A GFCI has circuitry that will trip if it detects that the load-side neutral is grounded, regardless of current flow.
Also, many refrigerators, bathroom exhaust fans, and fluorescent lights will trip GFCIs because of their inherent leakage current and are therefore not recommended to be GFCI protected.

The best solution is to use a generator without a GFCI and back-feed your panel box through a branch breaker that is interlocked with the main.

Because they may be able to give you more insight on what the problem may be.

You shouldn't have to disconnect the ground at the furnace. That is why I am suggesting that you contact the gen mfg. I'm not there and can only speculate what the problem may be.

In every house I have seen, the neutral is bonded to the ground at the panel box. If you connect a GFCI-equipped power source (eg: generator) to a circuit with a bonded neutral you will trip the breaker because it is designed to trip under those conditions. That means that you cannot connect such a generator to the panel box. You also cannot connect it to anything that may have a connection between the neutral and the ground that will allow more than 5mA of current, which at 120VAC means approximately 24,000 ohms of resistance. A lot of appliances and fixtures can experience that amount of leakage current, and refrigerators are among them.

Disconnecting grounds is not a good idea under any circumstances, and you can still get a pretty good shock from a GFCI protected circuit under some conditions, particularly if you have created a floating neutral by removing the ground.
