Dryer loses power unpredictably — heating element or fan fails to engage due to loose or corroded terminal block screws creating a poor 240V connection.
Internal thermal fuses repeatedly blow or the household circuit breaker trips, caused by resistance buildup at stripped terminal screw connections.
Terminal connections become dangerously hot during operation — a direct symptom of loose screws failing to maintain full metal-to-metal contact on the power cord wires.
Visible arc flashes, sparks, scorch marks, or smoke around the rear access panel — indicating critically deteriorated terminal block screw contact requiring immediate replacement.
💡 Pro Tip: How to Know Your Terminal Block Screws Need Replacing
Your part is likely the culprit if you notice any of the following:
⚠️ Dryer has intermittent power — heater or fan elements fail to engage consistently
⚠️ Internal fuses repeatedly blow or household circuit breaker trips when dryer runs
⚠️ Terminal connections feel abnormally hot to the touch during or after operation
⚠️ Visible arc flashes, sparks, scorch marks, or smoke around the rear access panel area
🔍 Diagnosis tip: Before replacing, unplug the dryer and remove the rear terminal block cover plate using a 5/16-inch nut driver. Inspect each screw for stripping, corrosion, discoloration, or carbon scoring. Even minor pitting on a 240V connection point is enough to justify replacement — this is a $10 fix that prevents a $400 service call.
