    Reset honeywell rth230b after changing filter
    Is there a reset for the rth230b honeywell thermostat? Filter light began flashing and the blower stopped, changed the filter but nothing blowing out. Fan is running on compressor.

    Possibly kill the power to the airhandler/furnace for about 10 seconds and turn back on,, should reset

    Looked up the installation and user guide: 3.6 Filter Replacement Indicator
    After 500 hours of operation, an icon appears to indicate
    That the filter needs replacement. Once the filter
    Is replaced, press [ Filter ] for 3 seconds to remove
    The icon and reset the counter.
