My refrigerator just started making a noise like a jackhammer when I use the water dispenser. Do I need a new water inlet valve?

I have a Sears Kenmore Elite refrigerator, item number 106.56703500. My refrigerator
just started making a noise like a jackhammer when I use the water dispenser. Do I need a new water inlet valve? If so, is part number AP3085178 the right one?

Always hearing noise on an appliance can be annoying to always hear so when an appliance starts to have problems it can get concerning just to even think about what might be the problem. While you are waiting on an expert to answer your question, I took so time to research your question in Manage My Life website, I found this great link on Refrigerator making noise. I attached the link below. Hope this helps!

You are correct in diagnosing the water valve as the problem. The jackhammer noise is caused by a mechanical failure inside the water valve.

You can order the part and see a parts diagram for your refrigerator at [partsdirect.com?sid=MMLxexpertxmerch]. The water valve is located on the "icemaker" page and is part number 2305225. The cost is $95.13.

Jimmy K: Thanks for the confirmation. Bought the part and installed it, but when I try to dispense water, I hear the valve opening (I think), but there is no water flow.

So far, I've tried holding down the electronic reset button next to the "power outage" diode, with no effect.

Any advice you can share? Maybe I connected the hoses or the wiring harnesses out of sequence, if the sequence is important.

Thanks!

Dave, I don't think you could connect the wiring wrong, the connector won't go on the valve wrong unless you really push. I suppose you could have connected the water lines wrong, but I think that is unlikely.
Get someone to hold the dispenser cradle in while you inspect the water valve. I suspect you received a faulty water valve.
If you don't find something you did wrong, call Sears Parts Direct and get them to send you another water valve.

Jimmy: Thanks for the very prompt response. I did some experimenting in the meantime, and it turns out that my filter cartridge has been blocking the water flow. With the cartridge removed, the old inlet valve works fine and there is no rattling. So I'll be returning the valve I just bought and buying a new filter cartridge (it was almost time to replace it anyway).

Thanks for your insights on this problem.

Jimmy: One more thing I forgot to mention: With the filter in place, I got the rattling noise (eventually) no matter which inlet valve I used. And the rattling was from far underneath the fridge, not from the inlet valve. So I guess when water is blocked (anywhere), the pump makes that noise because it is working too hard -- and the the blockage can occur in other places besides the inlet valve. Is that correct? Thanks again.

Dave, if the filter is partially blocking the water flow, the erratic flow can cause the tubing to move and rattle against the parts in the refrigerator. Something like this might be happening in your refrigerator. It is very unusual for a blockage to occur inside the water tubing, but strange things happen sometimes.
The refrigerator does not have a pump to circulate the water. The water valve opens and lets the water pressure of the house plumbing push the water through the tubing to the icemaker or dispenser.
It does sound like replacing the water filter might solve the problem. You might try removing the water filter. With the filter removed the water should bypass the filter and flow at normal pressure.

New problem but probably related: in the icemaker, the IR transmitter PCB doesn't seem to be getting power anymore. Could I have accidentally disconnected something when replacing the inlet valve?

You should have 120 volts ac between the black and white wires on the transmitter board and the receiver board at all times. The wiring does not go through the water valve wiring. It would be possible to disconnect a wire inside the cabinet if you pulled on the icemaker wires too hard.
If you don't have the voltage to the 2 boards, remove the evaporator cover in the rear of the freezer and check the wires going down to the water valve.
