    raypac 406 ignition lockout trouble

    Spa/pool heater
    Propane/ atmospheric unit

    when I turn on spa
    I get a CFH call for heat
    Pilot lights....... but SPK is still displayed
    min later I get ignition lockout burner never lights

    Ops manual page 45 has a trouble shoot
    I get to test mv-mv/pv I pull the purple and yellow wires and test for ac, I get a spike when spark goes off and zero in between sparks

    am testing wrong? ..............manual say replace module is this simply the pilot assembly with ignitor?
    How does this thing know the pilot is lit? ...............the only wire to the pilot is the blue ignitor wire (Honeywell pilot) I don't see any sensor

    As I type and read the manual I'll back up one and test the step prior also..........Check for 24 VAC across PV-MV/PV terminals on PC board. If voltage is okay,
    replace gas control; if not, replace PC board.
    NOTE: If PC board goes into lockout, reset system

    have reset system power supply off
    burner only had one small dirt dobber plug..cleaned it

    Thanks for the help headed out of town will check pool school forum and test again later in the week

    When I test PV to MV/PV on the back of the panel same results meter spikes to 18 VAC (when spark ignites) then to zero, I say 18 VAC really head to read never stabilizes

    I'll try the board, I thought that was where I was headed.
    Thanks Paul, as a volunteer fireman, I know all to well the dangers of gas/propane fired heaters. One must know his limitations.
