Fujitsu Fan Motor
Replacing a fan motor is a good and affordable measure to maintain good operating conditions for your heat pump. A whistling or howling from your heat pump can mean that the fan motor bearings have become worn out.
There are fan motors in both the indoor and outdoor part, but perhaps it is most common for the outdoor fan to give up first.

GUIDE-How to replace the Fan motor on your air / air outdoor unit
A few things to keep in mind before you start installing the Fan Motor
* Turn off the electricity completely, preferably from the plug cabinet.
* Before removing the old motor, make sure that the replacement motor and connectors are identical to the old one.
Not all installations are done in the exact same way, but to a large extent. There are many manufacturers of fan motors, some of the largest are for example: IVT, Canvac, Daikin, Mitsubishi Electric and many more.
Estimated time: 1h
What do you need: Screwdriver, Tip bar, Socket wrench 8mm
Start by unscrewing the front, grille and lift off the lid, use a screwdriver.
When the grille is gone, unscrew the screw located in the middle of the fan using an 8mm socket wrench, then remove the fan from the motor. If the fan is stuck, you can try spraying some 5-56 on it.
There are 4 screws on the fan motor that must be removed before you can remove it.
Disconnect the cable connected to the motor, follow the cable and see where it leads. Disconnect and unplug the cable together with the fan motor using a tip rod. A tip is that you take a photo of how the cable sits to be able to look back at when the new cable is to be connected.
Now that the old motor is disconnected, it is time to insert the new one, screw on the new motor in the same way as you removed it. Route the new cable the same way you removed it and connect it in the same place as the previous cable.
Now it's time to put the fan back on, do not forget the screw in the middle.
When the front and the grille are still gone, it is a good idea to remove any dirt that may be there.
Replace the front and grille and cover with all screws
Turn on the power again and you're done!
