    bryant furnace start for about 1 minute and then shuts off

    The furnace is over 30 years old and I had a tech out and he said the gas valve has failed. He said the springs inside the valves can fail. The flame sensor was replaced but the unit shuts off about 1 minute after starting.

    I've attached pictures of the unit and it's hard to see the model number but I believe it's 395BAW048095.

    I was told years ago by a tech that gas valves fail closed so I was wondering why the unit would start for a minute and then shut down. I know the unit needs to be replaced but I was hoping to wait until the Spring.

    Do those symptoms sound like a gas valve?

    TIA

    After searching on the net, it looks to be the flame sensor but that was replaced.
    2 different techs said it was the gas valve but I still skeptical.

    All these parts can be easily tested. Flame rod and gas valve included.
