Re: My Frigidaire #LSR7333PQ has had two compressor...
Compressors fail due to:
bad start relay.
bad fan motor.
to name a few problems.
You should be under a 5 year seealed system prts and labor warranty.

thata a close call, if you indeed know that the compressor is running.. should be hot when on..and still no cool in freezer section. sounds like a MAJOR refrigeration issue, requiring sealed system repair.. its close because the manufacturer covers selaed system repairs for 5 yrs. ck your manual and with the manufacture first, because you can replace the unit for cheaper than doing repair out of warrantee,
Good question. TO give you an idea Id have to know what kind of failures they were. 1 Grounded, shorted, or open windings indicate an electrical problem. This could be caused by external components or power fluctuations. Or a manufacturer defect in the motor. 2 Stuck or not pumping indicate mechanical problems with what could be the compressor its self (again a manufacturer defect) or non defrosting trouble or contaminated refrigerant oil residue from the first compressor.
To me replacing the drier on any compressor and on most all refrigerant related problems is a requirement. This helps eliminate the contamination in most cases. If you purchased a compressor the drier should also be replaced on domestic refrigerators its usually a copper colored piece 4" to 8" long about 1" dia and same size tubes on both ends close to the 1" area. If your not getting this part replaced each time I feel like your not getting quality work done with comon refrigeration practices. And could lead to such a problem.
Back about 15 years ago one of the big appliance manufacturers were making their sealed compressor parts from composite materials that would not hold up in all environments of use. Compressor failures were rampant. I cant say this is the reason but I can say it cant be either.
Possible main pcb failure failure which would cause everything to cut out and restart . Is the compressor or back of the appliance hot ?? Do all the control lights go out when the compressor cuts out ??
its really just up to you. I am a service tech in grants pass oregon and i know compressors dont last anymore. Its because in the last 10 years they have switched from r12 freon to 134a. 134a has higher head pressures which make the compressor go out. If the compressor warranty isnt too much money i would do that warranty. You dont really need the others.
there could be a partial restriction in the capiliary line causing higher that normal high side pressure in the system when the compressor is running
have the tech to replace the suction line along with the compressor let them know that this is the third one gone bad
It will rattle slightly, this is normal. The ones that are burned out will sound like they have gravel in them, you can defininely tell something is wrong.
The problem with diagnosing Kenmore fridges with this problem is that there are different manufacturers. Yours is built by Frigidaire and probably has a Tecumseh compressor. We find more failed compressors with the Tecumsehs than we do with the models that have Embraco compressors. The models with Embraco's generally have more relay failures.
You should not hear the buzz/hum at startup. You will need to replace the compressor, which will be replaced at no charge to you if it is less than 5 yrs old.
If it is older than 5 yrs, you can have it replaced, but it will be almost as expensive as a new fridge. You can buy an aftermarket start device called a 3-in-1. This has a start capacitor built in to give it a little more boost on start up. I don't recommend using them unless it is a short term fix until the compressor can be replaced or if it is out of warranty and there is nothing to lose anyway.
