Question and Answers

Q:

whirlpool cabrio model # wed6400sw1 no power

A:

There is a possibility that you have a bad circuit breaker but that type of problem normally is caused by a short circuit in the wiring or a component inside the dryer. A service technician will normally need to examine the dryer and find that type of failure. You can schedule service through this link: Sears Home Services .

If you want to diagnose and repair this type of problem yourself, I recommend that you unplug the dryer or leave it unplugged and access the terminal block on the back of the dryer where the outlet cord is connected. Page 7 in your owner's manual/installation guide shows how to access that area. Here is a link for that manual in case you need it: Owner's Manual . Check the condition of those wires. Look for frayed or melted insulation that could be contacting the metal cabinet. If you find no problems, then I recommend that you use a volt/ohm meter to check for resistance between the wire connection circled in green on the first image below and the bare metal cabinet (you can use the spot where the green ground wire is connected for the bare metal cabinet ground spot). That wire circled in green is normally a black wire. You should not detect any resistance during that test. If you detect resistance, then you have a short to the metal cabinet in that side of the dryer electrical circuit. The second image below shows a wiring diagram with a portion of that L1 side of the circuit in the dryer traced in green. You can also check for resistance between the black and the red connections on that terminal block (the terminals circled in red and green). Resistance detected during that check would indicated that you have wires shorted between the L1 and the L2 circuits in the dryer (the red and green circuits traced on the wiring diagram below). You can also check for resistance between the red terminal and the cabinet ground as described above for the black wire connection. Since the breaker is tripping right away when you plug the dryer in, you will probably detect some resistance through one of the above tests. If you do, then you may be able to check the wiring in the affected circuit and determine the cause of your problem. I provided some access information in the 3rd and 4th images. As noted above, be sure that you unplug the dryer or leave it unplugged when accessing internal components.

Q:

Why won't my Whirlpool dryer start?

A:

If you hear a faint click when the Start button is pushed then the most likely failure is the thermal fuse. If you do not hear a faint click when the Start button is pushed then the failure could be one of the following:

  • Control board
  • Door switch
  • Loose wire connection
  • Broken drive belt
  • Motor
  • User interface

You will need an OHM meter in order to diagnose the failure.

I added the troubleshooting steps in the image below. NOTE: Disconnect the power cord from the power source before servicing the dryer.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website: Sears Home Services .

Q:

I have a whirlpool dryer md # WED6400SW1 and all power is good, but when i press start, it just clicks. i think the eletricial board is bad P/N W10118243.

A:

Since you hear that click, your symptoms suggest that the relay on that control board is probably working properly. I provided a wiring diagram in the image below. Before you replace that control board, I recommend that you check the thermal fuse and the drive belt. One of those components could be preventing the dryer from running.

I recommend that you check that thermal fuse first. You can access that fuse by unplugging the dryer and removing the back panel. The location of that thermal fuse is shown in the second image. Here is a repair video that shows how to check that fuse using a volt/ohm meter: Thermal Fuse Testing . If that thermal fuse is blown, it will need to be replaced. You can order that part from the Sears PartsDirect website. The part number is 3392519. Here is a direct link for that part: Thermal Fuse .

If that thermal fuse is okay, you can check the drive belt. If that drive belt is broken, the motor will not run. There is a switch that will prevent the motor from getting voltage if that belt is broken. The third image below shows how to open the cabinet. You can unplug the dryer and check the drive belt using the information in that image. If that belt is broken, it will need to be replaced. I provided the routing for that belt in the 4th image.

If the belt and the thermal fuse are both okay, you could have a wiring failure or a bad drive motor. I recommend that you unplug the dryer and access that machine control board in the console. Check the resistance through the circuit that is marked in red on the 5th image. You will need to check that resistance through the tan wire on the P8 connector pin 4 to the blue wire on the P9 pin 1. You should measure several ohms of resistance through that circuit. If it is "open" then you either have a wiring failure or a failed drive motor. If you measure several ohms of resistance through that circuit then you will probably need to replace that control board (part W10111616). Your details indicate that you are seeing W10118243 as the part number for the machine control board. The parts information that I see shows that the replacement part number for the machine control board is W10111616. The original part number for that control was W10111607.

I hope that this information helps. If you need more assistance, reply with additional details.
