Customer Questions and Answers for Hi-Limit Thermostat by Whirlpool

4.89 (64)
By: Whirlpool
Part Number: OEM18027138
Manufacturer Part Number: WP3977767

The Hi-Limit Thermostat is an OEM part for Whirlpool dryers. It functions as a critical safety device that monitors and controls the temperature within the dryer, preventing it from overheating. When the dryer reaches a temperature that is too high, this thermostat will cut off the power to the heating element to mitigate the risk of fire.

Symptoms of a bad Hi-Limit Thermostat include:

  • Dryer not heating adequately or at all
  • Clothes taking longer than usual to dry
  • The dryer repeatedly shutting off during a cycle
  • Excessive heat emitted from the dryer even on lower settings

Causes of a bad Hi-Limit Thermostat can include a malfunction due to electrical issues, lint buildup causing restricted airflow and increased temperature, or failure of other components like the cycling thermostat that can cause the dryer to overheat.

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

Ryan for Model Number LEQ8858JQ0

My dryer had no heat so I replaced the heating element and the hi temp thermostat, which was burnt. Hooked it all back up but still no hea . It is an older model than the one in the repair video and only has 2 wires that hook up to the thermostat (one to one end of the thermostat and the other to the heating element) not 3 wires. Is this correct? I have looked every where for a wiring diagram or picture of how it should look, can you help me with that? Thank you

Answer

Hello Ryan, you'll want to make sure you have 240v at the terminal block. If present you'll want to verify you are getting 240v at the heating element. We've emailed you a wiring diagram so you can trace your voltage to see where you are losing it at. Thanks!
