Maytag SXS MZD2766GEQ Compressor ?

10 posts in this topic

Customer calls me and says he had a repair company come out to fix his non working Maytag SxS refrigerator. The repair person told him that he needed a new relay and overload. The repair guy told him he was going to use a relay on steroids called a 3 in 1. I asked customer which one he said RCO410. In talking with customer he said he had found some info online to test the compressor. All the tests check out, continuity between all pins on comp, and infinity when ground checking. ?. Can a compressor check ok and still be fried. Could the comp drawing to many amps, fry the comp. I was not there, of course, when the other tech placed the 3 in 1 on it. I guessing the thing was hot as hell.

 

Any help would be appreciated.

I don't want to go out and test cord the compressor if it is most likely bad, and then charge the customer for a service call.

Yes, they can test ok and be broken mechanically. I thought a relay was bad one time and kept clicking on overload. That wasn't the case. Even when it cooled down and still tripped. It ohmed out correctly as well. 3n1 relays are a no no in my book. I don't use them. I've been told they work fine on old ones though.

Also, as the varnish insulation on the compressor motor windings breaks down, it allows current to leak to ground.  The windings want a certain amount of power and so will draw the extra current to make up the difference.  That extra current draw causes more heat and this heat causes problems with the mechanical parts of the compressor-- bearings, piston, seals, etc.  

 

I agree with Bryan-- hard start kits are at best a grace period while the customer goes shopping for a new box.  You may get two weeks and then the compressor is Kentucky fried.

did the Compressor then work ?

It may have been "hot" because of the original  bad Start Relay

I belive 3 in 1's only cause damage when the Compressor is already bad, or on it's last legs..

OTOH, if the compressor was still good, it wouldn't need a hard start kit, just a replacement OEM relay.   :blinky:

 

I'm never one to question anutha brutha's beliefs.  Personally, I believe Jesus Christ is God incarnate, died on the Cross, and rose from the dead on the third day.  I would hope that no one would take me to task for that belief.  

 

However, in the spirit of academic fellowship, I offer this document from Electrolux outlining their beliefs on hard start kits:  http://appliantology.org/files/file/827-use-of-hard-start-kits-on-refrigerator-compressors-electrolux-policy/

 

Is it all in the eye of the believer?  Maybe so.  As our Lord Himself told the father of the demon-possessed boy, "If thou canst believe, all things are possible to him that believeth." [Mark 9:23]

Customer told me the refrigerator worked fine for 2 to 3 weeks and then died. I am not going to cause him more undo expense. I will advice him to get a new fridge or a good used one. I also believe "you reap what you sow"



Samurai, I agree with you completely.

I know the following passage talks about something else. But?  You do reap what you sow. Thanks to the whole Appliantology Academy. Love your neighbor as you love yourself.

 

As Malachi says:

 

“if I will not open for you the windows of heaven and pour out for you a blessing until it overflows.  Then I will rebuke the devourer for you, so that it will not destroy the fruits of the ground; nor will your vine in the field cast its grapes,” says the Lord of hosts.

 

Listen to this: Psalm 8

If  the compressor will not start on OEM start pak and your Meg-O-Meter sez the windings are in the green ( off the scale ) it is more a mechanical problem........  I would have used an Supco 3-N-1   model number RCO 810, good for 1/12 to 1/5 H.P. compressor...........An RCO 410 is good for 1/4 to 1/3 H.P...too much uummppphhhh to get it going.........But, as in the previous posts that we have discussed this, it is like Pepsi or Coke......Rum or vodka......  When I install a 3-n-1, I tell the customer it is on "life support", this will get you thru to keep the beer cold till you get another refer.....I  have units going on a year with the smaller H.P. 3-N-1................Out here in this neck of the woods, they get a new unit and the one on life support becomes the garage cooler, A.K.A  the  Beer-N- Bait  unit......
