My haier fridge will come on for a few seconds and then trip itself off. is there something wrong with compressor

When power goes on and off suddenly, it can cause the compressor to overload and "trip out" This is supposed to protect the compressor from being electrically damaged. In most cases, after 10 or 15 minutes, the compressor will reset. It is usually safer to switch off the fridge or unplug it for 10 to 15 minutes to ensure a full reset. If it doesn't start, the power surge may have damaged the compressor relay. or overload device on the side of the compressor. I would doubt that it damaged the compressor itself. Be aware of the relay and overload device, unfortunately, there are Techs who will quote for a compressor job when all it needs is a relay or overload.

Hmm, I'm no expert but since I don't see any other solutions I will give you my meager opinion. 1. In foresight you can't disconnect a compressor while it's running and reconnect it repeatedly or you will fry the compressor, especially in bigger units. A period of 15 minutes should be given to let the gasses convert back or the compressor works overtime. Same reasoning when moving a fridge to not lay it down but if necessary allow the fridge to remain upright for a while prior to operating. For the temperature relay, it is a black on one side, and aluminum on other, 4x a nickel - sized coin shaped looking thing that is a safety feature and it is on the compressor for overheating shut off. This typically wouldn't allow you to hear anything once burnt or shorted so the compressor wouldn't work at all. Therefore I suspect the Capacitor or compressor in this case and be careful to short it out with a plastic handle screwdriver once unit is unplugged as all capacitors retain power and will give u a jolt if not more serious :(_ I would seek a used capacitor from a junk fridge these are typically located under a black cover on the compressor as well and look like a small soup can. Take pics of the wiring for reconnecting and be sure not to contact the ends of the capacitor until you shorted it out as described above. Capacitors can be tested with an ohm meter but is not an accurate test. Try to get the right measuring capacitor for replacement and the amount of farads next to the voltage on side of capacitor is more important than a voltage as long as voltage isn't lower than the original. Also a capacitor is polarity sensitive so don't mix that up. Not sure if I answered your question but may have given you ways to solve them.

sounds like the compressor can't start. could be the compressor itself, or the capacitor that kicks it on

I would say that the motor is humming because it is not turning and the click is when the overload control switches the power off. It may be a start run capacitor blown out but it may be a seized compressor motor. have a fridge mechanic check it out.

The click you heard is the thermal overload. This snaps open when the compressor is too hot.
Unplug the unit for 24 hours and don't move it.
Then plug it in and see if it comes back on temp.

some thing is wrong

If the compressor starts and runs for a few seconds it could be the relay. Or it could be the compressor itself has failed. When a compressor starts and runs for a short period it is possible that the relay contacts are arced together which would have both the start and run winding in the motor engaged at the same time for more than 3 seconds. This would result in the compressor tripping out on the thermal overload. It depends on what type of relay your compressor has. If it is a thermal relay, unplugging the refrigerator for about 15 minutes would allow the relay to cool off and reset.

what is elcb

The click your hearing is a thermal cutout that is kinda like a little breaker, it gets to the temp that it is designed for and trips. If its making a high pitch noise, more than likely the compressor itself has gone out and needs to be replaced, its getting a high load and triping the thermal cutout.
