Washer Burning up new Belts...Please offer your advice Brand: Maytag Model Number: LAT8714AAM Age: More than 10 years Hello, thanks in advance to anyone who can give me advice.
I've been wrestling with this washer for a few days now. Here is what I did:
Started up a load of laundry and the Washer would agitate just fine, then when switching to the next cycle (the motor reverses spin direction) the motor will hum and then shut itself off. I assume this is the thermal-fuse protection since the motor was experiencing some excessive resistance. So, I tilted the machine back and inspected the belts, the pump belt was worn and burned in a couple spots, so I changed both belts (belts 11124 and 11125 from the appliance parts repair store - not Maytag branded belts but approved replacements specific to the Maytag washer) and adjusted the belt tension (1/4" gap on pump belt when squeezed between fingers at belt midpoint). The washer now worked fine through all cycles, but in the spin mode when the motor drive belt is supposed to be slipping along the motor pulley, there is friction and it starts to heat up the drive belt and it smokes badly and starts melting the drive belt (11125).
The glide springs at the base of the motor seem fine, the motor has about 1" to 1.5" of travel along the slider and it is very smooth, the motor will glide just fine and when no belts are installed the glide springs snap it right back to its resting place. However, when the drive belt (11125) is installed, the motor does not have much range of travel on the sliders, maybe 1/2" total travel range. Is this normal, or does this tell me my replacement drive belt (11125) is too short?
My question: when the motor is spinning in the direction in which the drive belt is intended to slip, should the drive belt be slowly spinning, or should it be static with very minimal contact on the motor pulley? When my washer is in spin cycle and the drive belt is supposed to be either static or slipping or barely turning, i can look underneath with a flashlight and there is still some friction between the motor pulley and the drive belt, this is what is melting the drive belt. So, should the drive belt come loose during the spin cycle so as not to touch the motor pulley at all? If that is the intent, then I think my replacement belt 11125 is slightly too short since when this belt is mounted the motor does not have much range of travel on its glides, therefore when in spin cycle the motor pulley to drive belt interface has excessive friction.
So, my main question is: When in spin cycle what should the drive belt be doing? Should it be 100% limp and not at all contacting the mating surface of the motor pulley, or should it turn slightly? I have burned up 3 of these drive belts so far, I was thinking my pump belt tension setting was affecting the drive belt, but I keep adjusting the pump belt tension and it is not helping. Any advice would be helpful to me.
Also, I removed the motor pulley (two pulleys mounted to each other). The larger pulley had a huge build-up of burned up belt/rubber. I lightly ground the pulley grooves with a wire wheel and the pulley now looks like new and had a very smooth finish. I figured now the whole set-up would work fine since maybe the gunked up pulley walls were chewing up the drive belt, but no luck, it ate through another drive belt just like before because while the spin cycle was running the drive belt to pulley surface has too much friction i think, it starts to smoke and melt and fills the room with rubber smoke. The surface of the pulley is smooth, there are no chips or burrs that could cause excessive belt wear. Could it be that I need a longer drive belt so that when the motor slides toward the drum (during spin cycle) there will be less tension on the drive belt?
Sorry for a long post, but I need some serious advice and all the burnt belt smoke has gone to my brain! Thank you. |
