If your appliance has a relay board (can be on main board as discussed above) that controls all components of the appliance and there is a problem check the failed component first then look for a bad solder joint.

How to fix a flat wire?

To fix this you can solder a jumper wire onto the board to replace the flat broken wire. To do this, trace the wire back to the nearest solder joint then trace back the opposite way to the nearest solder joint. You will then solder a jumper wire between these two solder joints. To do this, melt off the existing solder off of each joint, and then find a small wire that you can wrap around the pin. Solid wires are easier to handle but it can be hard to find a small solid wire so you can use stranded wire if you twist it tightly. Once you have the wire wrapped around the pin, use the same soldering technique outlined in the above paragraphs and the video.
