Keurig Won't Turn On: Power Supply, Thermal Cutoff, and Reset Fix
Quick Answer
Keurig won't power on at all: check the outlet (plug in a phone charger to verify). Check the power cord connection at the back of the Keurig (it can work loose). If outlet works and cord is seated: the internal thermal cutoff fuse has blown. This fuse blows when the heating element overheats (usually from scale buildup or running the machine dry).
Keurig won't power on at all: check the outlet (plug in a phone charger to verify). Check the power cord connection at the back of the Keurig (it can work loose). If outlet works and cord is seated: the internal thermal cutoff fuse has blown. This fuse blows when the heating element overheats (usually from scale buildup or running the machine dry). The fuse is inside the machine and is NOT designed to be user-replaceable - Keurig considers it end-of-life. However, DIY repair is possible: open the bottom panel, find the thermal fuse on the heating element wires, and replace with a matching automotive blade fuse. This is an advanced DIY fix that voids warranty.
