My spinner dont want to spin what can be wrong. its coming on but not spinning

No spin,orlitespintry these:bare in mind that many times there is no spin it can be due to a clogged water pump so check it for debris and or broken propeller.

Other items to checkUsing a multi meter check for continuity the door switch, which when bad may not allow agitation or spin.Bare in mindthelid switchassembly can fail either mechanically or electrically.
Check the clutch,motor coupler, brake assembly,transmission,and mode shifter or actuator. one way to check for slipping is to get under the machine after a spin cycle ( this is if u get alilspin but not much leaving clothes still wet) mix in a spray bottle alilwater and some dish detergent, then spray it on the clutch assembly ( the metal round pc. Connected to thetranny) if it sizzles and steams up then u know its bad and slipping. Another way to check clutch if u get no spin at all? Is to take it out and useurhand to try and turn the inner spring assembly pushing it around the inside? If its very easy, it BAD should be hard to push by hand.

Or try the hand test:

If no hammering sound has ever been heard out of this machine, one of the unofficial tests we professionalappliantologistswill do in the field is called the Hand Test. WARNING:This test is not sanctioned by Whirlpool Corporation; it involves bypassing safety equipment and then putting your hand on and near rotating machinery which could result in injury, dismemberment, disfigurement, disembowelment, mangling, hideous screaming, and a ****** *****. Proceed at your own risk! Have a nice day.

- put the timer on a spin cycle and open the lid- grab the inner basket with maybe 30% to 40% of your hand strength with your left hand- turn on the machine and bypass the lid switch by depressing the lid switch with a key until the machine begins to spin- if the clutch is engaging properly, the basket should immediately begin to spin and slip through your hand- if it takes very little force to stop the tub from spinning, the clutch needs to be replaced.

Next check the motor coupler which engages the tub andtrannyto the motor. ( if its bad u usually get no wash or spin or very little of either)

Nextif belt drivencheck for a loose, worn or broken belt.And on some models there is no clutch but rather what is called asplutch. And a MODE shifter. These can go bad and effect the spin cycle.

On some front load models u may need to check the STATOR assembly.
The stator is essentially one half of a motor, it interacts with the tub by creating a strong electro-magnet. If the stator burns out the washer won't spin or agitate. Check the stator for continuity. This part is often misdiagnosed.
Sometimes a no spin machine can be due to a pluggedwaterpumphose or obstructed water pump propeller. Check these by eye and hand.And in some models check with a meter for continuity and voltage.

LID SWITCH TEST-next step is toremove the cabinetand jumper thelid switchharness (tan to gray). Put the unit in spin and watch the shiny metal clutch disc that is on top of the transmission where the shaft comes out. If the machine starts and runs in spin, check to see if the disc is spinning. If it is, then the problem isnot in thegearcase- look for trouble in theclutch,basket driveor thetub drive block

If, on the other hand, the disc is NOT spinning, check for a problem withthe motor drive coupleror one of its retainers. This washer doesn't have a belt. Instead, the motor is directly coupled to thegearcaseby a drive coupler; that's why it's called adirect drive washer.
