Holmes HEH8031 Fan Blade Assembly Replacement

はじめに

Use this repair if you want to replace your fan blade assembly. Be sure to turn off the power and unplug the heater before beginning to change the fan assembly. The screws in this heater are recessed, so using a magnetic screwdriver will be helpful. Note: When reassembling the unit, you must replace the 2 machine screws that connect the rotor assembly to the housing before replacing the coarse-threaded screws. Aligning the machine screws may take some finesse.
