If your Black+Decker 12-cup coffee maker is completely dead—no lights, no sound, no heat—the issue is almost always a break in the power connection. Before you consider a repair, work through these specific, ordered checks.
Quick Answer: Unplug the coffee maker, wait 10 seconds, and plug it firmly into a different, known-working outlet. Ensure the front power switch is clicked to the On position.
Why Your Black+Decker Coffee Maker Won’t Power Up
A total lack of response means the appliance isn’t receiving the 120V AC it needs. The failure point is typically in one of three areas: the outlet and home circuit, the coffee maker’s external connections, or its internal components. We start with the simplest, most common fixes.
Check the Power Connection
First, locate the rocker switch on the front panel and ensure it’s firmly in the “On” (—) position. Next, trace the 3-foot power cord from the back of the unit to the wall. Unplug it, then plug it back in firmly, ensuring the prongs make full contact. A plug can become partially dislodged in a crowded power strip, creating an intermittent connection that delivers no power.
Verify the Outlet is Working
Eliminate the outlet as the source. Unplug the coffee maker and test the same outlet with a device you know works, like a lamp or phone charger. If that device also fails, the outlet is dead. Immediately test your coffee maker in a different, functional outlet in another room. This instantly tells you if the problem is with your kitchen’s wiring or the appliance itself.
What to Do If It Still Won’t Turn On
If the unit is connected to a confirmed live outlet and the switch is on, but it remains dead, the cause is more serious. Do not disassemble the unit, as this is hazardous and voids the warranty.
Check for a Tripped Circuit
Kitchen outlets are often on protected circuits. First, inspect all countertop outlets for a tripped GFCI (with “Test” and “Reset” buttons) and press “Reset.” Then, check your home’s main electrical panel for a tripped breaker (one that’s flipped to the middle or OFF position) on the kitchen circuit and reset it.
Contact Customer Support
After ruling out external power issues, the fault is internal—likely a failed power switch, wiring harness, or main control board. Contact Black+Decker consumer service at 1-800-465-6070. Have your model number (like DCM12B or similar, found on the bottom plate) ready. They can confirm warranty status, advise on a possible part replacement, or initiate a claim for a model-specific issue.
Frequently Asked Questions
Is there a fuse inside my Black+Decker coffee maker?
Yes, a thermal fuse protects the heating element. It is not user-serviceable. A blown thermal fuse is a common failure point after a power surge and requires professional repair.
Can a dirty coffee maker cause it not to turn on?
No. Mineral scale buildup affects water flow and heating efficiency, leading to slow brewing, but it cannot interrupt the primary electrical connection needed for the unit to light up.
My coffee maker was working and now it’s not after a power outage. What gives?
A power surge likely damaged the internal circuitry or thermal fuse. Even if the outlet works, the appliance’s sensitive components may be fried. Testing in another outlet confirms the damage is to the coffee maker itself.
The “On” light is on, but it’s not heating or brewing. Is this the same problem?
No. An illuminated light confirms power is reaching the unit. The failure is downstream, typically with the 1000-watt heating element, thermostat, or pump. See our guide on brewing issues for next steps.
How long is the warranty, and what does it cover for a no-power issue?
Most Black+Decker coffee makers have a standard 2-year limited warranty from the date of purchase. A no-power defect caused by a manufacturing flaw (like a bad switch or wiring) is typically covered, excluding damage from misuse or power surges.
I hear a faint hum when I turn it on, but nothing else happens. What does that mean?
A hum means power is reaching an internal component, like the heating element or pump, but it’s failing to activate properly. This could indicate a seized pump, a shorted heating element, or a failing control board. Unplug the unit and contact customer service, as continued use could be unsafe.
