I have a Teledyne Laars Series 2 ESC heater. My pilot light will not light. Took everything apart cleaned it out and still nothing. Then replaced ignition control box - still nothing. I am getting a spark, the transformer is giving 28 V, the PV line is giving 28V, checked fusible link, pressure switch, etc. Everything seems okay. Starting to think it is the gas valve - I never smell gas.
There are three wires going into the gas valve - does anyone know what the voltage should be on the MV line? I don't have any voltage coming off that one??
Any and all help would be appreciated!
