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.

Can you hook up a two pole 20 amp breaker to a 30 amp outlet for a dryer?
No, that is not safe or appropriate. The breaker and outlet must be the same amperage to protect the electrical circuit and appliance. Using a 20 amp breaker with a 30 amp outlet could cause damage to the appliance, create a fire hazard, and violate electrical codes.
I have a 15 amp tool hooked up to a 15 amp breaker- This trips the breaker even with nothing else running- There is also a GFCI outlet on the same circuit- Is the breaker or GFCI bad?
It is likely that the 15 amp tool is drawing more current than the breaker can handle, causing it to trip. The GFCI outlet might not be the issue here unless there is a ground fault causing it to trip. Consider using the tool on a circuit with a higher amperage breaker to prevent tripping.
What cause circuit breaker to trip when refrigerator plug in?
The circuit breaker may trip when the refrigerator is plugged in due to a power surge caused by the refrigerator's compressor turning on. This sudden spike in electrical demand can trip the breaker as a safety measure to protect the electrical system from damage. It could also be due to electrical overload if the circuit is already carrying a heavy load from other appliances.
Plugging an electric heater into a GFI outlet caused the lights and other outlets to go out but didn't trip the circuit breaker why?
It's possible that the GFI outlet was overloaded by the electric heater, causing it to shut off power to prevent a potential hazard. The circuit breaker may not have tripped because it was on a different circuit from the GFI outlet. It's important to have a licensed electrician inspect the outlet and wiring to ensure safety.
Does breaker trip when circuit it is protectiong got wet?
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.
