I have a Carrier gas pack. I turned the thermostat to heat. The combustion motor comes on, the ignitor engages, I have 24 volts on the gas valve, but the burners will not ignite. Last season I had the circuit board replaced, the ignitor replaced, and the burners replaced. Seems like I'm not getting gas. After a while of testing I can smell a little gas, but it seems to take a while. Any help would be appreciated. Thanks..
Verify your supply gas pressure with a manometer. If you have gas, and get 24V to the gas valve, then you may have a bad gas valve.
Thanks for the response. Found the problem. Eagwigs blocking the oriface in the gas line. Seems to be working fine now. Glad I could fix it myself with a little help from a phone call to a friend. Thanks again
