Washer failed to spin at the end of a load. I opened the front, defeated the lid switch and put the washer in diagnostic mode. Tested the lid switch and fill switch, both working properly. Washer does everything correctly in every mode except spin. In the spin cycle it agitates. It starts with the drum movements like at the beginning of a wash to detect load size, then goes into standard agitate. In agitate the motor runs back and forth, so this is not a gear shift issue. Drain pump runs the whole time and never stops for the entire spin cycle. Gear shift between drum and agitator working correctly in other cycles. The inverter board seems OK as movement is right in all the other cycles and the LED blinks according to chart (slow blink in idle, .5 second blink when running) I suspect main board or EEPROM, but sure would like to hear a definitive diagnosis before I start throwing expensive parts at this problem. Thanks in advance for any advice.

Thanks, Eric, for the quick reply. I ran the check and found the voltages as described, at the control board and at the inverter board, right on the back of the board to make sure it wasn't a harness or connector problem. So it looks like the inverter board. I don't suppose there's a way to purchase just that board? Seems like a waste to replace a perfectly good motor ($250.00) just to get the board that's screwed to the top of it...

That's certainly a top-notch return policy, worth the price over some of the other online stores. Will order and post the results.

Thanks!
