Paul and the Bad Bed Switch

Hi Paul, here is what I have. The first picture is from under the refrigerator. Double click on the picture and it will get bigger.

Like yours the two blue wires come out of the heater and are spliced, they both go to the one brown wire. They connect inside to the black and white wires within the brown one. There also are red and yellow wired coming out of the heater, I don’t know what the do.

The next picture is of the connections in the thermostat. Shows a red and brown wire going out the back through the wall.

In the next photo showing the back of the wall, the two wires come out (They look red in the picture)they then drop down and split and are connected to the black and white wires in the brown covered wire, (shown in the final picture) this is the wire that runs to the heater unit.

Note in this picture there is a wire that has a brown cover but is not hooked up. I tested this wire and it is connected to the switch by the bed. So it looks like they did not hook it up at all. The switch doesn’t work because it is not connected.

With the switch wire ending up right at the back of the thermostat, where would you think it should be spliced into the system?
