Product review (5 stars): Glad I tried this
I have a Maytag MTB2156BE refrigerator which recently stopped working. I decided to see if I could repair it. I plugged it in with the rear cardboard panel removed, and I heard the compressor start and run for a couple of seconds then quit. I could also hear  sizzling noise coming from the relay mounted on the compressor. A little smoke came from the area of the relay.

When I looked online for a replacement relay, I figured I would replace the overload at the same time. However, the overload for my model is no longer available, so I came across a site the indicated this part would work and other sites that said it did not fit. Amazon indicated it would fit, so I gave it a try.

When I received this new start device, I removed the original run capacitor from its mount to the left of the compressor by simply removing the screw holding it in place. I then plugged the run capacitor into the W10189190 start device, and it fit perfectly.

The one issue I encountered was the size of the connectors. The original connectors were .250" (1/4 inch), and the connectors on the new start device were .110"  I didn't want to make any wiring modifications in case I need to revert back to using the original style relay/overload. So, I made up two small wiring adapters. I used two short pieces of appropriate gauge stranded copper wire with a .250 insulated male connector on one end and a .110 female connector on the other end. I did need to use some electrical tape to cover the back side of the .250 male connector that was inserted into the insulated female connector. I also taped over the end of the orange wire connector that originally went to the run capacitor.

The refrigerator is running well now.

As an additional note, I ordered this from Amazon Warehouse deals, so my total cost to fix the refrigerator was around $25 which includes the W10189190, 1 day shipping, and the connectors.
