how to tell if an ignition control module is bad
new Igniter was not getting 110v from the ignition control module (fenwal 2465H 600-003 or 35-655-600-003). When the call to heat comes, the motor runs. There is supposed to be 110v from control module to igniter (which I measured once when it was working) but it is not there. After 45 seconds there is a 24v to gas valve and a click. The valve opens but since there is no flame, it is then 0v and shuts off. During the whole time, the red diagnostic light stays on. According to the spec, this is supposed to be "Internal Control Failure". Does it mean this control module is bad? Thanks!
