The bottom of a Cuisinart ice cream maker come off with the proper tools. Four screws holds it in place; they aren’t all the same though. Three are standard and will turn with a normal screwdriver.
The fourth, however, is the tricky part. It’s a U-shape driver. And it fits only that shape. After you get this one, the others pulls right out.
Disassembly and Initial Inspection
After taking out the fasteners, you can peel off the cover and see what’s inside, the electrical circuit. The white plastic casing has a round hole on top that looks like a speaker and vented grilles on its rear section. Looking closely at the sides, we can see that it was manufactured by West Metric Sdn. Bhd. In China.
Voltage-wise, it says 230V/50Hz so you know whether or not it will work with your setup. Keep this handy just in case. To keep an orderly working area, lay the unit down on a cutting mat. It will help you avoid misplacing any of the smaller component while doing so.
Beside it says, “Heat Matic S90, BHD” and the model number 218035 is printed next to it. To the right of that is a black and yellow screwdriver. You might or might not have used it on the cover, but it comes in handy now as well.
Slow down when taking this apart as being too quick might wreck the electronics. When you take your time you will be able to identify all connection.
After removing the casing, you can see the motor assembly. It consists of the yellowish coil of the motor with a white plastic fan-like impeller sitting on top of it. There’s also some black wires connecting the different parts of the circuit, as well as the blade assembly near the motor.
They’re pretty tight on these things so you’ll have to be patient while you trace out all the wires. First, look at how the pieces go together. That will help you know what goes where.
The drive system is a complex one. This is what the mechanism looks like when inspected. You will notice that the metal terminals ensures good electrical contact.
You need two hands to hold the housing steady while inspecting the mechanism and metal terminals. It’s not light so it’s a bit awkward to maneuver. Be careful not to cause damage to these parts because they all appears delicate.
If you want to understand how this thing works, remove the bottom cover. Inside is an electric system that creates the churning motion of the ice cream maker. It won’t work without the motor and there is also circuitry that controls the length and speed.
Behind the white plastic shell are all the parts and systems for keeping the motor cool and preventing the buildup of to much heat. There are even vents that help airflow to cool the motor down.
Don’t panic and try to put it back together right away. In many cases it’s best to leave the thing alone until you clean it out. Over time dust and other crud will affect performance, so inspect the exposed wiring for any damage.
Fortunately, the connections appear solid, a sign of good build quality. This teardown just fulfills curiosity, since most people don’t see what goes on under the hood.
That’s what the project shows off, the tools you need for a device like this. One of them is the U-shaped screwdriver. It is necessary because most fasteners are not accessible with ordinary screwdrivers. Safety considerations should of made the manufacturers embed special screws that resist casual meddling by users. That’s fine. Respect it but explore it at the same time. Looking inside didn’t hurt anybody.
Because you were careful to follow the instructions, it went smoothly. And you didn’t cut corners when working with the electrical bits. The end product is a good example of how to take apart a Cuisinart ice cream maker, without damaging anything in the process.
It also helps you understand more about what makes this machine tick. Knowing that information can help you down the road when another part fails (then you’ll know where to begin looking).
You can put the screws back in easily if you have the proper tool for the job; the normal screws fit tight, and the weird one works like a champ with the U-shaped driver. It all goes back onto the cover snugly, and it’s just like new, except now it isn’t, because you know what’s in there.
Now it’s not just a black box anymore, but a bunch of stuff that makes it work.
