Keurig Troubleshooting

Keurig is a popular brand of coffee makers that has been around for many years. One of the frequent problems Keurig users experience is when their Keurig Slim won’t turn on.

In this article, we will discuss some of the reasons why your Keurig Slim may not be turning on and how to fix it.

Why Keurig Slim Won’t Turn On?

There are several reasons why your Keurig may not be turning on. Check the following reasons and see whether one of them is causing you trouble.

Reason 1: Power Button Is Not Pushed

The first thing you should check is whether the power button is pushed to turn the brewer on.

Reason 2: Overheated Thermostat

There is an overheated thermostat inside the Keurig Slim that may need to be reset with a paperclip. Sometimes, the thermostat just pops because the tank runs dry, the added water light doesn’t work, or the tank will run dry during the descaling process. Your Keurig may also overheat from the descale process itself.

Reason 3: Faulty Power Cord And Power Outlet

If the power cord is damaged or faulty, your Keurig Slim may not turn on. Check the power cord for any visible damage or fraying. You may also want to check the power outlet for any damage.

Reason 4: Clogged Water Lines

If the water lines in your Keurig Slim are clogged, it may not turn on. This can happen if you don’t descale your Keurig regularly.
