Thank you for using Just Answer, I will quickly, and methodicly work through your repair needs.......Thank you.........Michael, hi with no control lights inside, ck to see if the refer has 12volts to the control board, thanks your model uses two boards, upper and lower, the lower board is the control, changes from gas/elect, the upper is the igniton module, opens gas valve, and sends ignition signal to the burner

Ck'd for 12 volts at Lower control board 12 v on terms j3&j4
Expert:  Michael Reush replied 2 years ago.
thanks for getting back to me, take the cover off of the lower board, and you will see fuses on the board, unplug the electrical (120vac) and test the fuses, one is for 12 v the other is ac.

thanks, ***** ***** the coach, look at the refrigerator and see if you can find the high humidity switch, work that switch back and forth , and see if the refer comes on, if not, take the switch out, check for power there, then test the switch for its sending power out on one of the two outputs,
