The brewing light is on but, no sounds or other signs of brewing. Power is good. Need to also know how to check for particle accumulation.

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. I will bypass the failed fuse by wiring a new 216C/250v/10A device in parallel. All connections are crimped or spot welded so the new fuse leads will have to be wrapped around the existing leads.

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.

Mine was coffee maker bout 6 mths old but mr coffee replaced it with brand new unit if now we can figure how to program everything on it thanks Mr Coffee

Try this from the troubleshooting guide.

I need to replace the rocker switch the light burned out. The center terminal pin came right out. I didn’t realize that there was a safety feature in that switch. Is it available? Paul

mr coffee light is on but stopped brewing what do i do heating element still warms coffee

Mine stopped brewing but the light was on also. So I checked the plate and it was not warm. I did what I thought I should do to clean it. Still nothing. But it only cost 10 dollars. Is it worth trying to fix it and would it be safe. I decided not to get another Mr Coffee because I only had it since beginning of January. After reading these messages. It must be a flaw in most of these 5 cup coffee machines.
