Roper Dryer: not stopping during cooldown
What is this symptom?
Is your Roper dryer not stopping during the cooldown phase? This issue can cause your dryer to continue tumbling or heating even after the timer runs out. Common causes include a faulty control board, a malfunctioning door switch, or restricted airflow. Understanding these problems can help you troubleshoot effectively.
Important Tips for Roper Models
- No official Roper manufacturer-specific documentation found for this exact symptom; community repair sources list control board and airflow issues typically.
- Moisture sensor and door switch faults reported in general dryer troubleshooting communities applicable to Roper.
Possible Causes
Faulty control board / timer not advancing to off position
How to Identify: Cycle never ends, display or timer doesn’t advance to end or shutdown; no response to cycle completion
Part: Control board (main control) or timer motor
Faulty door switch
How to Identify: Dryer keeps running even when door is opened mid-cycle; safety switch doesn’t interrupt operation
Part: Door switch
Moisture sensor malfunction (if equipped)
How to Identify: Auto-dry cycles don’t detect dryness; cycling into extended operation repeatedly; sensor bars dirty or defective
Part: Moisture sensor bars/strips
Restricted airflow / clogged venting causing extended cycles
How to Identify: Drying time is excessively long, clothes still damp, airflow weak at vent exit
Part: Vent system / lint filter
