My Honeywell HFD-120 Air Purifier rattles when it is on, I have pulled out the filters and turned it on, the noise is coming from where the motor is, do you know how I can fix this problem, I have only had it for about 4 months

SOURCE: Lost the manual on my Honeywell HFD 110

Found the manual - take my question off this site.

Mine quit too... The led screen went blank so I changed the battery. Now it does nothing. I totally disassembled it as the fan was turning stiffly.(should spin very easilly) The grease in the end bearing was stiff. I washed the gummy grease off the shaft and reoiled with synthetic oil. Your smell is probably motor windings overheating. I disassembled the electronic control and was disgusted to see that there is a glass fuse soldered to the circuit board. I believe the only reason for this fuse is to cause us consumers to needlessly replace otherwise good equipment. (It cost more to pay a repairman to replace the hidden fuse than to purchase a new unit)The fuse is not blown. At least this fuse actually looks lide a fuse unlife the stealth fuses most electronics have hidden in them. I can not obtain a wireing diagram on my 17005 unit but it has a black box inside behind the control panel. It looks like a small start capacitor, but it has a temp rating on it of 70*C. I suspicion it is a single use over heat safety which triggered when my motor got hot due to stiff bearings. I refuse to play their game and purchase a new air cleaner. I love this one... So, if I can not determine what that little black box is, I am going to bypass all the crappy electronics and just drill a hole on top by the handle and install a hi/lo/off manual switch directly to the motors wire hasness. This machine will never give me problems ever again, and if I oil the motor every couple of years with synthetic (Ander oil) this unit WILL last me for the rest of my life...
