For Whirlpool Pcb (Mems) Sensor (Part Number: OEM18025344)

1 Answer

GW, The 3E indicates a motor failure (Over current). This means that over current is detected and the motor won't turn. You will want to check the motor windings, the speed sensor, wiring connections and control board. The tech sheet that is located in the unit will tell you how to check. Any 2 pins on the motor connector should read 11.6 ohms. Pin 1 to 2, pin 2 to 3 and pin 1 to 3 on the CN9 connector of the main control should read 11.6 ohms. If outside the range then the motor is bad.

Chuck, The error code E2 indicates that there is a stuck key on the control. You will want to unplug unit for 30 minutes. Plug back and if the code returns then you will need to replace the keypad.

Hello Danish, If you are getting proper voltage to the drain pump it may be that the vanes on the impeller are bad and you would need a new pump.

Hello Witold, If you are only getting 20 vac to the pump then you need to check the wiring. To go from 120 vac from control board and only have 20 vac then you would have a shorted wire, loose or broken connection somewhere in the wire harness and will have to trace the wire to find it.

Gary, You may be correct, power to the drain pump is from the main control board WPW10273828 But, you should run the diagnostics and board output tests first, listen, feel or observe if the drain motor runs or that you have voltage to the drain pump motor in the test mode WP34001340, before you install a control board.

John, in short, the "mems" sensor acts as an "off balanced" load system. Instead of the washer continuing to spin,based on motor torque, if there is enough movement in the cabinet,in the event of an off balance load, it will reduce speed, and attempt to re balance itself. The control board or sensor is not likely the issue. There is a remote possibility that the control board or mems sensor is bad, but very remote. it's most likeley a shock, and possibly a loose or broken spin basket support arm.

Haole for Model Number MAH6700A

I am continually getting a cycle interruption that brings up a code of 3E,and it seems to be just before a spin cycle. to get it running again, I open the door and move the clothes around then close the door, push the button to resume. Sometimes it works, when it doesn't, I can here about 5 ticks, 5 seconds more, another 5 ticks, 5 seconds then maybe 6 ticks, by the 6 or 7 set, if it doesn't start, then the chime starts and the code given is 3E. My suspicion is the spin cycle sensor is faulty because when itdoes work everything seems to be fine, the tumble motion and spin work great. It only seems to happen when it tries to do spin cycle. Again, 3E code.

Hello Haole, This sounds like a motor or motor control issue. Note the service manual I've included in the attachment. I've included a second manual which only partially applies to your unit. The manufacturers refuse to make a complete service manual on any particular unit, as they say it saves them time and money to make generalized manuals that vaguely cover multiple units. Please let us know if we can provide further assistance.

Hello Val. You need to check and see if there is any bad wires on the unit. If not, you will need to replace the electronic control WPW10273828. This is what sends power to the drain pump assembly. The sensor WP34001484 is used to detect vibration in the unit.
