8 year old Bryant furnace the pilot gets blown out at ignition (when the fire moves and blows itself out). Service technician does not know why since the furnace is clean and pilot is strong. He installed a reignitor near the pilot so it reignites the pilot when it is off. The reignitor works somewhat but when the fire goes out a few times then the temperature at the sensor decrease and shuts off the gas.
What is the reason for the unstable initial fire? Is there a solution to this?
Thanks.
