Possible Causes

How to Fix / Troubleshooting

Safety: Unplug the unit before touching the switch housing or opening the base.

  • External check: Gently wiggle the switch. If the light flickers or the unit powers off/on with slight movement, the switch or its connections are suspect.
  • Internal inspection:
    • Remove the bottom cover.
    • Inspect the on/off rocker switch terminals for loose connectors. Tighten or crimp as needed.
    • If the switch body is cracked or discolored, replace the switch.
  • Replacement: Install a new rocker switch with the same rating and terminal layout. Transfer wires one by one to avoid miswiring.
