Genuine OEM replacement main PCB (printed circuit board) for the Look Solutions Power Tiny 400W handheld fog machine. This is the brain of the unit — it controls the heating element, pump timing, battery management, and all user-facing controls. When the PCB fails, the machine typically becomes non-functional or behaves unpredictably.

Signs you need a new PCB:

• Machine will not power on despite a charged battery
• Heater fails to reach temperature
• Erratic or inconsistent behavior during operation
• Controls unresponsive or behaving unexpectedly
• Pump runs when it should not, or does not run when triggered

Compatibility: Power Tiny only.

Note: Professional installation is recommended. PCB replacement involves disconnecting and reconnecting multiple internal connectors. Improper installation can damage the board or other components.
