Roper Dryer: not heating

Professional Repair Guide

What is this symptom?

If your Roper Dryer runs but produces little to no heat, resulting in damp clothes even after a full cycle, you may be facing common issues such as a blown thermal fuse, a faulty heating element, or gas valve solenoid failure. Understanding these causes can help you resolve the heating problem effectively.

Urgency: Medium

Important Tips for Roper Models

  • Roper dryers commonly fail thermal fuse and heating element; gas models also have valve solenoid and igniter issues.
  • Ensure correct part numbers for replacement components; venting blockages often accompany blown thermal fuses.

Possible Causes

Blown thermal fuse

How to Identify: Dryer runs but heater does not. Test fuse for continuity with multimeter; no continuity indicates blown fuse.

Part: Thermal fuse

Faulty heating element (electric models)

How to Identify: No heat and heating element does not glow; test for continuity with multimeter; no continuity means element broken.

Part: Heating element assembly

Gas valve solenoid failure (gas models)

How to Identify: Igniter glows but no flame; multimeter/continuity test shows solenoid defective.

Part: Gas valve solenoid

Igniter failure (gas models)

How to Identify: Igniter does not glow; continuity test fails; no flame in gas burner.

Part: Igniter

Blocked vent/poor airflow

How to Identify: Restricted airflow, longer dry times, overheating; lint buildup visible.

Part: Venting system (ducts, lint screen)

Faulty thermostat or cycling thermostat

How to Identify: Multimeter shows no continuity; incorrect temperature control.

Part: Thermostat(s)

Control board or timer malfunction

How to Identify: Dryer runs but heating relay doesn’t engage; visible board damage.

Part: Control board/timer

Test heating element (electric)

Moderate 30-90 minutes
Tools Needed: multimeter, screwdriver
  1. Unplug dryer and access the heating element assembly.
  2. Disconnect element and test for continuity.
  3. Replace element if no continuity per model-specific instructions.
⚠️ Safety First: Ensure power is disconnected.

Test gas valve solenoids and igniter (gas models)

Advanced 60-120 minutes
Tools Needed: multimeter, screwdriver
  1. Disconnect power and gas supply.
  2. Access burner assembly.
  3. Test igniter and solenoids for continuity.
  4. Replace defective components with correct parts.
⚠️ Safety First: Turn off gas supply before servicing.
