Water-condensing and heat-pump combinations can use different systems and owner-care routines. Knowing the type helps the team establish whether the work falls within its service scope.
Understanding this situation
Do not guess from energy use or a warm cabinet. The model reference and manufacturer's specifications are better starting points. A general claim that the dryer is not hot is insufficient to identify how the appliance should behave.
A useful next step
Provide the full identifier and describe the drying result. Mention any filters or warnings shown in the manual. Sealed refrigerant-circuit work is outside this service, so suitability should be established before assuming every heat-pump fault can be accepted.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
