Washer is acting erratic. spin cycle works sometimes. stops half way through cycle sometimes. got a new belt. what's next? pump or timer. both are spendy $ thanks. frigidaire FTR630ASO

Try checking the door latch and sensor.

I have had similar situation with my top load washer over the years. It has been the timer 3 times and the water pump 1 time.
How I came up with it being the timer. The knob which you set it on the type wash you want. Put it on a different cycle and see if it completes the wash cycle. example if my washer is not working when I put it on heavy wash cycle I might put it on the casual wash cycle. If you change the wash cycle and it goes through the complete cycle it is probably the timer which is part of the knob you change for different wash cycles with.
If it stops when it is time to empty the tub on all cycles it may be the water pump which empties the tub. The one time I had a problem with the water pump it was a small piece of coal had the pump locked up. I never figured how it got out of the tub and to the pump but I put it back together and it worked fine.
It should not go into the spin cycle if the tub is full of water.
Two of the timers I bought cost 40 - 60 dollars. One was 140 dollars I bought a new washer that time because the washer only cost 220 dollars.

Hi:
Your washer does not have a belt. It has a transmission, and they seem not to fail very often. Usually, the problem lies with the timer or some other switch. What exactly happens when your spin cycle comes around? Normally, after the wash cycle, the machine stops, then the spin cycle starts in the opposite rotation. The first thing that happens is the water is pumped out, then as the speed increases, the spinning throws the rest of the water out of your clothes. If your machine does pump down the water, but doesn't spin fast, then you might have a transmission problem, but if it also fails to pump out the water, you could have a timer or switch problem, as some machines won't spin with the lid open, and if the switch is broken, the machine thinks the lid is open.

Check to see if there's something stuck inside the pump or the drain hose connected to the pump (pump is usually located at the bottom and towards the back of the washing machine).

If the drain line isn't clogged, you may have a problem with the water pump such as a frozen pulley or a broken impeller. If that's the case replace the water pump. Note: if you have a belt driven washer, check the belt(s) for cracks, as this would be a perfect time to replace the belt(s) if needed.

If all checks out ok during the above suggested inspection, replace the control board or timer module.

it will fill but won,t spin, will throw out water as if it washed, then it take water to rinse but won,t spin ,then will throw out water as if it did , but clothes are soaked

check to see if your pump is slightly plugged with a sock or ?

Your top loader should pump out in about a minute and a half when totally full of water.

If pump works fine or still pumps out water, then it is a timer malfunction. Replace the timer and you should be fine. To locate a part number for your timer, refer to www3.sears.com with the model number off your washer.

Nightshade, in most cases, no spin, no drain is a lid switch problem. If you advance the timer to the spin position does it spin? If the machine is agitating you can rule out the coupler. If you are sure that it is not a lid switch problem, then you are probably looking at a bad timer....Catriver..post back.
