A GFCI trips whenever it senses a grounding problem. Not grounding the outside surface of radios, fans, fridges, metal lamps and hand tools can put 120 volts on the device where you can touch it and possibly be killed.
The GFCI trips so you will not be killed. Best to have an electrician check out your fridge. If it is OK, then the GFCI may be At Fault.
In many cases motors will trip GFCIs. This is less of a problem with the increase in motor inefficiency but very often still with refrigerators. You need to replace your outlet, assuming it isn't a counter top outlet, with a normal one or, if it is piggie backed onto a GFCI up the line, remove it from that circuit.
As to your question of why, I only know that somehow, probably through the motor's capacitor, your refrigerator pulls more current on one wire just fractions of a second before the current returns on the other. This current imbalance is what trips a GFCI.

Can you use a GFCI plug into a GFCI outlet?
Yes you can. Lots of blow dryers have GFCI protection built in.
What happens if you trip a GFCI repeatedly on purpose?
Every time you trip the GFCI, the power to the device plugged into it will lose its supply voltage.
What happens when you plug a GFCI protected extension cord into an outlet that is GFCI protected?
When a GFCI-protected extension cord is plugged into an outlet that is also GFCI protected, it provides an additional layer of protection against electric shock. Both devices work in conjunction to quickly detect any imbalance in the electrical current and trip the circuit if necessary. This redundancy helps ensure increased safety against electrical hazards.
How many amps does gfci trip at?
GFCI receptacles are designed to trip at around 5 milliamps (0.005 amps) of current leakage to ground. When the GFCI detects this level of imbalance, it quickly shuts off the power to prevent electric shock.
How much amperage is needed to trip a 20amp GFCI outlet?
A 20 amp GFCI outlet will trip when the current exceeds 20 amps by a certain amount, typically around 5 mA to 6 mA, which is the typical trip threshold for GFCI outlets.
Will a GFCI outlet trip when the current is reduced or shut off?
A GFCI outlet will trip when it detects a ground fault, not when the current is simply reduced or shut off. The purpose of the GFCI outlet is to quickly shut off power when it senses a potential electrical hazard, such as a ground fault or leakage.
When would it be a better idea in a residence to install a GFCI breaker instead of an GFCI outlet?
GFCI Breakers are quite a bit more expensive than a GFCI outlet. More often than not a typical residence will need only a handful of GFCI outlets that combined together will be cheaper than a GFCI breaker. If you need to protect a series of outlets with GFCI protection you can simply connect the rest of the outlets on that same circuit downstream from the first outlet on the line and make that the GFCI. All you have to do is connect all the other outlets to the LOAD side of the GFCI outlet. If a GFCI fault occurs in any of the outlets down stream they will trip that very first GFCI plug you placed and keep you safe.
What is the trip time for a GFCI?
A GFCI (Ground Fault Circuit Interrupter) is designed to trip within milliseconds when it detects a fault, such as a ground fault or leakage current. This rapid response helps to protect against electric shock by quickly shutting off power.
Can you plug surge masters into gfci?
It is not recommended to plug surge protectors into a GFCI outlet because the surge protector can interfere with the GFCI's function. However, some surge protectors are designed to work with GFCI outlets, so it's best to check the manufacturer's instructions before doing so.
Can a difference of 5 milliamperes for 30 milliseconds trip a gfci?
Yes it can.
Why do you continue to trip your GFCI in the garage when you plug in your Christmas lights into the outside receptical?
You might be overloading the circuit. What else is drawing power on that circuit or phase? Are your lights really OK or is there a short somewhere?.
What is a GFCI plug?
Ground fault circuit interrupter. Turns off the the power to the outlet, when the there is a leakage in current. example when you stick your finger in the outlet and the current leaks threw your body
