Today the Heater stopped working with an AGS code.
Gas pressure is OK, verified.
I measured 59 ohms on the ignitor when disconnected from the system
I measured 240 volts to the board between the controller and the ignitor
I measured 43 volts to the ignitor when the system is on.
I measured 59 volts to the ignitor when the system is trying to ignite.
Ignitor does not glow.
Gas valve is operating normally.
