Have a carrier 58RAV. It was just running the blower constantly, per troubleshooting I replaced the board. Now everything runs during the test cycle but when after hot start ignitor glows and my volt meter starts to read volts going to the gas valve I hear a click and the hot surface ignitor and power to gas valve both shut off, then it all starts over again.

Not getting any flash code on the system light. Tried taping the gas valve.

Any ideas? Is there something other than the gas valve that could be causing the system to abort or shut down like that?
