I am new to the board. Lots of great information sharing going on.
I have a Mastertemp 400 NA Standard. Install 2014
I am getting the same conditions as Farmoci. The blower comes on, I can hear the gas valve open (smell gas) and it does not fire. It does this 3x and shuts down. My igniter shows 53 ohms so I know that is good. I know my AFS is good. I have good water flow. Fenwal blinks 3x for Ignition lockout. My grounds have no corrosion. I have jumpered out the AGS, HLS but same results. I also pulled the bottom bolt on the manifold to see if there was any water in the can. Nice & dry.
Can I pull the Igniter out of the chamber to see if it is heating? with the gas turned off. If I pull the connector off the igniter can I test the voltage there? I have a 240V system. It was running about a month ago.
How do you test S1 & S2? do I need alligator clips? I have a True RMS multimeter with the straight pins.
Any help would be appreciated.
