What the symptom can mean
A wetter incoming load can take longer to dry even when a dryer is functioning. A new persistent change with warnings or a poor finish may instead warrant assessment of suitable components.
Start with the load
State whether the clothes were wetter than usual after washing and spin. Give the fabric mix and selected dryness level. Comparing unlike loads can hide which part of the routine changed.
Describe the end
Record whether the dryer completed, extended the estimate or stopped with a warning. Give visible tank or filter indications from that occasion, keeping them separate from a guessed diagnosis.
