    I have had a chance to review your suggestions re my HHT-145 problem.
    Your detailed comments refer to Airwatch, which this unit does not have and how to troubleshoot Airwatch. You also include comments saying to "Turn on the air cleaner" . That is my problem, it does not "turn on". You did suggest switching the filters, which I had tried time and time again without success.

    I think I had better look for help somewhere else. Thanks for your trouble.

    The HHT-145 is an oscillating floor standing air purifier from Honeywell. This unit has operated OK for a couple of years and filters have been cleaned as required. At this time the unit is "dead". No lights light, no fan runs, no nothing. Have recleaned the filters, checked to be sure they are installed correctly, have varied the position of the two HEPA filters. Have been sure the top filter actuates the in-the-cabinet switch.
    The current expert focused on the potential for Airwatch problems, but this unit does not, to my knowledge, have Airwatch. It just does not turn on. Haven't gone inside except to remove bottom plate to see if there might be a fuse in the AC supply. None located, but could be there further inside. Something has cut off the power all together.

    Have just replied to the first expert and asked for additional help. Your diagram indicated you know what this unit is . . a floor standing oscillating air purifier. Your suggestions have been tried previously and still don't solve my problem. I submitted additional detail and asked for more help. The thing is just completely dead in the water. No sound, no lights etc. Thanks for your response. Would welcome any more suggestions about known internal problems.

  • Bob Reed Mar 25, 2011

    Hi
    Thank you for your help, but nothing anyone has suggested has resulted in an operational HHT-145. Your suggestions were the most helpful and focused on the problem best. Unfortunately the beast is still dead. I am going to quit for now, but will try to get the payment to go to you.

    Regards, rreed761

    Lots of suggestions, but nothing worked. I am giving up.

Welcome to FixYa!

The air purifier has safety features to ensure that the unit is ready for operation.

  • Check to make sure both HEPA-type filters are installed flush to the air purifier.
  • Check to make sure the rear cover is installed flush with the unit and is locked.

    Here's some additional suggestions:

    1. Check the UV lights under the filters. If they loosen slightly the unit quits working.

    2. Manually press the top filter sensor at the back then turn it on. The sensor plays a major part with regards to turning the unit on. If it's busted, the unit will not turn on.

    3. Blow out the dust inside the unit. Sometimes this helps.

    I hope this will help.

As ridiculous as it sounds, after much electrical troubleshooting my no power problem was fixed after holding in the filter light reset switch again for several seconds.

Check the UV lights under the filters. If they loosen slightly the unit quits working. Unless you need to send the unit for repair. This is a common problem on these units. I wish i could have a better solution.

I have had the same problem. The way I fix mine (it only runs for a couple days straight) is to switch the two filters (or maybe you just need to remove completely?) making sure they are in tight. Replace the cover and it should work!

You can also troubleshoot it..

How to Troubleshoot a Honeywell Air Cleaner

The Honeywell air cleaner serves a very specific function in the household, as far as air quality and circulation. The air cleaning unit has specialized filters that trap minute particles that pass through it, like pet hair, dander, air-borne pollen and bacteria. These ingredients and substances cause allergies and irritation to the nose, throat and lungs, especially in infants and elderly people. The air cleaner can also trap and eliminate odors. Although Honeywell air cleaner units have simple maintenance procedures, to keep them running in satisfactory order the filters and power head should be checked on a regular basis.


things you'll need:

* Honeywell owner's service manual
* Screwdriver
* AAA batteries (if applicable)
* Needle nose pliers
* Ohmmete



Turn the air cleaner switch to the "on" position and activate the blower motor. You should see a neon light illuminate on the on-off system display panel. If your unit has a wall-mounted Airwatch indicator, check to see that the LED light has come on. If the LED lights flash on the Airwatch indicator it means you must replace the two AAA batteries in the back of the case. Check the power cord to the wall if you do not see any lights on the air cleaner display panel.


Turn off the air cleaner. Unscrew the unit from the wall with a screwdriver and pull the case slot back. Remove the old batteries and replace them with two new batteries, but do this within 30 seconds so you don't lose the system memory. Close the case and screw the unit back on the wall. Note that the unit performs a test by flashing and beeping. Hold the black reset on the bottom of the case in for about five seconds. The display will stop flashing and reset.


Turn on the air cleaner and let it run normally, while you monitor the Airwatch indicator. If the indicator begins beeping after 10 minutes and continues to do so, look at the display window for the component that needs attention. Beeping every 10 minutes will indicate a problem with the odor filter, prefilter or the Hepa filter. Clean or change the filters as required by your Honeywell owner's service manual.


Turn off the system blower and then turn it back on after several seconds. This procedure applies if the unit connects to your main heating and air conditioning duct system. You should see the LED light blink off after a few seconds, which indicates the unit has proper voltage. If no LED light illuminates, or the LED light flashes, check the batteries in the Airwatch indicator and ensure that the wall supply cord has a firm connection to the wall socket.


Make sure the inspection panel door shuts firmly to activate the unit, if you have the larger model connected to your heating and air conditioning system. A loose or obstructed door will cut the power supply off from the air cleaner.


Push the test button on the Airwatch indicator. You should hear a snapping sound, which means that the air cleaner cells have been energized. If your unit has a three-speed fan motor, turn on each fan speed and push the test button for each. You should hear snaps for every blower speed.


Turn the air cleaner off. Turn the blower motor off, for the larger unit. Use a screwdriver to remove the front case or open the front access door, if you have the stand-alone unit. Make sure the ionizer wires have their eyelets connected to the upper and lower spring connectors. If one wire has disengaged, use a pair of needle nose pliers to grip the eyelet and reconnect it to the spring end. Replace any bent, crimped or broken ionizer wire.


Look at the small panel on the top of the air cleaner, after removing the cover. You will see three small metal touch plates on the panel. The two outside touch plates will be marked "Collector Terminal", while the middle touch plate will be marked "Ionizer Terminal." Place one lead of an ohmmeter to the outside collector terminal.


Place the other lead to the unit frame, for a metal ground source. The ohm reading should be infinity. Test the other two metal plates with the ohmmeter lead. They should read infinity. If not, the cells have failed.

No power


mine was having the same issue. its been broken for 2 years now. i jsut fixed it a few minutes ago. there is a button sensor behind the top filter. if its not pushed in all the way it wont turn on. my filter was in correctly, but the button doesnt appear to be depressed all the way. when fastening the back cover it locked in good, but was still slightly loose. those two things together means the sensor wasnt being triggered.

with your unit correctly assembled plug it in. while plugged in simply press the top of the back cover (where that sensor is) and the light should go green. i then taped it tight with a thin electrical tape as to not limit the airflow. it now powers on and works great.

hope that solves it for you

According to what I found, if the filter is not reinstalled just right, it won't trigger the filter being back inplace switch.Also, try unplugging the unit for 30 minutes and then plug it back in. That may reset the switch. If tall else fails, call Honeywell Customer Service at 877- 841-2840.

Honeywell htt 011 air filter light won't go off


Thank you to MPODHOLA. After cleaning your Honeywell HHT-011, if the red light does not turn off locate the very small button under the red light. As suggested use a paperclip, hold the button for 5 seconds and this resets the system. Make sure the unit is on when you hold down the button. I tried it with the unit off and it did not work. Turned on the unit, held down the button for 5 seconds and the system reset. No more red light.

Red light won't go off


To RESET the Electronic Filter Check:
When the filter check light remains on,it is time to check/clean the HEPA-Type
filters and reset the filter check,if needed. With the unit powered on,insert the tip of a ball-point pen or
paperclip into the hole next to the LED filter check light and hold for approximately 5 seconds until the
light turns off (Fig 5). Depending upon your individual usage (environment and hours used),you may need
to check and clean the filters more or less frequently. If the HEPA-Type filters are cleaned before the filter
check light turns on,the filter check should be reset at the same time.
These cleaning intervals are intended as guidelines only. Performance of any filter media is dependent
upon the concentration of contaminates going through the system. High concentrations of contaminates
such as dust,pet dander and smoking will reduce the useful performance of the filter.
NOTE:The HEPA-Type filters are not washable.
