ADC Coffee Maker Powers On But No Heat Repaired
A usual morning, woke up and prepared the coffee maker to make coffee, pushed the power button on and then started getting reading to take my kid to school. Usually I could smell the coffee being made but today, I could not smell it, something was wrong. I went to check it out. I could see the power button on but there was no coffee coming down. I was really frustrated.
I had this machine for over three years now and it is a very good coffee maker but on that morning I had to make coffee the old fashion way and of course that took extra time for the coffee to be ready.
Anyway, I took the coffee maker to my shop for repair. Here is the story.
Since the water was not coming down into the coffee pot of the machine, the problem could be the heating element itself and that is where I headed first. I checked the two thermal fuses on the bottom but they were fine. I checked heating element resistance and that also checked fine.
Since there was nothing wrong in that area I headed next to the power board itself. I did not go there first because the power button on the machine was on and I did not suspect anything wrong power wise.
The only bad part I could find on that board was the .46UF capacitor; its capacitance was measuring below that value and it had to be replaced.
I found the same exact capacitor in my shop and right away replaced it and hoped for the best.
I do not know if you can see the steam in the photo because I added some water on the heating plate and it started to evaporate.
Anyway it was repaired and I was very happy. I am looking forward to next morning to enjoy a nice cup of coffee and to that I could say
