My condensate line on my refer was brittle and fell apart. I removed the refer and replaced the tubing. It should have been an easy task, unplug from 120VAC, disconnect 12VDC wires, remove LP line, remove screws and pull refer out. Install new tubing and reverse process--but now the refer won't work (at least on gas, don't know about 120VAC). When turned on to gas I hear a hum from the control board and the check light comes on. Both fuses on the control board are good. I have only 2.94v on the J2 pin (this is the wire that carries voltage to my interior light and heat strip around freezer door). I have 13VDC at J4 which is what powers the board. I have no spark at the igniter. With this very limited info I hope someone can help.
