I purchased this 1500W 3-in-1 Bubble Fog Machine from Amazon and had a problem with the bubble/fobble system not working.

The machine powered on and the controls appeared to work, but the bubble section had no pump or fan operation.

After troubleshooting the machine, I found a problem with the 12V 60W power supply used for the bubble system. The original power supply was only producing around 4–5 volts instead of 12 volts.

While installing/testing a replacement power supply, I also discovered that the output wiring from the factory was reversed. The wire colors did not match the correct positive and negative connections.

In this video I show the inside of the machine, where the 12V power supply is located, how I tested it, the wiring problem I found, and how I confirmed the bubble system worked using an external 12V power supply.

Machine: BOPRCSH 1500W Bubble Fog Machine / Fog Filled Bubble Machine
Features: Fog + Bubbles + RGBW LED Lighting
Control: Manual / External Receiver / DMX512
Rated Fog Heater Power: 1500W
Bubble-system power supply: 12V 60W

Important: Disconnect AC power before opening or servicing the machine. The unit contains exposed line-voltage components. Verify polarity with a multimeter rather than relying only on wire colors.
