I have Bryant Plus 90t Gas Furnace, Model # 352AAV036080, Series A, Manufacture Date 2007,
My quistion is "HOW TO FIX BLOWER FAN NOT TURNING OFF"
HERE ARE THE DETAILS: my thermostat set to 20'C, the FAN was set to "AUTO", and HEAT "ON". we where out to grocery store and when we came back we feel so hot inside the house. i check the thermostat it was set to 20'C and the temperature inside was 25'C and the furnace keep running...
I set the thermostat to heat OFF and the furnace stop. but i notice the fan still running all the time.. I try to set fan ON or AUTO its running all the time.
So I call the Gas Emergency Service in the city and they check... . The service guy said my furnace has no problem..and he said thermostat has a problem.... he told me to call a sevice contactor to replace the thermostat.. and he walked away because its just a free service of the city.. So I didn't call a service contactor. i did go to home depot and buy a new thermostat, i open it, follow the instruction inside and replace it by my self.. turn on the power back with a new thermostat and its working. the furnace stop when it reach the set temperature... but i notice again the blower fan still running all the time.it only stop if i switch OFF the power at the furnace. should be auto off when it reach the set temperature.. ANY HELPFULL ADVISE will be apreciated
THANK YOU IN ADVANCE>>
