Re: upright freezer not cooling
No…the relay is used to switch between the start winding (with capacitor) and the run winding in the compressor. It is usually fitted directly to the compressor and may be either a coil type electromagnetic device, or more usually these days a PTC or solid state device.
If this fails then the compressor won’t run, it rapidly overheats it’s protection device with the large current draw you described. This will cool and reset after two or three minutes.
