Brandt Partial Heat Pump Performance Loss

Heat pump dryer runs but air inside drum is only lukewarm and drying is very slow

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Dirty evaporator/condenser coils, Blocked airflow around heat pump module, Failing compressor, Faulty temperature sensor in heat pump circuit

Safety first: Unplug the dryer. Do not open the sealed refrigerant system.

Steps:

1. Clean all filters and heat exchangers: Ensure lint filter and any additional filters are clean. Vacuum dust from fixed heat pump coils carefully.
2. Ensure ventilation: Make sure there is adequate space around the dryer for air circulation.
3. Test with small load: Run a cycle with a small load and monitor temperature. If performance remains poor, a technician should check the compressor and sensors.
