Why Is My LG Ice Maker Making Knocking Noise?
Jammed or iced-up ice maker
We’ve all been there – you’re chilling at home when suddenly your LG fridge starts making a racket. What’s the deal? More often than not, it’s that darn ice maker acting up. When ice or junk gets stuck in there, it can’t do its job right and starts knocking around like crazy.
We’re gonna need these tools to get that stuck ice bucket out:
Hair dryer – Don’t use it! It’ll mess up the plastic parts.
Garment steamer – This is what you want. It’s great for melting ice without warping stuff. We can focus the hot steam right where we need it.
Bucket lid wrench – Might come in handy for getting the lid off.
Ice shovel or scraper – These help us dig out all that ice buildup.
General take-apart tool – We might need to take things apart to get at whatever blocking it.
Impeller remover – This is special for getting rid of clogs in ice buckets and stuff.
Worn-out ice maker gears
The second biggest reason for LG fridge ice makers making that knocking noise? It’s the worn-out gears inside. After a while, those little gears in the ejector thingy get all busted up, and that’s when you start hearing those loud knocks and thumps.
Wanna fix it? Here’s what we gotta do:
We need to get our hands on that ice maker. It’s inside the fridge, and we’ll probably need to unscrew some stuff to get it out. Once we get it, let’s take a good look at the gears. If they look all messed up or cracked, we’re gonna have to swap them out.
Next step is getting new gears. We can order them from LG or find some that’ll work with our fridge model from other places. Once we got the new parts, we gotta take apart the ice maker really carefully like. Then we’ll put in the new gears where the old ones were.
After that, we just put everything back together and stick it back in the fridge. If we did it right, that annoying knockin’ should be gone!
Frost buildup around the ice maker
Here’s what we’re gonna do:
- First things first, unplug that fridge and take out the ice maker.
- Now, let’s clean off all that frosty stuff. Use a soft cloth or brush – don’t go stabbing at it with anything sharp or you’ll mess up the parts!
- Check if your fridge is level. If it ain’t, adjust those little legs at the bottom. It should be level both ways – front-to-back and side-to-side.
- Set your freezer temp between 0°F and 5°F (that’s like -18°C to -15°C for you metric folks). If it’s warmer than that, you’ll get more frost.
- Put everything back together and plug it in. Give it a day to chill out (pun intended) before you start making ice again.
If you’re still getting frost building up real quick, or if that knocking won’t quit, you might need to call in the pros. LG support can help you out if the defrost system’s acting up.
Water supply issues
if your ice maker’s making this weird knocking sound, it might be a water supply thing.
Like, if you’ve got it turned on but there’s no water hooked up, it’ll keep trying to do its thing and make these super annoying buzzing or clicking noises.
We’ve been there, and it’s not fun. But don’t worry, we got a simple fix for ya! Just turn that ice maker off until you can get it hooked up to some water. Trust us, it’ll shut right up once you do that.
no water = noisy ice maker. Turn it off = problem solved. Easy peasy, right? Let us know if you need any more help with your fridge troubles!
Compressor issues
We’ve had this problem before with our LG fridge ice maker – it’s making all kinds of racket! If your compressor’s goin’ faster than it should, you might hear knocking, buzzing, or banging noises.
It’s usually because of compressor issues, and we definitely needed a pro to fix it.
Here’s what we did to try and fix the compressor noises:
- We checked if the compressor was running too much or too fast. That can make it vibrate more and knock around.
- We made sure the fridge was sitting level and not rocking. If it ain’t level, it stresses out the compressor and makes weird noises.
- We got someone to check the refrigerant. If it’s low, the compressor has to work really hard and gets noisy.
- We had a repair guy look at the compressor windings and start parts. Sometimes you gotta replace the whole thing if it’s busted.
- We cleaned condenser coils too. If they’re all gunned up, the compressor has to work overtime.
- We made sure the voltage to the compressor was right. Low voltage can make it overheat and sound funny.
Loose or worn door hinges/stoppers
the ice maker kept making this annoying knocking sound. Turns out, it was cuz of loose door hinges and stoppers! The vibration when we opened and closed the door was messing with the ice maker.
Here’s what we did to fix it:
- We checked all the hinges and stoppers. Some were loose, so we tightened them up. A couple were pretty worn out, so we replaced those.
- We put a little bit of silicone lube on the hinges and stoppers. It helped smooth things out and cut down on the vibration.
- We made sure the fridge was level. If it’s not, the door can sag and make things worse.
- For the really bad hinges and stoppers, we just replaced them completely. That really did the trick!
Vibration from improper leveling
We gotta make sure our fridge is level, or it’ll start making these annoying knocking sounds. Here’s what we can do:
First, let’s check if it’s level. If you have a spirit level, great. If not, no worries – just put a glass of water on top and see if it looks even.
Next, we gotta mess with their levelling legs. There are two in front, by the wheels. Turn them clockwise to raise it up, or the other way to lower it. We want it straight side-to-side, but a tiny bit tilted back so the doors shut well.
While we’re at it, let’s make sure the doors line up right. If they don’t, the room’s moisture can get in and make frost.
Oh, and if it’s too cold inside, that can make frost too. Maybe turn up the temp a bit for a couple of days. That should get rid of the frost and quiet things down.
FAQs
How do I stop my ice maker from knocking?
Why does my refrigerator make a knocking noise when making ice?
The knocking noise during ice-making can be due to ice buildup interfering with the fan blades, a faulty ice maker motor, or issues with the water inlet valve affecting the water flow.
Why does my LG ice maker make a squealing sound?
A squealing sound from an LG ice maker is often due to a malfunctioning fan motor or fan bearings that need replacement. It can also be a sign of a motor struggling due to ice buildup or obstructions.
How do I fix my freezer knocking noise?
Fix a freezer knocking noise by ensuring the appliance is level, checking for and removing any ice buildup around the evaporator fan, inspecting the fan motor and blades for damage, and verifying that the water supply line is not kinked or obstructed.
Is it normal for ice maker to make noise?
It’s normal for an ice maker to make some noise during operation, like a humming or buzzing when filling with water, or a clunking sound when ice is being ejected into the bin. However, excessive or unusual noises like knocking or squealing are not normal and often indicate an issue that needs attention.
