How To Repair Leaf Blower That Will Not Blow Air

Blower Fan

If your blower is not blowing air as it normally would but the engine is running without any noticeable issues, it is likely that the blowers fan is broken. A broken fan will not create the proper suction that the unit needs to blow air with consistent force. To inspect and replace a broken fan, unscrew the fan housing from the side of the blower. If the fan is loose, it may simply need to be tightened. If the fan is broken or damaged, remove the spark plug boot and spark plug and feed a piece of rope into the spark plug hole to stop the piston from rotating inside of the cylinder while the fan is unscrewed. Once the old blade is removed, replace it with a new blade.
