The comforting rumble of your garbage disposal – a familiar symphony in the kitchen. But what happens when that harmonious hum takes a menacing turn? A garbage disposal humming but not working can leave you with a sink full of frustration (and food scraps). Fear not! This guide will equip you to diagnose the issue and get your disposal back in top fighting shape.
Why is your garbage disposal humming but not working?
Several issues can cause a garbage disposal to hum without actually processing waste. Here are the most frequent culprits:
- Jammed blades: This is a common problem. Food scraps or utensils can become lodged between the blades, hindering their rotation.
- Tripped breaker or GFCI outlet: Your garbage disposal needs juice to work, just like any other appliance. If the breaker flipped or the GFCI outlet shut down, that could be cutting off the power.
- Overheated disposal: Overloading the shredder with too much waste at once or dumping incorrect items into it can lead to overheating which will then trip the safety shutdown.
- Faulty disposal unit: In other cases, the garbage disposals may just run their course and fail.
How can you troubleshoot a humming garbage disposal?
Hold off on repairs for a moment. Here’s a quick checklist to diagnose the issue:
- Turn off the disposal: Safety first! Always switch off the power at the wall or by using the dedicated disposal button before attempting any troubleshooting.
- Listen closely: Is the humming constant, or does it pulsate? A pulsating hum could indicate a jammed disposal.
- Check the reset button: Many disposals have a reset button located on the underside. Try pressing it to see if it kicks the disposal back to life.
What steps should you take to fix a humming garbage disposal?
Having pinpointed the likely cause, here’s how to address the issue:
- Jammed blades: There are two ways to clear a jam. First, try the Allen wrench trick. Most disposals have a hex socket located on the underside. Insert the appropriate Allen wrench and gently turn it back and forth to free the blades. Warning: Never stick your fingers down the disposal! If the wrench doesn’t work, you can use a long-handled utensil like tongs to carefully remove the obstruction.
- Tripped circuit breaker or GFCI outlet: Look in the house’s circuit breaker box. Another thing to do is to turn off the disposal switch from the “on” to the “off” position. If the GFCI detector is in the “off” then just switch it on. If you’re handling a tripped GFCI outlet then press the reset button directly.
- Overheated Disposal: Give the disposal a breather for 15-20 minutes to cool down completely. Once it’s good to go, try running it again with only cold water flowing. This will help determine if it restarts properly.
Why might your garbage disposal overheat or become jammed?
Here are some common reasons why your disposal might overheat or jam:
- Putting in the wrong things: This is a big one! Avoid grinding bones, fruit pits, coffee grounds, or excessive grease. These items can clog the blades or cause the motor to strain.
- Grinding up too much at once: Take it slow and steady. Feed the disposal scraps in small batches with plenty of cold water running.
- Dull blades: Over time, the disposal blades can become blunt. This can make them less effective at grinding and more susceptible to jamming.
What should you do if your garbage disposal is still humming but not working?
Exhausted from all the troubleshooting tips, and your garbage disposal persists with its humming serenade? This might be the point to bring in a qualified plumber. They possess the expertise to diagnose the exact problem and propose the best course of action, be it a repair or a complete disposal replacement.
How can you prevent your garbage disposal from humming in the future?
The old saying holds true: prevention is key! Here are some easy steps to keep your garbage disposal functioning smoothly and happily:
- Don’t put anything weird down the disposal: Just feed it leftover food scraps, not stuff that’s hard, oily, or like celery.
- Grind in small batches: Don’t overload the disposal. Feed it scraps gradually with plenty of cold water running.
- Cold water chaser: After grinding, run cold water for a few seconds. This helps flush away any leftover food particles and keeps the blades cool.
- Ice cube sharpening trick: Toss in a handful of ice cubes occasionally. The ice helps sharpen the blades and remove any built-up grease.
- Regular baking soda and vinegar clean: To make the task easy and for a quick clean, you can add ½ cup of baking soda and 1 cup of vinegar to the mix. You should foam it for a couple of minutes after pouring it into cold water.
When should you consider replacing your garbage disposal?
Even with the best care, garbage disposals eventually kick the bucket. Here are some clues that yours might need to be replaced:
- Constant humming or grinding noises: This could indicate worn-out blades or motor problems.
- Persistent leaks: A leaky disposal can damage your cabinets and cause water damage.
- Frequent clogs: If your disposal keeps jamming, you might want to replace it with a new one.
- Age: A normal garbage disposal should last almost up to 10-12 years. If you have an old console or issues with a system that is older than that, consider upgrading.
How can you safely maintain your garbage disposal?
An ounce of prevention is worth a pound of cure! Here’s how to keep your garbage disposal happy.
- Sharpen the blades regularly As discussed earlier, ice cubes can help maintain sharp blades. Alternatively, consider purchasing a disposal-safe grinder specifically designed for this purpose.
- Deodorise frequently: For long-term freshness, sprinkle baking soda and apply vinegar from time to time.
- Skip the harsh chemicals: Drain cleaners and other aggressive chemicals can damage your disposal. Stick to natural cleaning methods.
What are some tips to avoid garbage disposal issues in the future?
Avoiding future garbage disposal headaches is easy! Here are a few simple practices to keep your disposal functioning optimally:
- Invest in a disposal scraper: This nifty tool helps snag food scraps before they reach the blades, preventing jams.
- Keep it cool with cold water: Run cold water before, during, and after using the disposal. This flushes away scraps and keeps the blades from overheating.
- Not everything goes down the drain: Coffee grounds, eggshells, grease, and stringy vegetables like celery should be composted or trashed. Such items can jam the blades or make the motor work harder.
