LG ice maker over flowing

I have a LG fridge with a bottom drawer freezer with ice maker. It from time to time will over flow and i just get chunks and the bin freezes solid. Could this be the water valve?

Welcome to the forums.

It could be a leaking fill valve.

What's the model number of your fridge ?

Thanks for posting the model number.

It would appear that your problem is directly related to the fill valve. The valve is part #5220JB2010A. It may have something stuck in the seal.... possibly sand or grit if you're on a well system.

Be sure the water supply valve to the fridge is turned on all the way. Another issue can be a clogged saddle valve. These fill valves require better than 25 psi of water pressure to operate correctly. A clogged saddle valve could cause it to leak.

This is one site that carries the valve... Water Inlet Valve 5220JB2010A Repair Clinic

I have an LG 3-d00r fridge that had this intermittent ice maker leak. It didn't happen all the time but when it did, the cubes would often be only partially frozen, stuck together in the bin and, worst of all, the floor of the freezer was covered in a thick layer of ice. When the floor ice built up enuf, water would leak out onto the kitchen floor!

I replaced both the icemaker and the water valve and the problem persisted.....

I finally found the real problem. My ice maker was connected to a reverse osmosis system that only provided 15-20 psi of pressure.....not enough to reliably close the fridge's water valve! I bypassed the RO system and installed an inline charcoal filter (we have a sulfur taste in our water) and the pressure rose to my usual 40 psi (we're on a well system). Voila! The ice maker now works perfectly.

Welcome to the forums.

Thanks for the info on your fridge. Glad you figured it out.
Many people don't realize that those valves need proper water pressure to operate correctly.
