Honeywell Furnace Air Filter clicking noise after cleaning it

Ignore the lights. Wash the outer foam filter every two months. As long as air is going through the inner filter does not need to be changed. Blow the inner filter out FROM THE INSIDE with your vacuum cleaner. (blow air the opposite direction of air flow to get the nasty stuff off.)

I hope I helped you 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.

Yes you can run the furnace with out the electronic air cleaner for awhile.... It you are in a very dusty conditions than I would not run it very long a day or two....because you will not have any protection for dirty getting stuck on the evaporator coil or if you have a 90% gas furnace the secondary heat exchanger...and restricting air flow.... You can put in a 1" pleated air filter the same size as the total of the two cells in place of the cells till you can get the electronic working..... Sounds like either something big is caught across the cell plate or they are still wet and have not dryed out completely. Hope this helps.

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.

Neon light on air cleaner does not come on
1. Make sure the furnace or air conditioner fan is running.
2. Make sure the access door is firmly closed.
3. Make sure the On-Off switch is in the On position.
4. On models without the Solid State Performance Indicator, if the electronic cell(s)
are wet, check again in two to three hours.

It is normal to hear occasional snapping from your Electronic Air Cleaner. This occurs when larger particles are caught by the ionizer wires. Continuous snapping is not normal however, and should be investigated as outlined below: Please note that the metal electronic cells may have some sharp edges; use care when handling the cells. Wear gloves to protect your hands from being cut if needed. Remove both electronic cells. Make sure that there is no hair, dirt, sand or any debris on the bottom inside the Electronic air cleaner. If there is, remove what you can by hand. If a lot of debris is left in bottom of the Air Cleaner, you may want to use a vacuum attachment to see if you can vacuum up what you can. Do not vacuum the Pre-filter or Post filter this may damage it. Close the access door, and then turn on the Electronic Air Cleaner and the system fan. If the snapping continues with the cells removed, contact your heating and cooling contractor for service on the unit and turn off the Electronic Air Cleaner’s power. If snapping does not continue, make sure the electronic cells are clean, dry and properly installed. Inspect the electronic cells for bent collector plates, broken wires between the plates, dirt on the insulators, and damaged collector contact tabs located on the top of the cells. Make sure the pre-filters are in good condition and are in the cabinet slot farthest from the furnace (The order of the Electronic Air Cleaner Filters are from the return duct to the furnace is: Pre-Filter, electronic cell, and then Post filter, if your Electronic Air Cleaner has one). If the snapping persists and you are unable to locate any physical cause, please contact your heating and cooling contractor for service on the unit and turn off power to the Electronic Air Cleaner.

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.
