I Just replaced the transformer. Cleaned The burner and pilot assemblies. Checked electrical connections.Checked input power ,Getting 120V in ,Checked transformer output across both load connectors,getting 27V out,but not getting the voltages needed to reigniter and gas valve.not sure if the new transformer wiring needed to be wired differently .when checking the voltages from the new transformer load contacts seperatly I was getting 17V from one side and 1.9V from the other.
