are the iteriror lights on inside the fridge?
are any fans running? either inside the freezer or in the backby the compressor?
can hear what sounds like the motor or a fan running
then the compressor should be running too
if its not you could have a bad start relay or a bad compressor
do you have a meter?
to measure volts ac on the compressor itself?
did you say this tripped a breaker in your house?
your compressor most likely siezed
Does this need replacing
and youll need a new refrigerator
the cost will be very exspensive for repair
better to replace it
