How To Replace or Fix Garbage Disposal Blades?

Ah, the mysterious world of garbage disposal blades – or should we say, impellers? Let’s slice through the misconceptions and get to the meaty truth of these kitchen marvels.

Contrary to popular belief, your garbage disposal doesn’t house a set of razor-sharp blades waiting to pulverize your food scraps into oblivion. Instead, it’s home to a sophisticated system of blunt impellers and a grinding ring that works in harmony to break down your culinary cast-offs.

These impellers, often mistaken for blades, are the heroes of your kitchen sink. They spin at high speeds, flinging food particles against the grinding ring, which does the actual work of breaking down the waste. It’s less “slice and dice” and more “spin and smash” – a ballet of centrifugal force and clever engineering.

Your fridge is a kitchen superstar as it keeps all your food fresh and drinks cold.



But does the fridge feel warm when you open it?
Is there water all over the floor?
Fridge issues are the worst!

Diagnosing Blade Issues

Before we get elbow-deep into repairs, let’s sharpen our detective skills to pinpoint the problem. Is your disposal humming like a contented cat but not actually grinding? Or perhaps it’s making alarming noises that sound like a small robot having an existential crisis?

Here’s your step-by-step guide to becoming a garbage disposal detective:

  1. Safety first! Turn off the power at the circuit breaker. We’re going for kitchen efficiency, not kitchen electrocution.
  2. Grab a flashlight and peer into the disposal chamber. Look for any obvious obstructions or damage. You might spot a rogue bottle cap or an ambitious avocado pit.
  3. If the disposal hums but doesn’t grind, you might have jammed impellers or dull blades.

Remember, diagnosis is half the battle. Once you’ve identified the culprit, you’re ready to move on to the fix.

Unjamming Stubborn Blades

So, you’ve discovered your impellers are jammed tighter than your great-aunt’s Tupperware lid. Fear not! Here’s how to free them:

  1. Locate the hex-shaped hole at the bottom of the disposal.
  2. Insert an Allen wrench into this hole. This is your magic wand for this kitchen spell.
  3. Turn the wrench back and forth, as if you’re steering a very tiny ship through choppy waters.
  4. Once you feel the resistance give way, you’ve successfully unjammed the impellers!

Now, restore power and test your handiwork. If your disposal springs back to life, congratulations!

Sharpening Dull Impellers

“But wait,” you might be thinking, “how can I sharpen something that’s intentionally blunt?” Well, dear reader, prepare to have your mind blown by the ice cube trick:

  1. Grab a tray of ice cubes. The more, the merrier!
  2. Dump them into your disposal like you’re hosting the world’s tiniest ice bucket challenge.
  3. Turn on the cold water, then the disposal, and let the party begin.

The ice helps clean the impellers and, in a way, “sharpens” them by knocking off any built-up gunk.

Replacing Grinding Components

If your disposal is still being stubborn, it might be time for some more serious intervention. Here’s how to replace the grinding components:

  1. Disconnect the disposal from power and plumbing. 
  2. Remove the unit from under the sink. It’s heavier than it looks!
  3. Channel your inner watchmaker and disassemble the unit to access the grinding chamber.
  4. Replace the impeller plate and grinding ring. Out with the old, in with the new!
  5. Reassemble everything!

Maintenance Tips for Longevity

Prevention is better than cure, especially when it comes to garbage disposal. Here are some tips to keep your disposal running smoothly:

  1. Avoid grinding fibrous materials. Your disposal is not a juicer – keep those celery strings out!
  2. Always run cold water before, during, and after using the disposal.
  3. Regularly clean with ice cubes and a baking soda/vinegar mixture.

Remember, a well-maintained garbage disposal is a happy garbage disposal. And a happy garbage disposal means a more efficient, odor-free kitchen for you!

FAQs

Technically, garbage disposals don’t have blades. They use blunt impellers that don’t need sharpening. However, you can improve their efficiency by grinding ice cubes, which helps clean and de-gunk the impellers.

Impellers don’t typically need replacement unless damaged. With proper maintenance, a garbage disposal can last 8-15 years. If you notice persistent grinding issues, consult a professional like CLT Appliance Repair for an assessment.

Absolutely not! Never reach into a garbage disposal, even if it’s turned off. Always use tongs or pliers to remove objects, and disconnect the power before any maintenance.

A humming disposal usually indicates jammed impellers. Try using an Allen wrench in the bottom hex hole to manually turn and unjam the impellers. If this doesn’t work, call a professional.

It’s best to use cold water. Hot water can melt fats, causing them to re-solidify further down the drain pipe, potentially causing clogs. Cold water keeps fats solid so they can be ground up and flushed away.
