Refrigerator switches

[jdc1]

There are two separate switches at the top jamb of my refrigerator. One says "Low Ambient", the other "Climate Control".
Thinking my door light switch was bad (stayed on), I replaced it. Same scenario appeared. So, I played with the two switches on the jamb. Low and behold, the interior light goes off as intended when the "Low Ambient" switch is turned off.
Under what conditions should these switches be in the "ON" or "OFF" position? I'm thinking maybe my wife or myself inadvertently turned on the "Low Ambient" switch, which in turn, kept the interior light on.
For those that need to know what make and model the fridge is....it's an old Dometic Royale (model number RM3862) with separate doors for both refrigerator and freezer. Even at 21 years old, it works perfect.

LAT keeps the light on
The other one is a heater around the door opening (to keep moisture from freezing door shut).

1. LOW AMBIENT Leaves the interior light ON to stop freezing of items stored close to the evaporator fins when outside temps are not hot. Usually items like lettuce
2. Climate control is a 12 volt heat strip in the outer metal frame around the inside metal flange where the Freezer and lower doors are. The purpose is to stop any possible condensation drops on that frame. VERY RARE for those water drops to happen.
3. LEAVE switches OFF unless you experiance the problems above. Doug

Thanks Doug.
