Front Loading Frigidaire Timer or Control Board?

I have a front loading Frigidaire model FWTR647GHS0 that suddenly quit tumbling in all cycles. Searching online, I found a recommendation to check the fuse in the Speed Control Panel. Mine was burned out, so I bought a replacement and installed it. Immediately after trying to start a wash cycle, the fuse burned out. That is when I discovered the Technical Data Sheet envelope taped to the inside of the cabinet. I went through all of the steps for diagnosing a motor not running, and here are the results:

  1. Good Power
  2. Good Door Switch
  3. Good Voltage 120Vac
  4. Pin 1-pin 5 120 Vac
    Pin 2-pin 5 120 Vac
    Pin 6-pin 5 44.8 Vac
    Pin 10-pin 5 120 Vac
    I wasn’t sure about where to find the timer contacts, or the exact way I was supposed to test them, but I did notice on the WiringDiagram that 1C, 3C, 5C, and 7C are all connected to the YEL/BLK wire on the WHITE timer plug. So I inserted my volt meter contacts intothe back of the white plug to do the timer contact tests.
    ELECTRICAL POWER DISCONNECTED / TIMER SWITCH PULLED OUT
    1C YEL/BLK-1B BLUE Continuity
    3C YEL/BLK-3B PINK/BLK Continuity
    5C YEL/BLK-5B WHT/RED Open
    7C YEL/BLK-7B BRN Continuity
    ELECTRICAL POWER CONNECTED / TIMER SWITCH PULLED OUT
    1C-1B .001 Vac
    3C-3B .001 Vac
    5C-5B 33.4 Vac
    7C-7B .001 Vac
  5. Fuse bad
  6. Pin 1-pin 2 1.397 Meg Ohms
    Pin 2-pin 3 1.414 Meg Ohms
    Pin 3-pin 1 3.15 Meg Ohms
    These are all supposed to be 3 Meg Ohms +/- 10%
  7. Pin 1-pin 2 2.6 Ohms
    Pin 2-pin 3 2.6 Ohms
    Pin 3-pin 1 2.6 Ohms
    These are all supposed to be 2.6 Ohms +/- 7%

I’m quite sure I wouldn’t have both the Speed Control Board and the Timer go bad at the same time, but I’m not sure which is causing the problem, and what is causing the fuse to burn out.

Any help would be greatly appreciated.

Look and test all of the wires coming from the control to the speed control board. You are looking for a short, or a fraying or something that would cause excess voltage.

If you cannot find a problem, try replacing the speed control board. If you buy from this site and the board does not fix the problem you can return it, see the returns policy for details and conditions.

Thanks for the suggestions.
I did look at the return ploicy,and it says that parts must be returned in the same condition. So if I install the Speed Control Panel, and the fuse blows, would that void my ability to return it?

I don’t know. Those of us who reply on this Forum are volunteers and not associated with APP parts operations. I would call them and explain the isssue, reference these posting and see what they say. They are very accomodating and my guess is they will take it back, but confirm before you order.
