Roughly when did MM get their 150E units into use?

    McDonnell Miller 150E

    I installed a MM 150E on a WM LGB-6. The green power-on light on the control box does not light up. I definitely have wired correctly from the boiler's (L)1 and (L)2 terminals to the control box's H (hot) and N (ground) terminals. My only thought is that I must have a defective control box. Any alternative ideas?

    might want to put water in the boiler?

    I would doubt you have a defective control box, but anything`s possible. The green light on its exterior indicates power is present, are you sure you didn`t forget to turn a switch on? Use a meter and re-check your wiring and ALSO be sure to TEST for correct operation if your wiring does turn out to be mixed-up.

    Make sure to check that hot is on L1 and neutral on L2. Make sure you have a good ground also. Good luck.

    check your date code and talk w/your mm distributor, early in production they had problems with the lights that was corrected.
