The purge motor spins up, and I have vacuum, but the ignitor (ceramic hot surface type) won't fire up. I've got 3 blinking lights which indicate an open. I would think that I should check the voltage on the igniter but I'm not certain what it should be.

I don't detect voltage on the leads from the module toward the ignitor at any point during the purge cycle or after. The purge continues and then shortly afterward, the unit shuts down and the module flashes 3 times. I'd have to look at the schematic again but as I recall that indicates an open circuit somewhere. Anything else that I can check with a multimeter that you can recommend before calling out a tech?
