A Whirlpool dryer that suddenly stops producing heat can be a major inconvenience—especially when laundry day is in full swing. This problem is more common than you might think and is often due to a few key components wearing out or malfunctioning over time. In this blog, we’ll explore the most common causes behind a Whirlpool dryer not heating and how you can troubleshoot the issue. If you prefer expert help, Express Repair is always ready to assist!
Before diving into the mechanical components, it’s important to ensure your dryer is receiving proper power. Whirlpool electric dryers require a 240-volt outlet. If only one leg of power is active (120 volts), the dryer may run but won’t produce heat. Use a multimeter or consult an electrician to confirm the outlet is supplying the correct voltage.
The thermal fuse is a safety feature designed to prevent overheating. If it blows, the dryer may run but won’t heat. This is often caused by blocked airflow—typically from a clogged lint screen or vent. Replacing the fuse is simple, but remember to address the root cause to prevent it from blowing again.
The heating element is what generates the heat in electric dryers. Over time, it can burn out, especially with heavy use. If the heating element is defective, the dryer won’t warm up. This part can be tested for continuity using a multimeter and should be replaced if it shows no continuity.
The high-limit thermostat acts as a second layer of protection against overheating. If it becomes defective, it may shut off the heat prematurely or prevent it altogether. Like other components, it can be tested for continuity and replaced if necessary.
This thermostat regulates the air temperature inside the drum. A malfunctioning cycling thermostat may fail to cycle the heat properly, resulting in no heat at all. Diagnosis typically involves checking its resistance levels with a multimeter.
For dryers with mechanical timers or electronic control boards, a fault in these components can interfere with the heating cycle. If all other components are functional, the issue could lie within the control mechanism. These problems are best addressed by professional technicians due to their complexity.
If you own a Whirlpool gas dryer, additional components like the gas valve solenoids, igniter, and flame sensor should be checked. A defective igniter or failed solenoids can prevent the dryer from heating even if it seems to be operating normally otherwise.
