this is dangerest the lid switch is a safty device so the machine stop when lid is open in spin. not recomended has nothing to do with slow spin. so if your hand or loss clothing get down in drum it does not pull you in. door up open switch. when door close switch close again 1-high / 0 low computor logic no.
two: the reason it agitates and pump water works ok, is because the belt load is not as great and the condition allows it to work some what.
three: after 42yrs as a tv/appliance repairman
and my product in my store was whrlpool appliance and this is excatly what this machine is. this is a classic belt condition. in spin it has a water load plus wet clothing load is about 100 to 135lbs load. belt wear and condition makes it spin slow. ( no adjustments for belt replace only)
PS: appears that certain models have belt adj loosen motor pull back.
four: this machine requires that the transmission be loosen and pulled back on it side that is pull part of the way down.
their some spacers that have to be removed and clutch has a key that has to be removed.
five: home owner can not fix this. i will see if i can fine a drawing if i still have the manual.
if you do not know what your doing your done clutch is subject to damage real easy. do not pry on clutch to open it will bend. effiency
will be lost.
i have the road manual only will post shortly.
