Topic tags/keywords: question sander

I have a 3 year old Jet Performax 16-32 plus drum sander, the conveyor belt motor controller failed and I’m wondering if anyone know of a more affordable option than the $370 +tax that Jet sells. In past forums I’ve seen some have upgraded older models with the sand smart controller, does any one have their old controller I could buy from you or know of an after market controller to get my sander going again.

Thanks in advance

The controllers are basically a light dimmer. My Performax 16/32 died and I just replaced the triac and diac to get it working. Eventually the 120V socket for the drum motor wore out (heat) and the switch on the converyor speed control broke, so I replaced the socket and added a separate switch for the conveyor control.

So basically, if you have the ability to do some simple repairs on PCBs, you can probably fix your original controller for cheap (but inspect the connections inside first for “simple” problems before doing surgery).

I had a similar problem with my ten year old Jet 16-32 with sasndsmart. I ended up buying one from ereplacements parts for $370 because I was in the middle of a job that I was getting paid to do. I don’t know how much you searched on this site but here is a link to a lot of information. https://www.lumberjocks.com/topics/140602 Look at the photo from, dgrant, and look at two things that I found . There is a fuse to check that is marked F2 which is located in the 11:00 position above the part marked ROHS. My fuse was ok. Also look at the bottom of your board to see if there is a name of the manufacture. On the board in the post from dgrant it is located at the bottom and says ??? TECHNOLOGIES. On my board the name was GE HOW CORPORATION LTD. and located at the top.

Searching on the name lead me to this company that said it does circuit board repairs.

https://www.lektronix.com/about

When I contacted them they responded saying that they are no longer doing repairs, but the above link is what I found today . I placed the part # and this is the result. https://www.lektronix.com/equipment/ge-how-jet-001/102293. They may sell new boards also?

A friend of my needed a speed control, not a sandsmart, for on older Performex sander and looking at the back of the switch there was KBVE-041595 which lead me directly to the manufacture and I was able to buy the part for $39 instead of $130 from other online companies. If this is the style of the switch you have which is about 2 1/2” in diameter, you can go to this site https://www.galco.com/ and purchase a new one like I did for around $39 control, Here is the link to the $39 control, https://www.galco.com/scripts/cgiip.exe/wa/wcat/catalog.htm?searchbox=KBVC-14-KB , that I purchased.

Remember that your motor is probably a 90 volt DC motor. I did connect mine to my van battery and it did move very slowly so I knew my motor was ok. The controller input is 120 Volts , but the controller converts it to DC so the 90V DC gear motor will work.

Hopefully you are not in the same situation that I was and you have enough time to search for a cheaper solution.

Good info 4Wood! I have the older, non-sandsmart version without any of the motor current detection circuitry or fuse.

The key to disassembly is to diagram the wire connections before hand. Several extra connections assumably for other voltage options. You don’t want to accidentally wire it back up incorrectly!

So glad I stumbled onto this thread. Thanks 4Wood for the detailed input. I have an old ShopPro 25 that the conveyor quit on me, this is very helpful to save some cash. Many thanks

My performax 25” drum uses the same 72-2250 controller board. The fusible link on my board popped (interestingly, while there was no load on the belt drive motor). Does anyone know how I can find the spec on that PCB fuse? It makes no sense to buy a new board for $500 when I can be up-and-running with a $3 part.

Any help is greatly appreciated.
