When the washer is started, it runs fine until it gets to rinse or spin on a medium to heavy load. It then stops and we get an lr signal. When we turn the power off and let the machine control cool (it has an area on the upper right corner of the machine control which heats up during operation), the washer will complete its cycle. I have mounted a small fan outside the rear of the control panel and it blows on the control panel--this helps on small loads. Also, I have the machine on a surge protector which we turn off when we complete our loads; otherwise the machine control continues to stay warm. Do I need to replace the machine control or the assembly motor control?
Answer Berry, You most likely have an issue with the motor control board 22004473 (depending on serial number).It is normal for the control panel to get "warm" There is a transformer mounted to the Machine control board 22004488 (depending on serial number) that is "active" as long as there is power supplied to the washer, it will get warm. The "LR" code in short means the machine control board, is not "seeing" the motor run, quite often this is due to a weak or loose connection at the JP4 connector on the motor control board, or the P2 connector on the machine control board. To diagnose the issue, you'll need a multimeter that reads DCV and check for 0 to 5 VDC acroos the yellow(pin#1) and blue(pin#3) on the P2 connector while the washer is in a agitate mode. Then check for an increase in DCV across the same wires in the spin cycle(voltage will increase to 20-24 VDC then reduce down to approximately 12 VDC when the machine reaces the full spin speed). If you check and do not have any loose connections, the approximate voltages are present at the P2 connector, then the machine control board is at fault. If you do not have the voltages, then the motor control board is at fault.
washer machine power lights up but when we try to start machine wont start cycle and door locks is it the control panel motherboard problem
Answer Frank, Yes the machine control board could be the issue,there are several possibilities depending on the serial number of your washer. but you don't want to start there. Several things need to occur for the washer to operate, if the control board does not see a signal back from one of the components, it usually shuts itself off. You should consider conducting the tests and board output and inputs programs through the control board, before you replace parts unnecessarily. We'll send you some information that should help you out.
Washer will agitate fine, but when it comes time to spin I get the LR code. in the service mode in quick spin test, the motor spins slow and I get 00 for the rpm readout. In motor control board output test, the motor spins but still has 00 for rpm readout. Also membrane pad check test does not work.
Answer Hi Bill. Since LR is a locked rotor code, make sure you can freely spin the inner basket by hand with the door open. Remove the back cover and make sure with the belt removed, you can spin the large pulley. Make sure the rear basket bearing is not frozen. Hand spin the motor as well. remove the top and use the supplied tech sheet to ohm out the motor windings, the motor is part # 22003856. Make sure the wire connections to the motor and the control board are tight. The motor control is part # 22004473. Thank You.
