It runs, but isn’t clearing the snow properly
The engine sounds normal, but you’re leaving snow behind. Where that happens helps narrow the question: across the whole clearing width, on one side, or in a chute that keeps filling up.
Where the snow stops clearing
Getting snow throughThe engine sounds normal, but less snow comes out
Less snow is coming out even though the engine sounds normal. Compare the change with previous use and note whether both sides still clear.
Getting snow throughOnly one side is clearing the snow
When only one side of the snowblower clears, report which side changed and whether it followed an impact. Parts decisions depend on the model.
Getting snow throughThe chute keeps packing up during use
A chute that keeps packing up needs the correct shutdown instructions first. Describe the repeated blockage and the snow without recreating it.
