Dryer Not Heating? Basic Checks First

Rule out simple causes like blocked airflow or incorrect settings before calling for repair.

Before You Call: Simple Dryer Heat Checks

If your dryer is running but not producing heat, or taking much longer than usual to dry clothes, clogged airflow is often the culprit. Before assuming a complicated internal failure, perform these basic checks related to airflow, settings, and power.
Important: This guide focuses on safe, user-accessible checks only. It does not cover diagnosing or repairing internal components like heating elements, thermostats, or fuses, which require professional attention due to safety risks.

⚠️ SAFETY FIRST! READ BEFORE PROCEEDING! ⚠️

ALWAYS unplug the dryer from the wall outlet before cleaning the lint filter housing or checking vents where possible. If checking breakers, leave the dryer unplugged.
FIRE HAZARD: Lint buildup is a serious fire hazard. Regular cleaning is essential.
NEVER operate the dryer without the lint filter properly installed.
If checking the exterior vent requires climbing or reaching, prioritize your safety.
If you smell gas (for gas dryers) or burning, STOP immediately, leave the area, and call for professional help.
If you are unsure or uncomfortable performing any step, STOP and contact a qualified professional.

Step-by-Step Basic Checks for No Heat

  1. Clean Lint Filter Thoroughly

    This is the most common cause. Locate the lint filter (usually inside the door). Remove it. Peel off lint. For stubborn residue, wash gently with warm soapy water, rinse, and dry completely before reinstalling. Also, check the filter housing for lint (unplug dryer first) and vacuum carefully.

  2. Check Exterior Dryer Vent Cap

    Go outside where your dryer vents. Ensure the flaps on the vent cap open freely. Clear away lint, snow, leaves, or nests blocking airflow.

  3. Verify Dryer Settings

    Double-check you haven't selected an 'Air Fluff', 'Air Dry', or 'No Heat' setting. Ensure a heated cycle is chosen. Check if an 'Eco' mode with lower heat is active; try a standard setting.

  4. Check Circuit Breakers (Electric Dryers Use Two!)

    Electric dryers use a 240V circuit with two linked breakers. Locate them in your panel (often labeled 'Dryer'). If one or both are tripped (middle/Off), reset ONCE (fully Off, then On).

    Caution: If either breaker trips again immediately, do NOT reset. Call an electrician or appliance tech.

  5. Check Gas Supply Valve (Gas Dryers Only)

    If you have a gas dryer, ensure the gas supply valve behind the dryer is fully open. The handle should typically be parallel to the gas pipe. If you recently had gas work done, it might have been closed. If you smell gas, leave immediately and call your gas company or 911.

Dryer Still Not Heating? It's Time for a Pro

If you have thoroughly cleaned vents, checked settings, and confirmed power/gas supply, and your dryer *still* fails to heat, the problem is internal (heating element, thermal fuse, thermostat, igniter, coils, board, etc.).
Due to significant electrical and fire hazards (and gas risks), further diagnosis or repair should only be performed by a qualified appliance repair professional. Do NOT bypass safety devices.
