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
