Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Dryer may not start if the cutoff is open in the applicable circuit.
• Dryer may stop heating or shut down after operating for a period of time.
• Repeated cutoff failure may be associated with restricted dryer venting or overheating elsewhere in the appliance.

Check Before Replacing

• Disconnect electrical power before inspection or testing.
• Inspect the cutoff and its terminals for visible damage, loose connections, or heat discoloration.
• With power disconnected and the component isolated as required by the appliance service procedure, check continuity with a multimeter; an open reading indicates the cutoff is not conducting, but does not by itself identify the cause of the overheat condition.
• Check and clean the dryer venting and exhaust path before replacing a failed cutoff.
• Verify the replacement cutoff matches WP3403607 and the appliance service documentation; do not bypass the safety device.
