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.
