Why does the dryer get stuck at 1 minute and fail to finish?
Detailed guide explaining why heat pump/condensation dryers pause on final minutes due to humidity sensors or lint filters.
Recommended steps:
-
1. Lint layer coating moisture sensor bars
Modern dryers use twin metal conductivity sensor bars below front door rim. Residue from fabric softeners creates an insulating film making sensors detect moisture continuously.
💡 Wipe both metal sensor bars inside door frame with a rag dipped in white cleaning vinegar.
-
2. Secondary heat exchanger / condenser filter blocked
Restricted airflow across bottom heat exchanger forces control board to extend dry timer to prevent overheating.
-
3. Water collection tank full or condensate pump clogged
Empty upper drawer water tank and check lower sump float microswitch for caught threads.
Frequently Asked Questions
Should I use liquid fabric softener when drying clothes?
It is recommended to avoid heavy liquid softeners as they coat moisture sensors and clog fine mesh filter pores.
