Hi, Neighbours of mine bought a 2003 Solaris Lite T2363 (from Sunline) last year. They have a light swith (below the water heater switch next to the oven) which has 3 positions. This switch, when at the highest position, allows powers in the outlet where the microwave is plugged (inside the cabinet next to the microwave). We're assuming the lower position is the OFF position. Despite looking at all their documentation and on internet, we cannot find what the middle position is for. Does anyone have a similar trailer and know what switch I am talking about and what is its use in the middle and lower position? Thank you!
