weil-mclain ignition problem
Checking the boiler WM HE for the season as usual. Called for heat, draft fan comes on, the hot surface igniter glows after prescribed delay gas valve clicks but does not open for main burner ignition. I tried several times, different mechanical sounds. Put a meter on valve wiring, when gas valve clicks I read voltage which immediately goes away. Gas valve or ignition control?
