I need the wiring schematics for a Lakewood pace heater model 840

SOURCE: lakewood 7096 heater

Some of the newer models have a thermal fuse which may be blown. It doesn't look like a normal fuse at all. It is similar to a transistor in looks and should have continuity from one end to the other. It will be tied in to the incoming power cord inside the heater, and may be covered with rubber coating within the wire. It will look different when you notice it. Sometimes its too far down inside where the heat causes it to blow prematurely. The purpose is to cut the power to the unit in case it overheats. You can get one at radio shack for less than a couple of bucks. The older models don't normally have one, but I would suggest you put one in it if that's the case.

On the top of the switch (inside the heater) there is a common connection.....even though it looks as if it is connected (electrically), it isn't electrically affected by the switch; it's just used as a post. It's just the place where the striped wire connects to the "common" point for the heater coils (they are in a parallel). Also, while you're in there you might want to put some electrical grease on the exposed conductors.....mine had quite a bit of corrosion (which was the reason for the failure). I had to replace 3 of the female connectors.
