Carrier Natural Gas Furnace main gas valve will not open every call for heat
We have a Carrier Weather Maker 8000 Natural Gas Furnace not functioning properly. We have replaced pressure switch, hot surface ignitor, flame sensor and control board. It will cycle 3 to 4 times and then not come back on. Is it possibly a bad coil on gas valve?:rolleyes:

Are you familiar with the normal operating sequence? If you observe that the inducer is running and the ignitor is glowing, but ignition does not occur, the gas control is a possibility. Do you notice any "clicking" coming from the gas control? Weathermaker 8000 is just a model name - can you locate and post the actual, complete model # ? You will find it on a label inside the unit.
