I have a Frigidaire side by side refrigirator.
Model no. FRS23LH5DSP. The compressor has been shuting off and not restarting unless I unplug for at least an hour. When it restarts it takes right off. I have bought a hard start kit but I dont think that will help. When it wont start it is not drawing current. I checked the schematic. The defrost module shuts off the compressor when in defrost. It also shuts off the condensor fan on same circut.
When my compressor is off the condensor fan is still running.
That takes the defrost module out of the picture. I have found that if I set a fan in back of refrigerator the compressor doesnt shut off.
It must be overheating. I checked the ohms on compressor and it
was within limits. What I need to know is the thermal protection of the compressor in the sealed unit or is it part of the start circut. The sealed unit says thermal protected on it.

Ostart Orun
"If memory serves"^
Overload will be on the comon pin on the exterior of the compressor
If you have the proper hard start device it won't hurt to install it. Problem is i see people putting the wrong hard start on compressors all the time. Match the horse power and if there is a run capacitor make sure the hard start has provision for it. If you use the right hard start it will be better than the factory relay because it adds a start capacitor which can greatly reduce peak amp draw during start up. The proper run capacitor can make a diff of over one running amp. If you post your compressor model number someone can likely look up it's horsepower
You should have some kind of reading between the start and run pins on your old relay with it unpluged using your volt meter ohm setting if it's still good

I have vacuuned it down and charged with 5 ounces of 134a low press 3 lbs.I think that there is a thermal protector in the sealed unit. I
have been on several forums and they all say the overload protector and thermal protector are the same thing. Overload
means amps, thermal means heat. I took the fan away it overheated and the compresser shut off. no draw. I installed a
3 and one hard start kit for test. No start and no draw. I am waiting for it to cool off to see if it will start.
