XPARTCO 279393 Dryer Terminal Block Screw Kit
The XPARTCO 279393 is an aftermarket replacement terminal block screw kit compatible with a wide range of Whirlpool-family electric dryers including Whirlpool, Kenmore, Maytag, KitchenAid, Amana, Roper, Admiral, Estate, Crosley, Inglis, Magic Chef, and Norge. The terminal block screws secure the dryer power cord wires to the terminal block — the connection point where 240V power enters the dryer. Loose, corroded, or damaged screws at this connection can cause intermittent power loss, blown fuses, tripped breakers, or dangerous arcing.
This kit includes 3 chrome-plated screws and 3 nuts — everything needed to restore a secure, conductive connection at the terminal block. The chrome plating improves electrical conductivity and corrosion resistance. Screws measure 7/16" L x 7/16" W x 11/16" H; nuts measure 1/2" L x 1/2" W x 1/8" H. Installs in under 15 minutes with basic hand tools.

⚠️ Electrical Safety Warning This kit connects the power cord to the dryer's terminal block — a high-voltage connection carrying 240V. Always unplug the dryer and shut off the circuit breaker before beginning installation. Loose or improperly tightened terminal screws can cause arcing, overheating, blown fuses, or fire. If you are not comfortable working with high-voltage electrical connections, have this part installed by a qualified appliance technician.
Installation Notes
⚠️ Unplug and Switch Off Breaker Before Starting Unplug the dryer from the wall outlet and turn off the circuit breaker for the dryer before beginning any work on the terminal block. Locate the terminal block cover plate on the back of the dryer and remove it by unscrewing the retaining screw. Use needle-nose pliers to carefully disconnect the power cord wires from the terminal block. Remove the old screws and nuts using a Phillips or flat-head screwdriver. Install the new 279393 screws and nuts into the terminal block. Reconnect the power cord wires to the correct terminals — refer to the label inside the terminal block cover or your dryer's wiring diagram to confirm wire positions. Tighten all screws firmly but do not overtighten. Replace the terminal block cover plate. Restore power and run a test cycle to verify correct operation. Tip: While the cover is off, inspect the terminal block itself (part 694431) for burn marks or damage. If the block is damaged, replace it before reinstalling. Tools needed: Phillips screwdriver, flat-head screwdriver, needle-nose pliers.
Frequently Asked Questions
What is the terminal block screw kit used for?
The terminal block screw kit secures the three wires of the dryer's power cord (two hots and a neutral, or two hots and a ground depending on cord type) to the terminal block at the back of the dryer. This is the point where 240V power enters the machine. The screws must be firmly tightened to maintain a safe, low-resistance electrical connection. If they loosen or corrode over time, resistance increases at the connection — causing heat, arcing, blown fuses, or power loss.
Can I also use this kit when installing a new dryer power cord?
Yes — this kit is commonly needed when installing a new 3-wire or 4-wire dryer power cord. When switching from a 3-wire to 4-wire cord (or vice versa), the terminal block screws and nuts often need to be loosened and retightened, and replacing them with a fresh set ensures a secure, corrosion-free connection from the start.
Should I also inspect the terminal block itself?
Yes. While the terminal block cover is off, inspect the block itself (part 694431) for burn marks, melted plastic, or damaged terminals. If the block shows any of these signs, it should be replaced before reinstalling — new screws alone cannot fix a damaged terminal block. Contact our support team to find the correct terminal block for your model.
Does this kit work for gas dryers?
No. Gas dryers use a standard 120V three-prong household plug and do not have a terminal block for power cord connections. The 279393 kit is for electric dryers only, which use a 240V outlet and require a hard-wired terminal block connection for the power cord.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is made from chrome-plated metal to match the dimensions and electrical performance of the original 279393 screw kit.
