Michael L for Model Number SBD21VPE The supply valve to my refrigerator recently starting leaking through a weld in the plastic housing. I replaced it with part number WP12544001. After that the ice maker was not getting adequate water and the fil tube kept freezing up. I defrosted it and replaced the secondary valve, part number 12544101. The problem still persisted and I noticed that while the ice maker was getting 117VAC (tested between test points L & N on the icemaker control model), the ice maker side of each valve (brown coil) is only seeing 99 to 101VAC. I verified this at the connector to each valve and on the ice maker control module test points N & V. During the entire harvest/fill cycle, I see 117VAC between L & N. I replaced the ice maker with part number D7824706Q and I see the exact same behavior. Where do I go next? I have a hard time believing it's the thermal fuse in the harness as the icemaker motor seems to function properly and the heater is heating. I also verified that I get much better flow from the icemaker side of each valve when I connect the harness for the water dispenser, where I verified 119VAC is seen.
Answer Michael, On the wiring diagram it appears they power the secondary valve at some point with a splice off of the primary valve.This has to be where you are losing some voltage possibly a damaged wire or connector.There is nothing else in between the power leaving the ice maker.The splice will be in the machine compartment where the compressor is.
