I have a Bryant (Model: 396G036075) Gas Furnace. I recently replaced the thermostat with a Rite Temp (Model: GPMG8035C) 7 day programmable thermostat. The furnace blower runs continuously. The furnace still kicks in and warm air emits from the vents until the house reaches the set temperature. However the fan is still running after the furnance acheves the set temperature. It stops blowing warm air and just blows room temperature air thru the house vents. When I first moved into the house there was a manual thermostat installed. I then replaced the manual with a used Rite Temp thermostat that just died. I then just recently purchased a brand new Rite Temp described above. The old Rite Temp thermostat never had this issue. The thermostat fan is set to auto and even if the thermostat is set to off the blower continously runs. Here is what I've tried to fix it:
1) The air filters were dirty so I replaced them with fresh ones.
Powering Furnance OFF steps: turned off the furnace power switch, flipped the furnace breaker to off, set thermostat to off and fan to auto
Powering Furnace ON steps: flipped furnace breaker to on, turn on furnance power switch with the thermostat set to off and fan to auto.
As soon as I power the furnance up the blower starts running and never stops like its supposed to after the house reaches the set temperature.
Do I need to buy another thermostat or is there something faulty on the furnace?
