This particular ignition control is obsolete by the manufacturer, it utilizes a radiant sensor to verify ignitor warm up and to verify ignition- very similar to a flame sensor used on a gas dryer except it has NO(normally open) contacts and NC(normally closed)contacts. Don't even ask why they used this setup when a bettter mouse trap was already available.
That being said, check the terminals to the radiant sensor. The one I just worked on had one of the terminals break off of the sensor itself. It is located below the ignitor and is a 2 x 3 square black box. Looks like(I can't see the diagram too clearly) Black to Pink is NC and Black to Brown is NO. When the ignitior turns off the NO contacts close and NC contacts open. The ICP part number to the sensor is 1009948, and no it doesn't come up on the repairclinic.com site.
White-Rodgers couldn't give me any information on the gas valve or control. ICP didn't provide me with much other than the fact it is obsolete and there is an update kit available - (converts the control system to flame rectification complete with a new control and wiring harnesses & burner cover). The part number is 1011671 and runs around $220.00 at a wholesale supplier.
As for checking just the gas valve I couldn't identify one terminal from the next and went through every White-Rodgers gas valve wiring diagram I could find with no success. Again it is specific to this control but will work with the upgrade kit.
Hope this helps
