It's a cheap bestech thermostat...I have changed batteries...reset thermostat....taken it off wall and reset completely....just flashes cool over 30 minutes now
HVAC Technician: airheatman, HVAC Technician replied 10 months ago

Did you reset using a paper clip or something through hole in front

Customer reply replied 10 months ago
use a pin and I also removed from wall and let go blank with no batteries to fully reset, then reinstalled....done this twice already
HVAC Technician: airheatman, HVAC Technician replied 10 months ago

Sounds like you may need to replace stat.Just turning off should not cause this.
