I have a Maytag MSD2556A and the compressor is in lock rotor ..
I ordered a compressor from Appliance Parts Pros and they shipped me a Embraco FGS 100 HAW and the old compressor number is Embraco EGS 100 HLC. The old compressor doesn't have oil cooler connections but the new one does. I talked to a sales associate for your company but she says that that compressor is for the unit.
Maybe the oil cooler connections are for other models that have that option on the refrigerator but mine doesn't.
My question is can I just seal off the oil cooler connection and have no problems.
Thank You in advance

The oil cooler should have rubber plugs over them, you should not have to do anything with them, only if your gonna use them

wouldnt the refrigerant leak out if you didnt seal them off

[abadfish66]

They are factory sealed out of the box. If they have the rubber caps over the tubes, the refrigerant will not leak out. Some manufacturers put rubber caps, and some put rubber plugs. You leave the plugs or caps if you don't need to braze any copper lines to them.

Also I ohm-ed out the connector that is suppose to go over the start and run terminals and they ohm together. Sup with that? I haven't installed a small compressor for a refrigerator in years but I guess they have changed things.It has three male terminals on the other side. They gave me a start device that I guess is suppose to go in conjunction with the connector. Not sure how the part would work properly on the terminals if they ohm together. Meaning I have continuity between them. As a matter of fact all three terminals have continuity between them all.

Hope this made sense

You will get continuity between all terminals, You have to do an ohm reading. common to run and common to start... ohms added together should equal the resistance between run to start, if that checks out your compressor is good.

What should my low side pressure readings be? It is using R134A

[abadfish66]

2 to 4 inches in that range will be good

[marster37]

You mean psi?

[abadfish66]

No, 2-4 inches is 1-2 lines below 0 on the 134 guage.Each line represents 2 inches. Any thing below zero is called inches of mercury. So when I refer to inches it means below zero. Anything above that would be an over charge. When you hook the guage to your running compressor, you should read about 27 to 28 inches. You can charge the system knowing this info.
