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.
