Coffee not brewing but light is on.
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.
Is this a good question?

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.

This was my problem and the solution did not work. Off to buy a new coffee maker.

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.

This is what is wrong with mine but it isn't intended to be soldered in. I havn't had mine long but after looking around on the internet, I suspect a weak compontent. I may just buy a new coffee maker rather than fool with it.
I like Rick’s addition to my answer. To clarify, the old thermodisc does NOT have to be removed, because it is OPEN. As he says, just fasten the new leads around the old one (in parallel).
Same problem here, but mine is brand new. I've only used it twice and it already broke. Am cri
mine IS brand new! Never used. Light comes on but bottom of disc doesn't heat or does it get the water hot or runs it through. HELP!!!
I’ve got 120 to the heating element and still do not have heat. It appears both resisters are good? Any ideas?

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.
