    True Electronic temp control board.

    I don't really work on refrigeration units but work said so. So we have a gdm-49f that will not go into defrost. I can manually do it but I have no voltage going to the defrost heaters. And yes I waited for time dely. Heaters draw 7 amps when jumped to line.

    Anything else I can check before ordering a $ board.

    No voltage but 7 amps, how’s that possible?

    No voltage going to heaters, but, 7 amps when he jumped out the control.
    Bad control board, some of those have controllers and a separate relay board, still, True charges a fortune for their junk.

    Have you confirmed the coil sensor is not reading warmer than the defrost termination temperature?

    Wouldn't a manual defrost override this? I did not check.

    No
    If the dot is on the heater relay should be on

    They probably didn't use a relay. so the board is handling full loads, hence the burnt board.
