Clean1owner for Model Number FWTR647GHS0 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. I want to make sure I purchase the correct part the first time. Any help would be greatly appreciated.
Answer Hello Clean1owner. You will need to test the motor and see if it is good. Unplug the connection to the motor and test pins 4 and 5. You should read between 105 & 130 ohms. If it is outside these readings, you will need to replace the motor 134869400. If the motor is good, and you have replaced the speed controler, you will need to replace the timer. Hope this helps.
