Whirlpool Dryer Thermostat (WP3387134)

The Whirlpool Dryer Thermostat monitors dryer temperature and opens or closes an internal electrical contact to help regulate heat. It works with the heating circuit and blower airflow to keep drum temperature within a set range and reduce overheating.

Failure can come from normal wear of the contact points, heat stress, lint buildup that traps heat, restricted venting that raises operating temperatures, or physical damage from repeated thermal cycling. When it fails, it may stick open and stop heat, or stick closed and allow the dryer to run too hot.

These symptoms can help you decide if this thermostat matches your dryer’s problem:

• Dryer runs but does not heat or heat is weak
• Clothes take much longer than normal to dry
• Dryer overheats or shuts off on a high-limit safety
• Burning smell or unusually hot cabinet or exhaust air
• Heat cycles are irregular, with long periods of no heat or constant heat
