We have had some issues with the Fan Motor in some units. Here’s how you know if it’s happening to yours!
We have had some issues with the fan motor failing to turn at a constant speed. It has cropped up in about 30 roasters (out of 1800 units or so!).
It seems to happen after 30-50 roasts or more, which is why our QC team didn’t catch it. This video demonstrates the sound of a good fan motor and a bad one, and tells you what to do to get roasting again!
If you’re Popper roaster starts sounding like the Defect Unit I show in this video, STOP using it though! And email firstname.lastname@example.org for more…
If the fan knob starts to feel like it is not “clicking” into position at Off, Low, or High, it might break soon…
If the fan knob is turned past the Off or the High position stops, it can break. When it breaks it spins freely on the post, so it can’t be used to turn the machine on or off, or change air speed.. Bummer.
This is caused by being handled too rough, turned too hard, especially when the user believes the range of the Fan knob is the same as the Heat knob, which turns in a 180 degree arc. It isn’t. The fan knob turns in a 90 degree range. But honestly this would be less of an issue if the way the knob grabbed the post was stronger. We will fix that in the next manufacturing run!
The good news is that it doesn’t damage the post that the knob attaches too, nor the function of the machine … just the knob itself.
The bad news is that the knob doesn’t just pull off the post from the front of the machine. It is “trapped” behind the front plastic panel. So you have to take the machine apart a bit to get at the knob. You can either get a used replacement knob from us , or even just opt to take it off and use the machine by turning the post directly. It also seems that other types of knobs will fit on this “half moon” shaped post. Get creative!
Also, getting at the knob isn’t hard, you just need one small screwdriver and the rest is pretty easy. I can do it in 5 minutes, but it probably took 15 minutes the first time to complete this repair. See below for the video version of this repair or follow this link to see on youtube directly
The latest video is a bit of candid talk and a take-part / deconstruction of Popper to show the build and insides. I can’t recommend modifying it in any way, but I do want to show how it is built, the components, and how I test the units.
