This article will walk you through the process of converting a 4-prong dryer cord to a 3-prong cord<\/strong>, explain the wiring differences, and provide a wiring diagram<\/strong>. We\u2019ll also cover the option of using a 4-prong to 3-prong adapter<\/strong>, and most importantly, highlight the safety risks<\/strong> involved.<\/p>\n \\n<\/p>\n \u26a0\ufe0f Safety Warning: Always disconnect the power before working. Dryers run on 240 volts, which can cause serious injury or death. If you\u2019re not confident in your skills, hire a licensed electrician.<\/strong><\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n \\n<\/p>\n Two hot wires (L1 and L2) providing 240V.<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n One neutral wire, which also acts as the ground.<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Less safe, since neutral and ground share the same connection.<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n \\n<\/p>\n Two hot wires (L1 and L2).<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n One neutral wire.<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n One separate ground wire.<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Safer, because the ground is independent.<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n\\n<\/p>\n \\n<\/p>\n Tools:<\/strong> Screwdriver, pliers, wire stripper, camera\/phone (to record wiring before removal).<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Materials:<\/strong> A new 3-prong dryer cord<\/strong>.<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Power Safety:<\/strong> Unplug the dryer or switch off the breaker.<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n\\n<\/p>\n \\n<\/p>\n Open the terminal block cover<\/strong><\/p>\n \\n\\n<\/p>\n On the back of the dryer, remove the access cover with a screwdriver.<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/li>\n \\n \\t<\/p>\n Remove the old 4-prong cord<\/strong><\/p>\n \\n\\n<\/p>\n You\u2019ll see four wires: red (L1), black (L2), white (neutral), green (ground).<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Take a picture for reference.<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Loosen the screws and remove the cord.<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/li>\n \\n \\t<\/p>\n Prepare the new 3-prong cord<\/strong><\/p>\n \\n\\n<\/p>\n The cord has three wires: red (L1), black (L2), white (neutral\/ground).<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/li>\n \\n \\t<\/p>\n Connect the wires<\/strong><\/p>\n \\n\\n<\/p>\n Red \u2192 L1 terminal<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Black \u2192 L2 terminal<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n White \u2192 Neutral terminal (center)<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Important:<\/strong> Inside the dryer there is usually a grounding strap<\/strong> or wire.
