I have a TH6320R thermostat that has been working

Customer Question

I have a TH6320R thermostat that has been working perfectly for 8 or 9 years. I turned the power of to replace a heat duct blower fan, turned power back on, and now can not get thermostat to reconnect. The green light will flash but after a while, a few hours, no more flashing green light, and still no connection. HELP ***********
