Kenmore Dryer Error Code Service Cord

The Service Cord alert means the dryer has detected that the 240-volt power supply cord is not correctly wired to the terminal block on the back of the dryer. This is a wiring configuration error, not a mechanical failure. It most commonly occurs during initial installation or after a cord has been replaced. The dryer must be unplugged before inspecting or correcting the wiring.

Yes, an incorrectly wired service cord is a serious safety concern. A miswired 240-volt connection can create shock hazards, cause damage to the dryer's control electronics, or in severe cases present a fire risk. Do not attempt to operate the dryer until the wiring has been inspected and corrected. If you are not comfortable working with high-voltage wiring, contact a qualified appliance technician or electrician.

If the existing cord just needs to be rewired correctly at the terminal block, there is no parts cost and the repair can be a straightforward DIY task. If the cord itself needs to be replaced, a new 3-wire or 4-wire dryer service cord typically costs between $15 and $40 depending on gauge and length. If a technician is hired to perform the inspection and rewiring, expect a service call fee in the range of $75 to $150.

Start by unplugging the dryer from the wall outlet. Remove the terminal block cover on the rear of the dryer and compare the existing wiring to the diagram provided in the installation instructions for your specific cord type, either 3-wire or 4-wire. Correct any improperly placed wires, verify the ground strap is configured correctly for your cord type, and ensure all connections are tight before restoring power.

Simply resetting or power cycling the dryer will not clear this error because the underlying wiring problem remains. The alert will return each time the dryer is powered on until the service cord is correctly installed at the terminal block. The error requires a physical correction of the wiring, not a software or control reset.
