Mike M for Model Number Amana NFW7200TW Power to the pump motor is intermittent. Pump motor (including resistance on windings) and wire harness check out perfectly. Voltage from Pin#1 of CN5 and Pin#6 of CN10 reads 117V only very infrequently and without consistent sequence processing (e.g., opening door, re-seating wire connections, etc.). I have noticed, however, that when I'm in Service Mode/Board Output Test and set to test the pump (Quick Wash on rotary cycle selector) the voltage will jump from "0" to a random voltage anywhere from 40V-60V for a very brief moment and then fall back to "0" again when the pump does NOT work. When it DOES work, the voltage immediately jumps to 117V. Only rarely can I toggle the correct voltage back and forth successfully by hitting the Rotary Cycle Selector button. Other than replacing the board, is there anything else that I should check to determine whether there's any other problem?
Answer Mike, Based on your testing, this issue does sound like the control board is faulty and would need to be replaced. Read More... Answered by AppliancePartsPros.com | Thursday, October 2, 2014
