Maytag
Age

20 yr old fridge old refrigerator - Maytag MSD2556AEW.

Stopped cooling with clicking sounds from the start relay

Old relay has 3 prongs and 3 connectors and one of the connectors had a double wire( 2 orange connected together as one terminal , one only white and third one only blue)

The part number on the white start relay is 4sp1034 ( with connector markings 5 and 6, and a connector pin for the blue overload wire )

  1. What is the equivalent replacement part ?
  2. There are various replacement start relays but they have 4 prongs and connector numberings are different. How do i connect my 3 orange, white and blue connectors.
    Start capacitor and compressor are fine. Thanks for any help !

The clicking sound is the overload opening and closing. The relay normally doesn't cause the overload to open. Maytag compressors can cause it to open when they go bad.Measure the resistance of the compressor windings. Check from each pin to the compressor body/ground. Meter should indicate 1 or open.

That's where you lost me. LOL According to the parts diagram your compressor uses an overload, relay and run capacitor. The run capacitor is not necessary for the compressor to run normally. A run capacitor is installed across the start windings and run windings.

I checked the overload, compressor. Both fine
the relay has burnt black particles falling from it
and, when I shake it there is more than a rattle.
however, If you could if you could advise me on connecting the new relay ( numbering schemes)
from the picture it appears thee are more than 4 terminals( my old relay has only 3)

OK, the part in your picture (the old part), is called a "start device". The start device contains the overload and the relay. Part number W10920279 is the relay.

You still need the overload, part number WP61006295:

There are three compressor pins in a triangle configuration. The overload goes on the top pin of the triangle. The relay goes on the bottom two pins

The wires from the old start device go on the overload and relay like this:

This is the same as the picture in my last post #2
