how can i fix it?

check the evaporation tray on top of the motor,if one is fitted ,dependent on make/model it should be holding water that drains from both fridge and freezer compartments.it may have become detached or have a split,.it is possible there's water getting into the defrost timer.

damp in electrics causes tripping.without looking at it it is difficult to say what's happened.drying wet areas with a hairdryer might help ????
Worry is why is it wet?
