For Whirlpool Internal Unbalance Switch (Part Number: OEM18019077)

Joe Bag Of Donuts for Model Number whirlpool cabrio # WTW6200SW1

this is 13 yrs old washer, everything is happening now. Here we go,1st replaced the basket hub,2nd suspension rod kit, last, bearing and tub seal. Now the washer is quiet, but still, get a banging side to side. Now it won't finish the wash cycle, always getting a UL code... Lift the lid, straighten all that's in the tub, run again for a couple of minutes, and UL code and this happens when it goes into a spin cycle and as I look in the back if the washer I see that it moves front to back and bangs... What I do now to get to finish the cycle is hold the 2 back suspension rods and even the load to complete the end cycle or the UL code comes on again and this is driving me crazy. I leveled the washer, which has been on a tile floor and rechecked, perfect. I lost on this issue. Now, what recourse do I have now?????

Joe, If holding the suspension rods to allow the unit to spin then this would be an issue with the suspension rods that would need to be replaced.

Brian, the unbalanced lever WP22001969 will need to be inspected for any broken parts or obstructions that may be preventing it from resetting the lid switch WP22004243 properly. The counterbalance ring WPW10860268 and damper pads 203956 should be inspected for excessive wear or failure as this can cause the unbalance lever to activate and stop the unit.

Kristy, The inertial unbalance switch is located on the upper right-hand side of the outer tub, in front of the top concrete weight.

Matt, There is not a balance switch for this unit and you will want to check to make sure that the hub nut is not loose or broken, also check to make sure that the splutch is not loose or damaged.

Hello James, The INERTIAL - UNBALANCE Switch is on the right side of the outer tub assembly right next to the TUB DISPLACEMENT Switch. You can test through the complete out of balance circuit from the machine control board terminal P3-2 to terminal P3-4. This should be done with power disconnected and the harness unplugged and testing on the harness, not the board. If there is a microswitch on the left rear shock, it has been discontinued and should be bypassed as per the manufacturer. Use of the units' wiring diagram is very useful in the diagnosis of this machine. This should be located in the control panel on the unit.

Stephen, The issue with the unit showing a LR error is a locked rotor. You will want to perform the diagnostics motor/motor control test, check for loose wire connections and check for binded spinner shaft bearings.

Melinfab, It would not make any difference in regards to which connection goes to which terminal.

Doug, The nomenclature in the parts order screen is incorrect. This particular switch is called an "inertia" off balance switch. No you should not be able to "push in" on the cylinder of the switch. It actually contains a rolling ball that activates the limit switch that is mounted to the assembly. If you dismount the assembly, and shake it, you should hear and feel the motion of the slide.

Tim, The issue would most likely be caused by the door lock spin enable switch in the lock assembly that has failed. If this switch is faulty then the unit will not enter the high speed spin.
