Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.

1) How many house wires and the wire colors on the original dryer receptacle?

2) Was the original dryer receptacle a NEMA rated 10-30R?

Customer: replied 2 months ago.
3 new cord has 4
Expert:  Kevin replied 2 months ago.

Since the original wall receptacle was a 3 prong, you need to retain the 3 prong receptacle and use a 3 prong cord. See attached diagram.

It is a code violation to use a 4 prong cord where you only have 3 house wires.

3
Expert:  Kevin replied 2 months ago.

Not sure what you mean by 3?

Customer: replied 2 months ago.
that's the way ive got it hooked up
Expert:  Kevin replied 2 months ago.

1) Is the breaker a 30 amp double pole and the house wires are 10 AWG copper?

2) You mention that you are using a 4 prong cord, correct? If so, you need to use a 3 prong cord....ie... just like the diagram shows.

Customer: replied 2 months ago.
my breaker is a single pole and never had issue before
Expert:  Kevin replied 2 months ago.

An electric dryer requires a double pole 30 amp breaker and not a single pole. Electric dryers are 240 volts and not 120 volts. Thus the reason for a double pole breaker.

sounds like I need new breaker 1st
Expert:  Kevin replied 2 months ago.

1) If the original dryer was an electric version, you should already have a 30 amp double pole breaker installed in the panel
