    Some boards look for micro-amps, some tenths of micro-amps. Always DC.
    Remember, Air Conditioning begins with AIR.

    Thanks that would explain it. Maybe my meter wasnt sensitive enough to read the Micro amps on this particular unit although i know i did read .1 uA on a unit befor i cleaned it. If it was much less than that i doubt my meter would pick it up. Giving the size of this flame rod it would make since it feeds back less uA . Thanks again good to know

    Bingo, I taught our guys to take proper reads FIRST and then if in doubt use jumper and screwdriver and also take read from that.

    I must say, I ALWAYS clean flame sensors with sand cloth. I have never had issues with said flame sensors ... ever due to sand cloth cleaning...


    Stay safe out there bros.
    I may not be the sharpest knife in the drawer, but compared to some I'm a razor...

    Cleaning out one of the vans! Can't believe all the stuff that was found.
    Ended up cleaning then testing the ones that looked ok on the shop furnace.
