The interior lights do not turn on when the door or drawer is opened. This can be caused by burned-out halogen lamps, door sensor issues, reed switch faults, transformer problems, or a faulty control board.
| Possible Cause | How to Fix |
|---|---|
| Halogen lamp burned out | Visually inspect and replace lamp(s) |
| Door not closing properly (tall models) | Remove food obstruction or fix door hinge binding |
| Reed switch stuck closed | Verify actuator extends when drawer opens; replace reed switch assembly if not |
| Reed switch unplugged/faulty | Check resistance at P2 of control panel with door shut; replace if open |
| Thermal cut-out faulty (tall models) | Check resistance with power off (must be cool); replace upper control panel assembly if open |
| Interlock switch faulty (tall models) | Check resistance while depressed; replace upper control panel assembly if open |
| Transformer primary faulty | Check resistance across orange & white wires at P7 & P5; replace transformer + control board |
| Transformer secondary faulty (tall) | Check for 15VAC across P11 and pink wire; replace transformer if absent |
| Transformer secondary faulty (base) | Check for 15VAC at light socket; replace transformer if absent |
| Control board faulty | Check for 115V across P6 & P5; repair wiring if no voltage |
