How to do Mr coffee coffeemaker when lights come on by doesn't brew

If it is no longer brewing, the heating element or pump might be burned out with age.

Hi Floyd maybe this instructible will help! https://www.instructables.com/id/Repair-Your-Clogged-Coffee-Maker/

Put your coffee maker through one cycle with a mix of 1 cup of vinegar and water. Repeat with a cycle of just water.

Here is a site with troubleshooting steps:

If none of these steps helps, it may be time to upgrade. These appliances were not intended to be serviceable. There are several choices of coffee makers available at Walmart for under $20.

Here are 3 different possibilities.

Adequate Water Supply. Your Mr. Coffee Maker will not work without water. Open the top lid of the coffee maker and check that there is enough water to brew yourcoffee. Additionally, there is a water-level gauge on the front side of the pot that displays the water in the machine.

On my 4 cup Mr. Coffee, one of two thermal cutoff fuses is open. If either/both of those fuses is open, no power will reach the heating element and the water won't boil nor will the warming plate feel hot even if the power switch is lit.

They can be checked with an ohmmeter/continuity tester.

The thermal elements are accessible by removing the plastic cover on the bottom.

Probably the thermo cut-off device is stuck in "open" condition a safety component used to prevent over heating and potential fire. It's in the internal wiring to monitor the temperature where the water is brought up to boiling. It triggers every time as you finish brewing, to cut the flow of electricity to the heating coil. It now must be replaced which an experienced do-it-yourselfer can do, but you must find the right temperature "thermo-disc" (usually rated to open at about 220F/105C) to wire in. Unfortunately I've never seen one with a simple plugin feature. This is NOT an uncommon problem as a coffeemaker ages.
