Overheating is one of the common issues of the leaf blower. This problem decreases work efficiency as the machine completely shuts down or needs time to cool off. The work that could be done in one go gets divided into several.

  • To fix the overheating issue, take a pack of the heat sink. The one preferable to the Ryobi 4-Cycle leaf blower is 28mm * 28mm * 8mm.
  • Next, get thermal glue. If you face trouble finding the glue, ask for the ones car enthusiasts use to fasten on their controllers.
  • Glue one of the heat sink to the smoother surface of the controller that is on the opposite of the fan.

Through this technique, you will get relief from overheating issues. You can complete your yard work in one go. There is another way to fix the overheating issue. Sometimes what happens is the controller inside the machine gets overheated.

The motor inside the machine has a fan attached at its end. The fan blows air into the motor, so it doesn’t let it overheat. It cools the windings in the motor.

Though the fan cannot do all the work. The controller remains beside the motor, which manages all the functions of the motor.

So you can install another fan on the backside of the motor, so the controller cools down too. This way, the overheating issue can be avoided.

How to Replace Fan Blade

Sometimes the blower doesn’t start due to a faulty or age-old clogging fan on the motor. So, it is necessary to install a new. We have discussed the procedure to install a new fan here.

  • First, take off all the screws and take the leaf blower apart.
  • After all the screws have been taken apart, move the handle switch.
  • Detach the shaft from the motor housing. Then slide the shaft out of the housing and set it aside.
  • You will see the fan when the shaft is detached. Take a ratchet with a ½’’ socket to remove the nut. Turn it in the clockwise direction to remove the nut after removing the fan, and screw the nut back for the new one’s installation.
  • After you have secured the new fan, slide the shaft back into the motor housing. Then screw back all the screws in their respective location.
