2012 Reyo 25T

I recently bought a 2012 Reyo 25t. There is a switch on the side wall below the matress at the foot of the bed on the driver's side. It glows red when switched on. I can't figure out what it does. The water heater switch is on the control panel over the refrigerator.  Anybody have one and know what it does?

      The button circled.  The black above it was were i took the drawer out to see where the wires went.  They went down under the furnace.  You can see all my appliance switcges are on the control panel above the refrigerator.  

  • I wonder if it could be for electric heat on the water heater. If you want to test that make sure there is water in the heater before flipping the switch. If no water the heat element will burn out pretty quickly. 

  • That's a tough one. From it's position it looks like something they don't anticipate common use so it's probably not for overhead lights. What's in the black area right above the switch in the picture?

    It will most likely take some good old fashioned sleuthing skills. It could be an exterior light. wait until dusk or dark and walk around inside and outside and make sure no lights are on. Then switch the switch on and walk around again.

    Turn off the water heater and let the tank cool (maybe turn it off the night before you go to bed) In the morning flip the mystery switch on and check the water temp after 30 minutes. 

    Is there an outside entertainment system or plug that it might control? 

    Could it be for the water pump like for if you forgot to turn on the pump before heading to the bathroom at night?

    Are the fuses in the breaker box labeled? If so try turning on the switch so it lights up. Then pull a fuse and see if the light goes out. If the light stays on replace that fuse and pull the next one.

      1. Thanks so much for answering.  I figured that was what I would have to do. The black space is where I took the drawer out to see where the wires went and to find the hot water bypass lever. I found the leveler crawling halfway in and it was behind a support board. The wires went under the heater. I have all these switches over the refrigerator. It won't let me post pictures on the reply, but there are pictures on this thread of my switch setups.

    • The switch is below the drawer. The water tank heater is above the mattress on the wall and labeled.
