Heat pump dryers are popular in Adelaide homes for their energy efficiency and gentle drying performance. But when they run without heating, it can be frustrating—and a sign that something isn’t working correctly. Below, we’ll walk through common causes, DIY checks, and when to call a professional dryer repair service in Adelaide.
How a Heat Pump Dryer Works
Unlike conventional vented dryers, a heat pump dryer recycles hot air through a closed-loop system. It uses a heat pump and refrigerant to extract moisture from clothes while consuming less power. Because of this unique system, heat issues often relate to airflow, sensors, or the heat pump unit itself rather than simple heating elements.
Common Reasons a Heat Pump Dryer Runs But Doesn’t Heat
1. Blocked Lint Filter or Condenser
Restricted airflow is the number one cause of heating problems.
Fix: Clean the lint filter after every load. Rinse the condenser unit under running water if your model allows it.
2. Dirty Moisture Sensors
Residue from fabric softeners and detergents can coat the sensors, causing the dryer to stop heating prematurely.
Fix: Wipe sensor strips inside the drum with a mild soap.
3. Overloaded Dryer
Heat pump dryers are efficient but work best with smaller, lighter loads.
Fix: Dry half-loads or separate heavy towels from lighter clothing.
4. Clogged Airflow Path
Heat pump dryers often have secondary filters and ducts. If these clog, the dryer may run but circulate cool air.
Fix: Remove and clean all accessible filters. Check for dust build-up around the heat exchanger.
5. Faulty Thermostat or Sensors
If the control system misreads the temperature, it may cut heat entirely.
Fix: Requires testing with a multimeter and may need part replacement by a technician.
6. Refrigerant or Heat Pump Failure
If the sealed refrigerant system develops a leak or compressor fault, the dryer cannot heat.
Fix: Only a licensed professional can repair or recharge refrigerant in Adelaide.
DIY Troubleshooting Checklist
✅ Clean lint filter and condenser
✅ Wash moisture sensors
✅ Ensure proper load size
✅ Reset the dryer (turn off power for a few minutes)
✅ Check if error codes display on the control panel
If these don’t solve the issue, it’s time to call a dryer repair expert in Adelaide.
