Leaf blower faults: impeller, bag and battery

BLOWERS & VACUUMS

Loss of air is not a weak engine. It is the impeller.

A blower moves air with a plastic wheel spinning very fast. Everything that goes wrong with it happens at that wheel or on the way to it.

SPARE PARTS, WITH THE MAKER’S OWN CODE

Replacement parts

These rows come from the manufacturer’s own parts pages, read on Husqvarna, Patriot Products, STIHL. The code is the one you order by. The price is the maker’s list price on the day we read it — shops sell for less, which is what the buttons are for.

BUY

Repair it, or replace it

The whole machine

An impeller is a cheap part and restores the machine completely. A cracked fan housing on a handheld is where it ends. Both new and used open in the shop for your country.

FAULTS

Blowers & vacuums: the failures that repeat

Leaves pack behind the impeller and unbalance it. Vacuum bags clog at the zip, not at the mouth. On battery machines the pack loosens under vibration and cuts out under load while reading full at rest.

Written by the TroubleAtlas technical team from the manuals listed at the foot of this page. Where a maker documents a fault, we quote the maker.

What the maker sells as a replacement

Not “the most common failures” — nobody publishes that honestly. This is what Husqvarna, Patriot Products, STIHL stocks as a spare for these machines, fasteners excluded.
