Can a Coffee Maker Start a Fire? The Definitive Answer
Yes, coffee makers can start fires, although it is a relatively rare occurrence. The risk stems primarily from electrical malfunctions within the appliance.
While the odds of your coffee maker causing a fire are low, it’s a possibility that shouldn’t be completely dismissed. These appliances combine electricity, high heat, and plastic components—a trio that demands respect and proper handling. The core of the coffee machine fire risk lies in its internal heating elements and electrical wiring, which can fail over time or due to manufacturing flaws. But how can a simple kitchen appliance pose such a serious risk, even if it’s a rare one?
How Common Are Coffee Maker Fires? A Look at the Statistics for 2025
Coffee maker fires are rare, with estimates ranging from 30 to 60 incidents reported nationwide each year. However, the resulting kitchen fires contribute to an estimated $1 billion in property damage annually in the US.
To put the risk in perspective, it’s important to look at the numbers. While the idea of a coffee maker fire is alarming, the data shows it is not a common event. Here’s the bottom line:
- Consumer Reports: Data suggests that approximately 22 consumers report smoke or fire from their coffee makers each year. Other analyses, covering a five-year span, found an average of 60 reported coffee maker-related fires annually.
- Broader Electrical Risk: According to the U.S. Fire Administration, electrical malfunctions were responsible for 7% of all residential building fires in 2019. While this figure includes all electrical appliances, it underscores that any device you plug into the wall has a baseline level of risk.
The real danger isn’t just the frequency, but the potential severity. A small appliance fire can quickly spread to cabinets and walls, causing extensive damage.
According to the NFPA, kitchen fires are a major source of property loss, causing an estimated $1 billion in damages across the United States every single year.
Look at the proof. One specific incident involving a single defective coffee maker was reported to have caused over $100,000 in smoke damage to a home. So, while the chances are low, the consequences of a coffee maker fire can be devastatingly high.
The 4 Main Reasons Your Coffee Maker Can Catch Fire
Most coffee maker fires are caused by electrical issues like faulty wiring or a malfunctioning thermostat, design defects, or leaving the appliance unattended.
Understanding why a coffee maker can start a fire is the first step toward prevention. The risk isn’t random; it’s almost always tied to one of four specific failure points—some mechanical, and one entirely related to user behavior.
Pro Tip: Think of the thermostat as the appliance’s brain. If it malfunctions, the heating element doesn’t get the signal to stop, leading to dangerous overheating. Let’s break down each of these primary causes.
1. Electrical Component Failure & Faulty Wiring
Damaged, degraded, or improperly installed internal wiring can lead to electrical shorts and overheating, which can ignite the plastic components of the coffee maker.
At the heart of every electric coffee maker is a network of wires and electrical components responsible for powering the heating element. Over time, or due to manufacturing errors, these components can become a significant fire hazard. The main issues include:
- Wire Degradation: Constant heating and cooling can cause the protective insulation around internal wires to become brittle and crack, exposing the live wire.
- Damaged Wires: If the appliance is dropped or jostled, internal connections can loosen or break.
- Improper Installation: In poorly manufactured units, wires may be routed too close to the heating element, causing them to melt over time.
When these wires fail, they can create an electrical arc or “short circuit.” This generates intense heat in a very small area, which is often enough to melt and ignite the coffee maker’s plastic housing, starting a fire. Demonstrating the importance of these components, there is a specific safety standard, UL 1082, for household coffee makers that sets requirements for their electrical construction to minimize these risks.
2. Malfunctioning Thermostats and Overheating
A faulty thermostat can fail to turn off the heating element, causing it to run continuously, overheat, and potentially ignite the coffee maker itself or nearby materials.
The thermostat is one of the most critical safety components in a coffee maker. Its job is to monitor the temperature and switch the heating element off once the water is hot enough for brewing or once the “keep warm” cycle is complete.
When a thermostat fails, it can get stuck in the “on” position. This leads to continuous heating, where the warming plate or internal boiler never shuts off. The temperature continues to climb far beyond its designed limits. This unchecked overheating can easily cause the plastic base to melt, burn, and start a fire. This specific failure mode—the inability to shut off and subsequent overheating—has been the direct cause of several major product recalls involving hundreds of thousands of coffee makers.
3. Design and Manufacturing Defects (Recalls)
Major recalls, such as those for certain General Electric and Black & Decker models, have been issued because of design flaws that caused the coffee makers to overheat, melt, and start fires.
Sometimes, the danger is built right into the product from the start. Design and manufacturing defects are a serious cause of coffee maker fires, as evidenced by numerous recalls issued by the U.S. Consumer Product Safety Commission (CPSC). These aren’t just minor issues; they are fundamental flaws that create a direct fire hazard.
A stark example is the recall of approximately 900,000 General Electric-brand 12-cup coffee makers sold at Walmart. The CPSC initiated the recall after receiving numerous reports of the coffee makers overheating, resulting in smoking, melting, burning, and fires that caused damage to countertops, cabinets, and walls.
In another case, Applica Consumer Products recalled about 420,000 Black & Decker Thermal Coffeemakers because they might not turn off as programmed, leading to overheating and melting. These large-scale recalls prove that even reputable brands can produce models with dangerous defects.
4. Unattended Use
Leaving a coffee maker on and unattended significantly increases fire risk, with unattended use being a factor in 31% of all cooking fires.
The final major cause isn’t a mechanical failure, but a human one. Even a perfectly functioning coffee maker becomes a risk if it’s left on and no one is around to notice if something goes wrong. If a thermostat fails or a wire shorts out while you’re at work or asleep, a small problem can escalate into a full-blown fire without intervention.
According to the NFPA, unattended use contributes to 31% of cooking fires. While a coffee maker isn’t a stove, it’s still a heat-producing appliance that falls under this umbrella of risk. Leaving it on all day puts unnecessary stress and wear on its components, accelerating their deterioration and increasing the long-term chance of a malfunction.
A 4-Step Safety Checklist to Prevent Coffee Maker Fires
To prevent coffee maker fires, always unplug the machine when not in use, monitor it during operation, perform regular maintenance, and check the CPSC database for product recalls.
Now for the good news: preventing a coffee maker fire is incredibly simple. By adopting a few basic habits, you can virtually eliminate the risk and ensure your kitchen remains safe. This definitive safety checklist is based on recommendations from fire safety experts at organizations like the CPSC and NFPA.
Which of these simple steps can you start implementing today to make your kitchen safer?
- Unplug your machine when not in use. This is the single most effective way to prevent a fire. If the appliance has no power, it cannot malfunction, overheat, or short circuit. While many models have clocks or programmable features, the safest practice is to unplug it completely once you’ve finished your coffee.
- Monitor the appliance during use. Never turn on the coffee maker and leave the house or go to sleep. Staying nearby while it brews and keeps the coffee warm ensures you can react immediately if you smell burning plastic or see smoke.
- Perform regular maintenance and inspection. Periodically check the power cord for any signs of fraying or cracking. Make sure the unit is clean and free of debris. If your coffee maker starts behaving strangely—making odd noises, giving off a chemical smell, or not shutting off properly—unplug it immediately and discontinue use.
- Check for product recalls. Before you buy a new coffee maker, and periodically for the one you own, check for safety recalls. The U.S. Consumer Product Safety Commission (CPSC) maintains a searchable database on its website. This takes just a few seconds and can alert you to a known fire hazard.
To take your kitchen safety to the next level, consider investing in a smart plug with an automatic timer, which can ensure your coffee maker is never left on by accident.

FAQs About Coffee Maker Fire Safety
Here are answers to some of the most frequently asked questions about coffee maker fires and safety.
Is it safe to leave a coffee maker plugged in when not in use?
While many modern coffee makers have safety features, the safest practice is to unplug the machine when not in use, especially for older models, to eliminate any risk of electrical malfunction. Even when the machine is “off,” it may still draw a small amount of power, and a power surge or internal component failure could theoretically still pose a risk. Unplugging it is the only way to be 100% certain it’s safe.
Can you leave a coffee maker on all night?
No, you should not leave a coffee maker on all night. This constitutes unattended use, which dramatically increases the risk of fire if a malfunction occurs and also causes unnecessary wear on the appliance. Leaving the heating element on for extended periods accelerates the aging of the thermostat and wiring, making a future failure more likely. Always turn it off and unplug it before going to bed.
Do all coffee makers turn off automatically?
Most modern coffee makers have an auto-shutoff feature, but not all do, especially older or cheaper models. Importantly, this feature can malfunction and should not be relied upon as the only safety measure. As proven by the recall of Applica Consumer Products’ Black & Decker models specifically for “failure to shut off,” this safety mechanism can and does fail. Always treat it as a backup, not a primary safety guarantee.
Can a Keurig or other single-serve coffee maker catch fire?
Yes, single-serve coffee makers like Keurig can also catch fire. Any electric coffee maker has a potential fire risk, and there have been reported incidents and recalls involving single-serve models. For example, a lawsuit alleged a defective Keurig machine caused over $100,000 in smoke damage to a home. Additionally, ALDI recalled its Ambiano single-serve coffee makers due to a reported burn hazard, showing the risk is not limited to traditional drip machines.
