Coffee maker turns off mid-brew or randomly shuts down before the cycle is complete.

Safety first: Unplug the unit before opening the base or control housing.

• Check ventilation and placement: Ensure the coffee maker is not pushed tightly against a wall or under low cabinets where heat can build up. Provide at least a few inches of clearance.
• Test on a different outlet: Plug the unit into a different circuit to rule out voltage drops or loose wall outlets.
• Inspect internal connections (advanced): Remove the base and gently tug on push-on connectors to the heater, thermostat, and control board. Reseat any loose connectors.
• Observe pattern: If shutdown always occurs at the same point in the brew, the thermal cutoff or thermostat may be opening prematurely and should be tested and replaced if faulty.

Persistent mid-cycle shutdowns after these checks typically require replacement of the thermal cutoff, thermostat, or control board.
