Interior light does not turn on when the door is opened

Safety: Unplug the cabinet before working on the light or door switch.

Steps:

• Check settings: Some Transtherm models allow disabling the light. Verify that the light is not turned off via the control panel.
• Inspect door switch: Locate the door switch (plunger or magnetic reed). Press it manually and see if the light flickers. Replace the door switch if it feels loose or does not actuate.
• Check LED module: Remove the light cover and inspect the LED module for burn marks or water damage. Replace the interior LED light module if defective.
• Verify wiring: Ensure the light harness is connected firmly to the control board.

Note: LED modules are low voltage but still require the unit to be unplugged during service.
