Norcold inside light

Does anyone know what turns on the light inside the Norcold Refrig. I know their is not a manual door switch any where.At least I can’t find it. If anyone knows what turns the inside light on when you open the door. Please let me know where it is located. Mine started hanging last year. I started the icebox the last time we took a trip. The light would not come on. But when we got to the RV park it was working. Now it has sat for 3 months and when I turned the ice box on to start cooling it down . The light would not come on.

Food Compartment Lamp Switch
The reed relay switch that turns the fresh food
compartment light on and off is an integral component
of the optical control display board circuitry.
Lamp Switch Operation
The magnetic pull from a permanent magnet located
underneath the top door trim maintains the switch
contacts open (light off) when the door is fully closed.
Opening the door breaks the magnetic pull, which in
turn causes the switch contacts close (light on).

This is from the Model N821 manual

Thanks , I check it out

You might try a new light bulb before you go too far into the framework. You might be lucky.
