Using a 3-prong range cord on a dryer is not recommended and can be unsafe. While both ranges and dryers typically use 240-volt circuits, they have different electrical requirements and plug configurations.

Older dryers were often manufactured with 3-prong cords, which included two hot wires and a neutral wire. However, modern electrical codes and safety standards require dryers to be equipped with 4-prong cords to include two hot wires, a neutral wire, and a separate grounding wire.

Here's why you should not use a 3-prong range cord on a dryer:

  1. Safety concerns: Dryers require a grounding wire for safety reasons. The grounding wire protects against electrical shocks and helps prevent the dryer's metal parts from becoming electrified in case of a malfunction.

  2. Compliance with electrical codes: Many local electrical codes now mandate the use of 4-prong dryer cords for new installations and replacements. Using a 3-prong cord may not meet current code requirements and could result in safety violations.

  3. Compatibility: The plug configurations for range cords and dryer cords are different. Attempting to fit a 3-prong range cord into a 4-prong dryer outlet (or vice versa) may require modifications that can be hazardous and damage the outlet or cord.

If your dryer currently has a 3-prong cord, it's advisable to upgrade it to a 4-prong dryer cord to comply with safety standards and electrical codes. 4-prong dryer cords are widely available, and the installation process is straightforward. However, if you're unsure or uncomfortable with the process, it's best to seek the assistance of a qualified electrician to ensure a safe and proper installation.
