Furnace Gas Valve Problem?


About every 2 days my Bryant furnace fails to respond to the thermostats call for heat. If I disconnect the wires to the gas valve (coming from the control board), then reconnect them, the furnace lights up and works perfectlly for a day or two. At that point I have to repeat the procedure to get the unit to work again. Shutting the 110v feed off, then on, has no effect. The control board is new. I'd be grateful if someone would tell me what is going on and how to fix it.

What kind of pilot it has? Is it standing , spark, or glow. If its spark bimetal pilot. You will need to clean that metal part were the flame from the pilot its. Also clean pilot too.

It's a hot surface ignition system.

The flame sensor and control board are brand new. The ground connections are solid. I'm thinking, at this point, that I should replace the ignitor and if that doesn't fix the problem, it's likely the gas valve. Is my thinking logical?
