This is a 4 wire system and the first thing I thought of was to separate the neutral from ground in the dryer. So we took the ground off the neytral and used a lug to bond the the dryer. Still wouldnt hold. The same problem on a slide in range?
GFCI protection for stoves??

Electricians that have always let the appliance dealers install the cords will now need to learn how. IDR ever having a 4 wire one done correctly.
You still have a N to G connection in the appliance. I would 1) take a good look at the wiring diagram of the appliance; and 2) measure the resistance of the appliance N - G terminals.

Take an ohmmeter and test neutral to ground and see if something isn't amiss. I assume you know to connect the neutral of the gfci breaker to the neutral bus and the neutral from the appliance circuit to the gfci breaker.
I don't mean to demean your knowledge but we don't know what you know

Yes sir We have been doing for quite a while. You see the delima is the inspectors dont seem to care about the capability of the breaker with appliances. We went through the AFI and the Samsung refrigerator issues while back. We seem to be held in the middle because we bide by the codes but the manufacturers have no responsibilities to make their product work. We wire per code and use products that are top quality in the trade.

New ranges should have no problem as long as they are properly connected for 4 wire. Open the range up and look at the connections or use the continuity check as suggested.

Old ranges may actually have a problem that needs repair. Or time for a new range.
No these are new out of the box THX

And IIRC a patented product doesn't actually have to work.
Supply and demand reigns supreme.

All the same brand?
You are putting the pigtails on?
If that wasn't the case, the electronics of the breaker wouldn't be in play, and, the breaker wouldn't immediately trip when the appliance was plugged in.

Based on don's comment, it may help to power the range from a non GFCI circuit long enough to "heat soak" all elements. But that would not necessarily explain tripping when it is first plugged in, without turning any elements on.

That’s my first choice as well.

Yes, if it is tripping right away, especially before you turn any of the heating elements on, there is a fault in the appliance.

Meter should tell you, but you can also isolate the ungrounded leads, if it still trips as soon as plugged in, has to be a neutral to ground fault.
If the branch circuit neutral was landed on the neutral bar instead of the breaker, how would the breaker ever sense a difference in the return and trip ?
