Description

This service thermo switch is a temperature-sensitive cutoff designed to monitor and interrupt heat when a dryer's internal temperature gets too high, helping protect the appliance from overheating and related failures. What it does

• Acts as a temperature-activated switch that opens to stop heat when temperatures exceed safe limits.
• Helps prevent overheating that can cause poor drying performance or damage to internal components.
• Can restore normal operation when replaced if dryer faults point to a failed thermal cutoff/switch.
• Common symptom: dryer runs but fails to heat or exhibits intermittent heating.

What's included One service thermo switch. Install notes

• Disconnect power (and gas if applicable) before inspecting or replacing the part.
• Verify correct orientation and secure connection of the switch and wiring harnesses; do not force terminals.
• Inspect surrounding insulation and ducts for damage or lint build-up before reassembly.
