Types of Dryer Plugs: How to Replace Your Dryer Cord

Your dryer is one of the most hard-working appliances in your home, but it can experience wear and tear after handling so many loads of laundry. If this is the case with your dryer, you may have noticed that your dryer plug needs to be replaced. However, depending on the kind of dryer you have – gas or electric – you may require a different plug because their electrical circuits and dryer outlet types vary. Gas dryers require a 120-volt electrical circuit and use a grounded 3-prong outlet. Electric dryers, on the other hand, need a 240-volt, 30-amp circuit and a grounded, 4-prong power cord.

Additionally, if you’re installing a new dryer in an older home, or an old dryer in a new home, you may need to change your dryer cord. No matter your electrical needs, Maytag® Dryer Power Cords have you covered to maximize the power of your appliance and meet electrical regulations. Learn how to replace your dryer power cord below, whether you are moving or fixing a dryer that doesn’t heat anymore.

3-Prong vs. 4-Prong Dryer Cords

There’s a reason why there are different clothes dryer plug types. In the early 1990s, electric dryers used a 3-prong cord for a 240-volt circuit. Since then, homes built after 1996 are required to have a 4-prong dryer plug with a 240-volt, 30-amp circuit to reduce the risk of shock. The grounded, 4-prong plugs can also keep your home up to code. If your house has 4-prong outlets and your appliance has a 3-prong dryer plug, adjustments will need to be made to meet the standard mandates for 4-prong power cords. 

If you have questions or concerns regarding the electrical connections for your dryer, refer to your owner’s manual and consult a licensed electrician for assistance.

How to Change Dryer Cords in 5 Steps 

To keep your home safe and meet the standard regulations for houses built or remodeled after 1996, a 4-wire electrical connection is required for your electric dryer. Luckily, switching your dryer’s electrical connection to a 4-prong plug can be tackled in about an hour with a few tools and this general overview of the process. A gas dryer may use a grounded 3-prong wiring connection.

Always refer to your dryer’s manual for specific instructions and electrical circuit requirements. Consider consulting a licensed electrician for questions or concerns.

Are Dryer Plug Adapters OK to Use?

Instead, refer to your owner’s manual for instructions to switch to a 4-wire electrical connection to meet standard regulations and safety requirements.
