Take out the cells, they weigh about 8 pounds apiece. Make sure you remove both. Put the door back on and turn the fan in the furnace on. IF the light on the power supply comes on, then the power head is most likely good.

Then insert one cell at a time, individually. Push the single cell in all the way to the back, put the door back on, if the light is on, that cell is fine. If the cell does not come on, there is most likely a bent fin on the cell. simply bend the fin so it does not touch the other fins and you should be fine. Repeat this step on the other cell.

Make sure the door to the filter is closed, the power switch is on and the furnace fan is on.

Good luck.

I have had this model air cleaner for years, and find that the cells have to be aligned "just right" to make contact and allow power through. Make sure the contact points at the edge of the cells are not dirty (use fine sandpaper or emory cloth) and re-seating them in the unit several times may be necessary.

Changed filter and pre filter both lights continue to blink, not resetting

Hello, this is Ava with Think Crucial.

Make sure that the new filters you installed are undamaged and correctly seated in it's assembly. When resetting the unit, unit must be powered on then press and hold the appropriate filter indicator button for approximately 10 seconds until the light turns off. If nothings happens, unplugged the unit from the power for about a minute and then try to reset the unit. If all else fails, I would suggest to contact Honeywell for more assistance.

Can somebody help fix the problem I'm having with my Honeywell air purifier....when I press power button it won't work all I see is red light any button I press red it wont do anything....pls!!!!.....

I have the same unit.
Have you cleaned out the removable filters?
also the red light at the bottom indicates the time to clean the filters.
to reset it, use a paper clip. The red light on the bottom right is the filter indicator light, what looks like it should be a light beside that filter light, is actually a reset button, just poke it with a paper clip for a few seconds to reset. The bottom red light goes out

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

CLEANED FILTER. PUT THE FILTER BACK IN AND NOW IT IS MAKING A CLICKING NOISE. TOOK THE VACUM TO THE FILTER AND IT IS STILL MAKING THE NOISE

The clicking noise is the sound of the high ionizing voltage 'shorting' due to dirt or humidity or both which provides the pathway for discharge. Cleaning and completely drying the filter(s) does not always help, in this case switching the unit to a lower operational speed can mitigate this problem. New filter(s) may be needed to resolve the clicking.

F50 air cleaner cells inoperative

Check for any of the metal layers in the cell to be touching or too close together. These units are very expensive to repair and to be honest the best option is to find a disposable box filter that will fill the hole.

Kaz Honeywell Tower Air filter rest light

When the filter monitor light remains on, it is time to check/clean the IFD™ filters and reset the filter
monitor, if needed. With the unit powered on, insert the tip of a ball-point pen or paperclip next to the LED
filter check light and hold for approximately 5 seconds until the light turns off (Fig. 3). Depending upon
your individual usage (environment and hours used), you may need to check and clean the filters more or
less frequently. If the IFD™ filters are cleaned before the filter monitor light turns on, the filter monitor
should be reset at the same time.
