunately, it’s often easy to fix. There are a few common causes behind this problem:
- Fuel issues: Ensure your snow blower has fresh fuel. Gasoline goes stale if left unused for long periods. If you’ve used old fuel, drain the tank and replace it with fresh fuel.
- Spark plug problems: A dirty or worn spark plug can prevent the engine from starting. Remove the spark plug and check for buildup. Clean it with a wire brush or change it if needed.
- Choke position: Double-check that the choke is in the correct position. If the choke is stuck or improperly set, the engine may not start.
- Fuel shutoff valve: If your snow blower has a fuel shutoff valve, ensure it’s in the “on” position.
If you’ve checked all these factors and the engine still won’t start, it may be time to consult a professional for further diagnosis.
2. Snow Blower Won’t Throw Snow
One of the key functions of a snow blower is its ability to throw snow. If your snow blower isn’t doing this effectively, there are a few things to check:
- Clogged auger or chute: Snow can build up inside the auger or chute, causing a blockage. Turn off the snow blower, then clear out any snow or debris clogging the system.
- Broken or worn auger belt: The auger belt turns the auger blades. If it is loose, broken, or worn, it won’t be able to move the snow effectively. Inspect the belt and replace it if needed.
- Frozen or damaged impeller: It can’t correctly expel snow if frozen or damaged. Ensure the impeller is debris-free, and check if it’s working correctly.
By checking these components and ensuring they’re clear and functioning, you can return your snow blower to throwing snow as it should.
3. Uneven Snow Clearing
If your snow blower is only clearing snow in some areas and leaving snow behind, the problem may lie with the drive or auger system:
- Auger imbalance: An unbalanced or damaged auger can cause uneven snow clearing. Inspect the auger blades for damage or wear. Replace any damaged blades to restore smooth operation.
- Drive system issues: If the wheels or tracks aren’t moving evenly, it can lead to uneven snow clearing. Check the tire pressure or inspect the tracks for damage. Lubricating the drive system might also help resolve this issue.
- Improper height adjustment: Check that the snow blower’s skids are properly adjusted. If they’re too high, the snow blower won’t be able to pick up snow effectively, especially on uneven surfaces.
4. Snow Blower is Stalling
If your snow blower stalls during operation, it may be due to fuel or air system problems:
- Dirty air filter: A clogged filter restricts airflow to the engine, causing it to stall. Clean or replace the air filter as needed to ensure proper engine performance.
- Fuel delivery issues: If your fuel lines or carburetor are clogged, it can cause the engine to stall. Clean the carburetor and inspect the fuel lines for blockages.
- Low oil levels: Low oil levels can make the engine stall. Check the oil levels and top them off if necessary.
Addressing these potential issues can prevent your snow blower from stalling mid-operation.
5. Loss of Power
If your snow blower is losing power, it may be working harder than it should due to the following:
- Clogged intake or exhaust: Make sure the intake and exhaust are free from blockages. Snow, dirt, and debris can sometimes get lodged in these areas, restricting airflow and causing a loss of power.
- Worn belts or pulleys: Check the belts and pulleys for wear. A worn or slipping belt can reduce the power transferred from the engine to the auger and drive system.
Maintaining clean air and exhaust systems and inspecting the belts will help restore your snow blower’s power so it can operate at full capacity.
