Question 220v oven wire

I am replacing my 50amp oven, my new on is a 30amp, the wire for the old oven is 6 gage can I just change the breaker? Will it cause a problem running 30amp 220 on 6 gage wire?

Possibly. The smaller breaker may not accept the larger wire, and there may not be enough wires in the cable. Newer ranges require a neutral conductor + ground, the old likely did not.

There is nothing wrong with 6 gage wire on a 30 amp breaker. This is perfectly legal and safe.

A 30 amp breaker will accept 6 gage wire. Even if it didn't, you can always pigtail smaller wire to the larger wire to make the connections.

While four conductor wire is now required for NEW installations, you are allowed to use older existing three wire circuits for replacement ranges (and dryers, too).
