Jams are almost always coil sizing or coil position, not the machine. Work through these steps in order.
1. Test the motors
In the Admin Menu, open Slot Management and tap Debug next to the aisle. Keep the door open and watch: the motor should turn one full 360°, no more and no less. Test each aisle 3 times.
Step by step with screenshots: Slot Management: How to Test the Motors on the VTM Machine
An empty aisle will sound "Please contact administrator" during the test because the sensor sees nothing drop. That is normal. Wait for it to finish and keep testing. More on the sensor: Refunds and Failed Delivery
A motor that does not turn a full 360° every time is a hardware problem, not a coil problem. Contact VTM Support.
2. Set the coil position
Set the end of the coil at about the 5 to 6 o'clock position so the product does not slide out on its own. Retest for a full 360° after any change.
This video shows how to adjust coil position.
3. Match the coil size to the product
Product too big for the coil cannot rotate. Product too small lets two items creep forward and drop together. Measure the product's thickness and pick the smallest coil that is wider than it, with a few millimeters to spare. The product should sit upright and drop freely without being squeezed.
Coil | Product |
22mm | Card packs in a 3" x 4" top-loader case, some mystery products |
35mm | Slim vapes (Breeze, Fifty Bar 20K, skinny vapes), pouch tins with a Tin Lifter |
35 or 45mm | Geek Bar Pulse 15K, Raz TN9000, out of the box |
45mm | Geek Bar Pulse 25K, Raz DC25000, out of the box |
50 or 55mm | Boxed vapes like Geek Bar, Pokémon mini tins |
Depending on your configuration, the last item in a row may not fit.
Before you stock a route, test a full aisle: load the coil completely, vend it down to empty, and watch every drop clear the wall on the way down and land in the exit, also called the prize door.

This video shows how to change coils for a different product.
Pouch tins (ZYN, ALP, Lucy)
Pouch tins are too short to stand upright in a coil. They fall over, slide under the coil, and jam. Use the Tin Lifter with 35mm coils to hold them upright. Setup: Tin Lifter Installation Guide. Buy the Tin Lifter
Vending booster packs?
Booster packs need a 22mm coil, a product pusher, and a top-loader case. See Pokémon & TCG Vending: Setup, Refund Sensor, and Jams.
Still having trouble?
Retest the motor 3 times after any change and confirm a full 360° each time. Then contact VTM Support with your machine serial number, the aisle number, and whether it is one aisle or several.
