Electric dryers are common in many households, and when they stop heating, it can throw a wrench in your laundry routine. Let’s explore the steps to diagnose heating issues in electric dryers, focusing on key components that often cause problems.

First, check the power supply and circuit breaker. A tripped breaker is a frequent culprit when a dryer won’t heat. Locate your home’s electrical panel and ensure the dryer’s circuit hasn’t tripped. If it has, reset it and test the dryer again. If the breaker trips repeatedly, it could indicate a more serious electrical issue that requires professional attention.

Next, let’s examine the thermal fuse and thermal cut-off. These safety devices prevent the dryer from overheating. When they fail, they cut power to the heating element. To test these components:

  1. Unplug the dryer and locate the thermal fuse (usually on the blower housing or exhaust duct).
  2. Use a multimeter to check for continuity. No continuity means the fuse has blown and needs replacement.
  3. Similarly, test the thermal cut-off switch, typically found near the heating element.

The heating element is the heart of your electric dryer’s heat production. A faulty heating element is a common reason for a dryer not heating. To inspect the heating element:

  • Disconnect the dryer from power and remove the back panel.
  • Locate the heating element, which usually looks like a coiled wire.
  • Check for any visible damage or breaks in the coil.
  • Use a multimeter to test for continuity across the terminals.

If the heating element lacks continuity, it needs to be replaced. This task might require some technical skills, so consider professional help if you’re not confident in your abilities.

Lastly, inspect the dryer’s thermostats and heat sensor. These components regulate the temperature inside the dryer. Faulty thermostats can cause the dryer to stop heating or overheat. To check these:

  1. Locate the thermostats – there are usually several in different areas of the dryer.
  2. Use a multimeter to test each for continuity at room temperature.
  3. If any thermostat fails the continuity test, it should be replaced.
