Answer If it doesn't trip, then the logic sensor is bad and the whole thing needs to be replaced. A residential grade gfi is about five bucks and is relatively easy to replace. Turn the power off first.
This failure was common with older style GFCIs that could be surge damaged and then fail to protect human life. Newer designs will (should) not reset if a GFCI has been damaged.
Yes.
When the outlet gets wet, the water conducts a small amount of current from the hot side to ground; the GFI senses there is an imbalance between the amount of current and "trips".
If you can plug the fridge into another outlet and it comes on, then the issue is either a bad outlet connection or the circut breaker may be going out and needs replacement. Try the fridge on another outlet 1st. If it trips that one too then there is a short in your fridge.
Probably not. If the appliance has multiple heating levels then you might get away with it. In this scenario you would only be able to use 30 amps of the appliance's 40 amp capacity before the breaker would trip.
There is a short somewhere in the line. Start at the outlet end and what is plugged into it and work your way back. If it is a GFI breaker, they can be bad and trip as soon as any drain is put on them. I have had them trip as soon as a drill is plugged in without even turning on the drill.
A 15 amp breaker will trip at 15 amps at an ambient temperature of 104 degree F. If the ambient temperature is higher the breaker will trip before 15 amps and if the ambient temperature is lower the breaker will trip after 15 amps. I would suspect the circuit is overloaded. But, you can change the breaker and see what happens. Just swap it with another one.
the breaker goes to trip position
That tells me the problem is with the outdoor unit. Most likely a dead compressor or fan motor. Additionally, your indoor and outdoor units are not on the same breaker.
No, it will just trip the breaker as you have a dead short.

A GFCI receptacle can pass it's "protection" to other outlets wired from it. If the GFCI trips, all outlets wired from it will "trip" also. A GFCI tripping will not necessarily trip the circuit breaker in the service panel.
Electric motors and GFI's do not get along. the initial draw to get the compressor going is usually enough to trip the GFI. Turn the breaker off and switch the GFI for a regular outlet and you will solve your problem.
Not unless the leakage current gets higher that what the trip setting of the breaker is. In many underground conduit systems the feeder conductors are in water continuously due to leaks in the under ground conduit system.
No, it will draw more power then the outlet provides and trip the circuit breaker.
Yes a shunt trip breaker can be activated manually.
