Have new electric dryer. Have properly installed a three prong dryer cord to match the 3 prong dryer outlet. The outlet is on a separate, double pole 30amp breaker that is new.

The dryer will power on, but when the cycle starts it will stop and start flashing error--and an separate, unrelated GFCI outlet will trip. The circuit is on its own 20 amp breaker. I'm perplexed!

One thought: the dryer outlet is a three prong plug, but appears to be a four wire wire: I see a white neutral and a copper ground, both connected in their proper place on the bus bars.

Any thoughts?

Thank you!!

Sounds like you have two circuits some cross connected.

If this is a new circuit install you must use the four wire connection.

Thank you. These are existing circuits, not new. I can't quite see how the two would be crossing--but yes, that appears to be the case.

What is the error the dryer is flashing?

 

[kiakman]

The dryer just flashes the cycle time actually, not an error. It turns on, the cycle begins and then within 2 seconds stops, the GFCI trip, and the cycle time flashes.

Make and model of the dryer?

 

[kiakman]

Found it... just had to dig deeper into the panel. Someone had wired the Neutral to the Ground bus bar.

No more tripping. Happy Dryer. Thanks everyone for the ideas.

That does not make sense, unless maybe the neutral was loose.
No matter what it should not have been tripping the other circuit.

It's working now. I guess that is the important part.
