Dryer Not Heating? Common Causes and Solutions

A dryer that won’t heat up can be frustrating and inconvenient, leaving you with damp clothes and wasted time. If your dryer is not heating properly, don’t rush to replace it — there are several common issues that could be causing the problem. Let’s explore the most frequent causes and what you can do to fix them.

Why Is My Dryer Not Getting Hot or Drying Properly?

If your dryer is running but not producing heat, there are a few basic things to check first:

• Check the power source – If you have an electric dryer, make sure it’s properly plugged in and that the circuit breaker hasn’t tripped. Gas dryers should be connected to a functioning gas supply.
• Clean the lint filter – A clogged lint filter can restrict airflow, preventing proper drying.
• Inspect the venting system – A blocked dryer vent can cause the dryer to overheat and shut off heating elements as a safety precaution.
• Confirm the settings – Double-check that you’re using the correct heat setting and that the “Air Fluff” or “No Heat” option isn’t accidentally selected.

If these quick fixes don’t work, there could be more complex issues at play.

Why Is My Dryer Not Heating?: The More Complex Answers

If basic troubleshooting doesn’t solve the issue, your dryer may have a mechanical failure that needs repair. Here are some common causes of a dryer that won’t heat:

• Blown Thermal Fuse – The thermal fuse protects your dryer from overheating. If it blows, the heating element won’t work. This happens when vents are clogged or airflow is restricted.
• Faulty Heating Element – In electric dryers, the heating element generates the heat needed to dry clothes. If it’s burned out, the dryer will run but won’t produce heat.
• Defective Gas Valve Coils – For gas dryers, faulty gas valve coils can prevent the burner from igniting, meaning no heat is produced.
• Broken Thermostat – The high-limit thermostat or cycling thermostat controls the dryer’s temperature. If it malfunctions, the dryer may not heat properly.
• Bad Timer or Control Board – Some dryers rely on a control board or timer to regulate heating cycles. A defective timer may prevent heat from turning on.
• Faulty Igniter (Gas Dryers Only) – The igniter lights the gas flame in a gas dryer. If it’s faulty, the dryer will tumble but won’t heat up.
