Asked about a problem with the spin cycle. Was told the problem was in the control board. Could not find it in parts Would that be the same as the dial for selecting the wash cycle

Sears Parts Direct is one source of the parts diagrams, https://www.searspartsdirect.com/model/1vc37q1bdj-003204/lg-wm3987hw-washer-parts . See the Dispenser assembly parts diagram for the water inlet valve. If you can watch the entire cycle, try turning off the shut-off valves for the washer inlet hoses after the rinse cycle and before the dry cycle starts. Water should not flow into the washer/dryer with the shut-offs closed.

I've seen inlet valve solenoids fail in the open position or in the closed position. I've never seen a control board that sent open messages randomly. (Sometimes, there is damage to the control board or corrosion or damaged wiring that stops the control board from sending the open/closed message to the solenoid.)

I hope this helps.

E75 has nothing to do with the spin cycle, pump, door switch, or anything like that. E75 means there is an issue with your temperature sensor circuit. That is part of your control board, which means that the control board will need to be ordered and replaced to fix the E75 error code.

Sounds like the timer and control board are not communicating correctly and efficiently when in a normal cycle. You would need a professional to diagnose the control board and see if that is the only part needing replacement.

Just going on these symptoms, you may need a new control/timer.
Inside the control /timer are electrical contacts, and when your machine gets to that part of the cycle, the contacts are not closing to allow the cycle to complete.
If you have circuit board, you will perhaps need a new one of those.
If you do not, probably a control/timer assembly.
If you type "SeasPartsDIrect" into you computer's search engine, and then type your complete model number into the blank when you are asked for it, you may look at the schematic and see whether you have a control / timer or a circuit board.
God bless your efforts.

I am a service technician in grants pass oregon and i had the same problem. It told me to replace the board too. I replaced the main boad, Motor control board, door switch and cleaned all the hoses and it still didnt fix it. I had 3 other service technicians look at it ( one from sears ) And nobody could figure it out.

you need part number 12002039. its a motor/ motorcontrol kit. there have been alot of problems with this motor so maytag redisigened it

yes. the solinoid or wax motor (depending on which switch you have) has fail and is not telling control that the door is locked. replacing the switch will fix it

Open the rear panel and look for a broken belt and does the motor spins. In case motor doesn't spin, check on its tags for 115/220V. Let me know with your results,for further assistance if will be needed. Good luck!
