How long after I unplug my fridge can I plug it back on

Wait 3-5 minutes.

What happens if your fridge triped the fusebox and after 3-4 hours you reach home and put it back on and it trips again and you wait about 30 sec and try it again and it trips again after 20 secs and again you checked around and after 1 min you try again and it trips again. Could this be the cause of not colding anymore. I think the first time the fridge tripped that it gone bad. What do you think and thanks again.
The vendor of the fridge is blaming me of putting it on too soon.

A little confusing, what is tripping?

Fuse?

Circuit breaker?

GFI receptacle?

GFI breaker?

A fridge that has been unplugged can be plugged back in within 3-5 minutes. After that it should run fine.

If something is tripping again, then there may be a problem with the unit.

If it is a GFI receptacle or circuit breaker tripping, then the unit may work fine on a non GFI circuit.

If a fridge has been off for about 4 to 6 hours because it trip from a GFI receptacle and you reset the receptacle and it works for about 20-30 seconds. I checked around for about 45 sec to 1 min and reset it again and did the same again. After this I replaced the GFI with a normal receptacle. The fridge stayed on this time but no coldness. The vendor said that I unplug and plug too many times and damaged the motor. One thing he mentioned that the gas did not get a chance to settle but it worked for 20 sec. Does that make a difference? I think that from the very first time that the GFI trip that the fridge broke down. What do you think.

I think you have a defective appliance, and that you are dealing with a crook. Hope you have what ever paperwork to get this repaired or replace under warranty, assuming this is new.
