Dryer Not Heating Properly? Thermostat WP3387137 – Fix Heat Cycling Issues Fast

A failed cycling thermostat is one of the most common reasons a dryer runs but produces no heat — or overheats and shuts off mid-cycle. In most Whirlpool-platform dryers, the cycling thermostat regulates the drum temperature by cycling the heating element on and off. When it fails, the dryer either runs cold, overheats and trips the thermal fuse, or shuts off before clothes are dry. ⚡ Common failure point in Whirlpool, Maytag, Kenmore, and KitchenAid dryers built on the same platform. Part WP3387137 is the genuine OEM replacement that restores accurate temperature cycling and protects your thermal fuse from repeat failures.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dryer powers on and drum turns normally
• ✔ Timer and controls respond correctly
• ✔ Thermal fuse has been tested and is not blown (or has already been replaced)
• ✔ ONLY problem is no heat, insufficient heat, or dryer shutting off before cycle completes

🔧 Common Symptoms

• Dryer runs but produces no heat
• Clothes still damp after a full cycle
• Dryer overheats and shuts off mid-cycle
• Thermal fuse blows repeatedly after replacement
• Dryer takes multiple cycles to dry a normal load

✔ If these symptoms match, the cycling thermostat is the most likely failed component in the heat circuit.

✔ In most cases, replacing this thermostat restores normal drying performance immediately.
