When your dryer tumbles normally but doesn’t produce any heat, it usually means **a heating component has failed** — or airflow is blocked. The good news is: many checks can be done **safely at home** before calling a technician.
⚠ Is It Safe to Run a Dryer With No Heat?
Yes, usually — but only temporarily. A dryer that runs but doesn’t heat may still circulate air, which means **clothes won’t dry properly** and may develop odors. However, if there is a **burning smell or loud noises**, stop using it immediately.
🔍 Most Common Causes (Ranked by Likelihood)
- Blown thermal fuse (very common)
- Failed heating element
- Blocked exhaust vent
- Thermostat failure
- Loose or burnt wiring (rare)
🧰 Quick Checks You Can Do Safely
- Check the lint trap and clean it fully.
- Test another heat setting (e.g., turn to “High” or “Timed Dry”).
- Make sure the exhaust hose is not kinked or blocked.
- Restart the dryer after unplugging it for 5 minutes.
🧪 How to Test the Fuse or Heating Element
To test components correctly, you usually need a **multimeter**. Many appliance stores offer simple fuse/heating element test kits.
| Part | Cost (Canada) | Difficulty |
|---|---|---|
| Thermal fuse | $15–$30 | Easy |
| Heating element | $60–$120 | Medium |
| Multimeter | $20–$50 | Easy |
Tip: If the fuse blows more than once, it usually means **another issue is causing overheating**, such as restricted airflow.
🛠 So… When Should You Call a Technician?
Call a technician if any of the following are true:
- The dryer shuts off randomly
- There is a burning smell or visible smoke
- You see damaged wires or melted plastic
- You tested parts but still no heat
