Mr. Coffee Pot - 5 Beeps - Won't Brew - No Heat - Fix - SOLVED

You can find videos on how to take it apart. This video is how i found the problem. Produced it and solved it!

Thanks! You just helped me fixed my coffee maker.

I appreciate you taking the time to make the video. Same problem I am having but my goodness you made my brain hurt. I’ll just go buy a new coffee pot. Maybe with morning caffeine I can pretend to be an electrical engineer

I have the same problen with my Mr Cofee, but don't understand how did you fix it.

[@TheDukeWayne88]

Just had this same problem this morning. Thank you for taking the time to show the tear down and explaining the problem.

[@oppy2002]

My fuses, switches and thermostat all ohm out (bleep). My pot shows brewed when nothing has brewed (after I hit the brew button the pot immediately shows brewed when no coffee has been made) There all also 3 very faint beeps.. Thanks for the video. It is nice to see there are people who still want to fix things instead of throwing it out and buying another. Also, I sympathize with you in reference to not having any appliance parts stores in your area. There used to be several around here that now are out of business.

[@DrcJr77]

Agreed and thank you. If you are getting 3 beeps immediately, then you have a problem with most likely temp / high limit sensor shown in this video. Remember while testing ohms the difference between normally open vs normally closed. Which I'm assuming you already know, but it's worth mentioning to cover bases. I hope you get it fixed and thanks again for the kind words.

[@oldengguy]

Thanks...I'm pretty confident this is where my problem is. Now all I need to do is find the right kind of screwdriver to get those screws out.

[@pheehzero]

Thanks for going through this...mine was the 2 fuses, same condition. Thermal carafes are the same, they just isolate the heating unit and shield it. The 1st thermo-cycle shuts them down.

[@TheWyldnwillie]

Nice, I was thinking "thermistor", now I have to check that switch. It is scary when the coffee pot won't turn on!

[@DrcJr77]

thermistors are normally both temp sensor and or high limit sensor. In this case, if your symptoms are 5 beeps at startup. Then Yes, high limit switch is what you need to replace. Testing would consist of checking for ohms whiling heating.

[@madcrabber1113]

Still have a Mr. Coffee machine from the late 70's or early 80's (can't remember exactly since it was my parents) the thing still works great and gets much hotter than modern machines that I have now.

[@DIY_CEO]

I was curious why it always goes bad and had to check to see if there is a fix. thanks for this.

[@jdmurray]

My Mr Coffee of many, many years developed this same problem. I opened it up and tried shorting the contacts of the temperature switch using a screwdriver and pressing the brew button. The brewing cycle started because the circuit was complete, confirming that the temp switch was open. I then removed the screwdriver, cycled the power, and tried to start the brewing cycle without shorting the switch and it started! Temporarily shorting the contacts somehow unstuck the temp switch and my Mr Coffee is again brewing the same as always.

[@DrcJr77]

I had 2 that did the same. 1 worked for roughly 6 brews before failing again, but the 2nd one has continued to work now for over a year. Hopefully yours will continue to work. Great Post, thanks for sharing.

[@johntrinder3987]

[@jdrs4214]

If these coffee makers are going to be going out prematurely like this, then the best thing to do, is hop into that vehicle of yours, head on over to the Academy sports store, and buy yourself a stovetop, or camp fire percolator. No fuses, no thermostats, no waiting on parts to show up, no beeps, no error codes, and no breakdowns, when you want a nice cop of that Peets, Gloria Jeans, or Starbucks. The percolator will always work, on top of a beautiful flame.

[@markschirripa3607]

Thanks for the video. Is there such a thing as a water pump? How does the water move through the coffee maker to the brew basket?

[@DrcJr77]

no water pump, as the elements heat, the water begins to percolate which then moves up through the lines.

[@markschirripa3607]

@@DrcJr77 Thanks. Maybe that's why I could never find a water pump listed as a part for this machine (ha). In a fit of impatience, while trying to empty water out of the water holder, I smacked the bottom of the machine. I thought I had messed up the water pump with that smack. But since there is no water pump, I'm at a loss to figure out why the machine sounds the "done" tone just seconds after I turn it on and why it takes an hour to brew a few cups of coffee. I'll take any advice but if you use terms like "continuity" or "board", I won't know what you're talking about.

I'm not aware of a reset. One thing that could produce your issues ( outside of a short in switch ) would be your timer engaged. ( which would override switch ) Without troubleshooting it personally, it's hard to say. This is only an educated guess.

[@FisherCatProductions]

My thermostat would test closed (working) but was shutting the heating element down before the water tank was empty. I had to restart it once or twice to finish the cycle. I proved it by pulling the thermostat away from element so it would stay cool (closed). I could then run a full tank with no problem. CAUTION: turn it off before the tank goes empty or you can overheat the element and melt the safety fuse.

Is there a switch hooked up to the basket somehow? I also enjoy figuring out how things work and fixing them. What is that white compound you used to reattach the senor switch to the element in your repair video?

[@DrcJr77]

@@ronaldreese292 Good Morning, To answer your questions, No there is no switch nor sensor that detects basket. The only thing that makes sense is your sensor was stuck open and with time or vibration it closed. (sometimes just tapping a sensor will release the relay if stuck). The white compound is a thermal compound. This is used to help transfer heat and give a more accurate reading. This will greatly help the +/- ratio of the sensor. Also keep in mind, the 5 beep is an immediate error and failed system check. (Temp/High limit sensor) You would not get an beeps from failed elements, it just wouldn't brew. I hope that answered all your questions. I do understand your passion for knowledge. 2 thumbs up for you Sir

[@DrcJr77]

OK, if I remember correctly 3 beeps is after brew is complete. Double check filter (if it has one) and look for any taped (unpacking tape ) valves. 3 beeps means it's done brewing, or in the same sense No Water recognized It would render same error. Even if you have water. My advice is disconnect power, double check filter if it has one, check all taped valves. If all good. Well then plan B, it's probably air locked, but you shouldn't have to deal with brand new. So what you could do, Note: I don't advise this , only heard this from 3rd party.
