Cost GuideUpdated June 10, 2026
Garbage disposals put up with a lot in busy Palos Heights kitchens. Over time, it's common for these devices to jam from food buildup, bones, hardened grease, or non-food items that slip in by mistake. When your disposal won't run or hums without grinding, it's likely jammed. Some jams are easy fixes, but ignoring the problem or forcing the unit can lead to costly motor damage or even leaks under the sink. Resetting a jammed disposal is something homeowners can attempt on minor clogs, but knowing the right steps and limits matters for safety and cost control.
Why Jammed Disposals Happen in Local Homes
Most Palos Heights homes were built from the 1960s through the 1990s, and many original kitchens still have older or mid-grade disposals. Over decades, hard water from Lake Michigan can cause mineral buildup on the unit's moving parts. Local clay soils can also mean more frequent drain backups, especially if the kitchen drain connects to older cast iron or galvanized pipes. Grease, fibrous foods, and starchy scraps like potato peels are known catch points. Sometimes, the jam is from a foreign object, utensils and small bones are common culprits.
How to Safely Reset a Jammed Garbage Disposal
Our team sees homeowners attempt all kinds of DIY fixes. A reset may solve the problem if it's a simple overload trip, but a true jam often needs hands-on work. Here's a step-by-step guide for the average Palos Heights kitchen:
- Turn off the disposal and unplug it (or flip the circuit breaker).
- Check for visible obstructions inside the unit (never use your hand, use tongs or pliers).
- Use the hex key (most disposals have a slot on the bottom for this) to manually rotate the impeller and free the jam.
- Press the red reset button on the bottom of the disposal unit.
- Plug the disposal back in and run cold water. Test the unit in short bursts.
If you hear humming without grinding, or if the reset button won't stay engaged, the jam may be severe or the motor could be compromised. That's often the point when calling a professional makes sense to avoid further damage or electrical risk.
What Can Go Wrong with DIY Disposal Resets
Trying to force a stuck disposal or running it repeatedly after a jam risks burning out the motor. Older homes in the Chicago area, like those in Palos Heights, may have outdated electrical setups under the sink, sometimes still on a shared circuit or without a GFCI outlet. Water and power are a bad mix, so safety matters. If your disposal keeps tripping the breaker, emits a burning smell, or leaks from the housing, it's best to get help. Sometimes, a jammed disposal is a symptom of a larger drainage problem. Our drain cleaning service can clear deeper clogs if food waste is backing up.
Costs to Reset or Repair a Disposal in Palos Heights
Resetting a disposal yourself usually only costs a bit of time and patience. If you need a replacement hex key, those are inexpensive at any hardware store. Professional resets, minor repairs, or jam removals will be more, but typically far less than installing a new unit. Older disposals that hum but do not run may need internal parts replaced, and an electrician may be needed if wiring is damaged.
Our crew always checks for leaks from the sink flange and the discharge tube after a jam, since older setups with clay or cast iron drains can loosen over time, leading to water underneath the cabinet. If your disposal repeatedly jams or leaks, it may be time for complete garbage disposal service or even an upgrade.
When to Call a Plumber for Help
Some cases are better left to the pros. If you're dealing with water under the sink, persistent clogs after resetting the unit, or electrical issues, it's safer to bring in licensed help. Our plumbers also handle related issues, including pipe repairs for homes with older galvanized or cast iron supply lines, which are common in this area. Water backing up from the disposal into other drains may signal a main drain issue, which ties into our sewer line services.
For those updating their kitchens, our faucet and fixture installation team can make sure everything is code-compliant and set up for long-term use, including sump pump discharge lines, a useful feature given Palos Heights' clay soils and basement seepage risks.
Signs Your Disposal Needs Professional Attention
- The reset button pops out repeatedly or won't stay engaged
- The unit hums but does not grind, even after manual rotation
- You find water leaks under the sink after a jam
- Persistent drain backups even after clearing the disposal
- There is a burning smell or signs of electrical overheating
We see all these situations in Palos Heights kitchens, often in homes with original kitchen plumbing or with disposals past their expected lifespan. The cost to repair or reset before the motor fails is usually much less than waiting until the unit stops working completely.
