Ariens Snow Blower Won't Start? 5 Common Fixes from Your Cheshire Service Center

Published October 30, 2025

It's the scenario every Berkshire County homeowner dreads: snow is piling up, and your trusted Ariens snow blower won't start. Don't panic! Many no-start issues are simple to fix, while others indicate a problem that requires professional attention.

At H.D. Reynolds Equipment in Cheshire, MA, we service more Ariens blowers than anyone in the region. Here are the top 5 problems we see and what you can do before scheduling a service appointment.

1. The #1 Problem: Fuel Issues ("Won't Start")

More than 80% of starting problems are related to bad gas or a clogged fuel system.

• The Cause: Ethanol in gasoline breaks down and gums up the small passages in the carburetor, especially after sitting over the summer.
• The Quick Fix: Drain the tank and refill with fresh, high-octane, ethanol-free gasoline mixed with the correct fuel stabilizer. Check that your fuel cap vent is not blocked.
• The Service Push: If fresh fuel doesn't work after a few pulls, the carburetor jet is clogged. Stop! Running it can cause damage. Bring it to H.D. Reynolds for a professional carb cleaning or replacement.

2. Problem 2: Auger or Impeller Not Turning

If the engine runs but the snow isn't being moved, a critical safety component has done its job.

• The Cause: A broken shear pin. These small bolts are designed to snap when the auger hits a rock, ice chunk, or foreign object, protecting the expensive gearbox from damage.
• The Quick Fix: Locate the broken pin (usually near the gearbox or on the auger shaft). Remove the old pieces and replace it with a genuine Ariens factory shear pin.
• The Service Push: If the shear pins are intact, the problem is likely a broken drive belt. This replacement involves removing covers and accurately tensioning the belt—a job best handled by our certified technicians.

3. Problem 3: Engine Surges or Runs Rough

This is a sign the fuel-air mixture is inconsistent.

• The Cause: A partially clogged carburetor or a dirty spark plug that is misfiring.
• The Quick Fix: Replace the spark plug and check your fuel. Run the engine for a few minutes to warm it up.
• The Service Push: If the surging persists, the main jet in the carburetor is partially restricted. This requires professional ultrasonic cleaning or replacement to restore smooth engine operation and prevent long-term damage.

4. Problem 4: Not Throwing Snow Far

If the engine sounds fine but the snow is just dribbling out of the chute, the impeller isn't getting enough snow.

• The Cause: Worn-out scraper bar or skid shoes.
• The Quick Fix: Inspect the underside. If the scraper bar is worn down, it leaves a layer of snow behind, preventing the auger from properly "feeding" the impeller. Skid shoes can often be flipped to extend their life.
• The Service Push: We keep Ariens OEM scraper bars and skid shoes in stock. Bring your blower in for replacement and adjustment to maximize your throwing distance this season.
