Frigidaire 134743500 Washer Motor Control Board OEM Part

This was the motor control board (also called the speed control board, motor control unit, or MCU in various places across the web). The repair was straightforward, except for two complications. First the old part was difficult to access in this model washer (Frigidaire Gallery Series front load washer). Instead of being easy to reach on the left side where there was space, it was sort of behind the actual motor on the right side of the housing. I spent some time trying to figure out whether is is possible to remove the side panel of the washer for easier access (I had removed the back panel), but that side appears to be structural, and can't be opened. Only one screw holds the part in place, and after removing this screw it was possible (difficult, but possible) to slide the part under the motor and remove it from through the back panel. There are 4 electrical connections. 3 of them were easy to remove and connect to the new part, the 4th was difficult. This connection is the one where there is a single wire and there is an unusual connection, sort of a large blade with a connector that looks like it should just slide off, but wouldn't. I was eventually able to get it off by loosening a metal curl with pliers, and then squeezed it again after attaching it to the new part. If I had to do this repair again, I estimate it would take 20 minutes, but since I was unsure about what would work and was being cautious about possibly breaking parts or finding easier ways, I spent around an hour working on it. I used a square bit screwdriver to remove the screws on the back panel and securing the part, however, they were all also set to work with a Philips head as well. It wasn't as easy as I hoped, but doing it myself saved quite a bit of money and wasn't actually that hard, in the end.

After much research I decided to replace the motor control board. Took about 30 min to replace. The machine has been working for about a week now.

I put the washer through the spin only cycle and I found it went from 12 minutes down to 6 minutes and then would stop. After making sure that the door lock was not the issue but making sure that it still would lock, I then checked the motor to make sure the voltages were correct with an OMs meter. I then figured it must be the control board. I received the control board in the mail, I unplugged the unit, took the back off the washer, took the motor out (easy to do by loosening a few screws) and then took the old control board out and unplugged all of the plugs from it. Then I put the new unit in and plugged the plugs back in and put it and the motor back in. I then plugged the machine back in and tried the machine and it worked perfectly!!!!!! It was easy to do.

Motor control board code. Ordered part, crossed my fingers and it worked. What helped me was having the technician's diagnostic sheet. Would not have been too confident w/o.

Love the internet! Found the error code, looked up what test to run. I pulled the motor and found it was fine, so the other option was the speed control board. I ordered the part Tuesday night and it arrived Thursday morning - I didn't even pay extra for faster shipping! I pulled the old part and connected the new one, put the motor in, and done! Washer works perfectly! Took about 20 minutes to install everything. Took longer to diagnose. So happy with the repair and especially happy with Appliance Parts Pros for such a quick delivery! THANK YOU!
