Do not run a vented dryer contrary to its required exhaust arrangement. Disconnecting the hose changes where heat and moisture go and is not an appropriate customer diagnostic trial.
Understanding this situation
A dryer that seems faster in that state has not been proved safe or repaired. The restriction or installation concern still needs to be identified through suitable assessment.
A useful next step
Stop use and arrange correction according to the model's installation instructions. Describe any recent hose or outlet change. Do not leave the appliance exhausting into cabinetry or the room simply to complete an urgent load.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
