Is there a way to check the mode shifter to see if it is working properly?
Answer Hello Ed. You can ohm out the shifter. You will want to check the resistance value of the mode shifter and not continuity. The resistance should be 98 Ohms at room temperature of 77 degrees. You will also want to test the motor for voltages. The voltage readings should be as follows: Note: All electrical testing is done at harness plugs. Voltage readings: C2 Pin 1 = Gnd C2 Pin 3 = N C2 Pin 5 to Pin 3 = 120 VAC C2 Pin 6 to Pin 3 = 120 VAC with lid switch closed C7 Pin 1 to Pin 2 = 135 VDC** C7 Pin 1 to Pin 2 = 30 VDC** C4 Pin 5 to Pin 1 = 0 VDC* C4 Pin 5 to Pin 2 = 0 VDC* C4 Pin 5 to Pin 3 = 12 VDC* C4 Pin 5 to Pin 4 = 12 VDC* * Place washer in fi eld service mode spin test (Knob Position 9). If 12 VDC is present at specifi ed pins, main control is OK. If motor runs in spin test, inverter, motor and wiring harness are OK. ** 135 VDC is present for approximately 15 seconds at the beginning of the agitate program. 30 VDC is present during the remainder of the agitate cycle. Caution: If the mode shifter coil is open, C7 Pin 1 to Pin 2 can measure as high as 300 VDC. MAIN CONTROL BOARD C2 C7 C4 Voltage readings in fi eld service mode agitate low test (Knob Position 6): C4 Pin 5 to Pin 1 = 12 VDC C4 Pin 5 to Pin 2 = 12 VDC C4 Pin 5 to Pin 3 = 0 VDC C4 Pin 5 to Pin 4 = 0 VDC Voltage readings in fi eld service mode agitate high test (Knob Position 7): C4 Pin 5 to Pin 1 = 12 VDC C4 Pin 5 to Pin 2 = 0 VDC C4 Pin 5 to Pin 3 = 12 VDC C4 Pin 5 to Pin 4 = 0 VDC
What is the function of the mode shifter?
Answer Hello Matthew,
The motor is connected by a belt to the shaft and mode shifter assembly. By energizing or deenergizing a coil, the mode shifter assembly engages or disengages the shaft and tube. This allows for agitation and spin cycle modes. The shaft and mode shifter assembly consists of the shaft and tube, mode shifter cam, and mode shifter coil. It operates in 2 distinct modes, spin and agitation. The shaft and tube transfers power to the wash system. Motor power is transmitted to the shaft and tube from the drive belt to the drive pulley. The drive pulley is attached to one end of the agitator shaft and the agitator is attached to the other. The tube is fixed to the washer basket at all times. The mode shifter changes the shaft and tube from spin to agitation. In agitation mode, the tube is fixed to the platform and the agitator shaft rotates freely. In spin mode, the agitator shaft is fixed to the tube and both rotate together.
My machine will do everything but spin. Any suggestions?
Answer Hello Matthew,
This sounds like a bad lid switch WH12X10334. WLRE4500G0WW
I changed the shifter coil with a new one that you guys sent me now the washer won't spin or agitate it will go thru the cycles without any movement could the part be defective or something else needs to be changed it used to work fine before the repair a little noise but that was all
Answer Juan, You'll need to check and make sure the drive pulley is properly installed and torqued to the proper tightness. Check and make sure the spring loaded cam moves freely up and down. Then you want to run the washer and observe the LEED light on the top right side of the motor, the LED blinks a certain pattern, depending on the issue. If you need more assistance please include a e mail address, so we can send you illustrated information.
My machine has a metallic clicking sound while agitating, it's pretty loud. When spin cycle comes on click goes away but a rattling noise comes up that just sounds like something loose. My guess is mode selector is damaged. What you think?
Answer Mrmagoo, We agree, checking or replacing the mode shifter would be a good starting point. " Once the Mode Shifter Agitate Program has completed (18 seconds), agitation begins. During agitation, the inverter continues to supply 30 VDC (PWM) to the mode shifter coil. This voltage is sufficient to hold the mode shifter cam away from the drive pulley throughout the remainder of the agitation cycle." If the shifter coil or spring is weak the cam and drive gear could slide along the top of the drive pulley making a clicking noise.
