Possible Causes

Burned-out lamp, Loose lamp socket connection, Failed lamp driver circuit on PCB

How to Fix / Troubleshooting

Safety: Unplug and allow the unit to cool. Glass lamps can be hot and fragile.

Steps:

  • 1. Access lamp: Locate the lamp cover inside the cavity (if your Sunbeam model has one). Remove any screws or clips holding the cover.
  • 2. Inspect lamp: Check if the filament is broken or the LED module is discolored. Replace with the correct type specified by Sunbeam.
  • 3. Check socket: Ensure the lamp is seated firmly and that the socket wires are intact.
  • 4. Driver circuit: If a new lamp does not work, the lamp driver on the PCB may be faulty; this typically requires PCB replacement.
