did you ever solve this issue? I just borrowed my mom's and it worked fine for two days and then suddenly won't turn on at all. I wonder if there is a fuse that might have blown during a power surge while we were out of town or something...
Any help would be appreciated.

SOURCE: my honeywell air purifier is emmiting an awful

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...

SOURCE: honeywell air purifier, will not turn on,

Does this unit have a 3 volt battery in the control panel like the 17005 model? The battery lasts appx 4-5 years then the unit doesnt seem to work any more once you change it. The unit must be left plugged in while you change the battery otherwise you lose your programing. If your not under warranty, UNPLUG it then pull out the filter, take out the 6 screws, separate the sides, and expose the fan. If the fan does not spin very easilly with no drag, the bearings are gummy; which is why nearly all small motors get replaced. The motor can be easilly disassembled, gummy grease washed off with rubbing alcohol and a cotton swab, and reoiled with synthetic oil. These units are designed to gum up and require replacement at approximately the same time the warranty expires. They would last almost indefinitely if oiled in their little oil ports occasionally (every couple of years). If your bearings are stiff, then a hidden safety device has tripped to avoid a fire, and if you are handy, you can replace the blown fuse if you can locate it on the circuit board, or the blown over temp device. If you have to pay some one to do this, it is cheaper to replace the whole machine in this throw away world.

Why doesn't the fan engage? The filters are perfectly clean and it receives power


See if the motor is bound up. Move the fan blade to check for stiffness. The motor may just need a drop of oil. There is an internal fuse in the motor that you cannot change It may have opened. If you have access to a volt meter check all the wires on the power switch

Environizer doesn't work


Is it dead? does the motor run? Fan blow? No freshened smell from unit, only stale odor? You haven't given any usable info here but I'll address a dead unit condition for you: power cord stretched/damaged, on/off switch bad, fuse/cicuit breaker(if any are used).

GE Adora microwave worked 20 minutes ago. Now, totally dead. The lights, fans, turntable motor, microwave cooking elements, nothing.. works. AC power to the outlet is just fine.


Sometimes if a lot of steam has been produced while cooking, water may collect under the turntable plate and run down the spindle into the turntable motor. This can short circuit the motor and it will take the fuse out with it.
The fuse is usually housed in a plastic tubular case about 2inches long. Split the tube apart and replace the fuse if necessary (it's something silly like about 7000 volts). Switch on and check to see if anything else is not working like the turntable, lights, or fan etc and replace as necessary.

Fan is not coming on


The motor spins on brass bushings. you can try oiling the brass bushing. take off the front grill then gently pull off the fan blades. you need to oil the motor center shaft lay it on its back so the oil will run down into the bushing(not to much and use a light oil). there is one on the back of the motor also, this one is a little harder to get too. if this dont work you need a new motor. you can get on off of ebay cheaper. the motor should be replaced by some kind of tech savey person, as the are delicate and a very specifice disassemble procedure.

The Intelli-Check™ Filter Monitors will indicate replacement of the pre-filter and the

HEPA filter. Depending upon your individual usage (environment and hours used),

you may need to check and replace the filters more or less frequently.

To check Expected Filter Life Usage

When the unit is turned on, quickly press the appropriate filter monitor button. The

pre-filter light will flash up to 3 times and the HEPA filter light will flash up to 4 times,

depending upon how much expected filter life has been used.

PREFILTER:

1 flash = from new, up to 1/3 expected life used up

2 flashes = between 1/3 and 2/3 expected life used up

3 flashes = between 2/3 and all of expected life used up

Remains on = time to check/replace pre-filter

HEPA FILTER:

1 flash = from new, up to 1/4 expected life used up

2 flashes = between 1/4 and 1/2 expected life used up

3 flashes = between 1/2 and 3/4 expected life used up

4 flashes = between 3/4 and all of expected life used up

Remains on = time to check/replace HEPA filter

To RESET Filter Monitor

When the filter monitor light remains on, it is time to check/replace the filter and reset

the filter monitor, if needed. With the unit powered on, press and hold the appropriate

filter monitor button down for approximately 5 seconds until the light turns off.
Depending upon your individual usage (environment and hours

We have model 11502 air purifier. Recently turned it on and it ran for a few minutes and then stopped. Motor sounded fine- no squealing, didn't slow down before it went off- just stopped like it was...


Yes there is a thermal cutoff that will shut the motor off for a period of time to protect it from getting to hot. If this is what happened after 20-30 mins. the motor should come back on and run again. If it does I would try to clean motor as best I could using a soft brush, vacumn, and blow out with air if possible. Clean fan of f as best you can to help motor run cooler.Hope this helps.Thank you

Fan blade barely rotates when turned on high.


there may be a problem with fan motor,but i believe your problem may be the rotory switch that controlls voltage to fan motor,to check this pull knobs off front ,then remove filter from back,there are 4 screws in bottom of case remove these,pull unit out carefully .there are 5 wires conected to unit ,two for fan 2 for on off switch,1 for ground just what wires go were,then disconnect wires from there posts,and pull unit out of box,find the two wires that go fan,snip wires that go to the circiut board leaving enough space to rewire after test get extention cord and snip off to make direct plug to fan to wall connect extention to the two wires from the fan motor and wire nut or tape so no short,pug extention cord into wall outlet if fan runs on a high rpm or max power,then your rotory switch is no good and you can install an external rotory switch on side of unit,if fan does not run any faster then your fan motor needs replaced,let me no if you need more help
