To test a switch with a certain marking, mark and disconnect all the wires. Usually the terminals on the outside of the timer are stamped or printed with the color of the wire that is supposed to attach to it. Any wiring enclosed by a shaded or dotted box is internal to a switch assembly and must be tested as described in section 6-3(a) or (b). It may also be the timer, but whatever it is, it should be clearly marked on the diagram. If you see dotted or shaded lines around a group of wires, this is a switch assembly for example, a pushbutton selector switch assembly or a relay. If two wires cross on the diagram without a black dot where they cross, they are not connected. The small black circles indicate places where one wire is connected to the other. These are places where you can disconnect the wire from the component for testing purposes. The small white circles all over the diagram are terminals. The wiring and switches that are shown as thick lines are inside of the timer. Notice that in some parts of the diagram, the lines are thicker than in other parts. For example BU-W means Blue with a white stripe, T/R means tan with a red stripe.Ī few notes about reading a wiring diagram: A wire color with a dash or a slash means - with a - stripe. Black is usually abbreviated BK, blue is usually BU. For example, Y means a yellow wire, V means Violet, R means red, LBU means light blue. Wire colors are abbreviated and shown next to each wire. The symbols used to represent each component are pretty universal.

If you already know how to read a wiring diagram, you can skip this section.Įach component should be labelled clearly on your diagram. Either way, you must remove the door panel to get to it as described in section 5-2. Usually your wiring diagram is either pasted to the inside of the door panel, or else contained in a plastic pouch inside the door itself. It is ESPECIALLY important in diagnosing a bad timer. Sometimes you just need to find out what color wire to look for to test a component. Sometimes you need to read a wiring diagram, to make sure you are not forgetting to check something. Since they can get a volume discount on the part, it will PROBABLY end up costing you not much more than trying to do it yourself.

So I know this will be controversial, and you will SELDOM hear me say this, but my PRACTICAL advice is this: if you have a problem that you think you've traced to the electronic controls in a machine, call a professional service technician to fix it. You have no interest in owning a hundred-dollar circuit board that you don't need, and can't return. However, if you're a DIY'er, it's a BIG problem. and use it on the next one of these machines that you see. You can just yank the circuit board back out. If you're a professional technician, that's not a problem. Meaning that if you didn't guess correctly, you just ate a hundred-dollar circuit board, and your machine still has the same problem that needs fixing. And being electrical parts, they are usually not returnable. Unfortunately, circuit boards are not cheap. It's just simply much faster and easier to change out a circuit board and see if the machine works, than it is to try to figure out what component of that board has failed. Wanna know a secret? For professionals, an awful lot of diagnosis is done by guessing ESPECIALLY with electronic components.
