Roper Dryer: not heating and timer not advancing
What is this symptom?
If your Roper dryer tumbles but fails to produce heat and the timer doesn't advance, it can lead to uncompleted drying cycles. This issue may cause the dryer to run indefinitely until you manually stop it, leaving your laundry damp and unmanageable. Understanding the potential causes is essential for effective troubleshooting.
Important Tips for Roper Models
- Roper dryers commonly fail thermal fuses, cycling thermostats, heating elements, and gas burner components causing no heat and can impact timer advancement.
Possible Causes
Thermal fuse blown or open thermostat circuit
How to Identify: Dryer runs but has no heat, and thermal safety devices have no continuity when tested with a multimeter
Part: Thermal fuse / thermal cutoff / thermostat
Faulty cycling thermostat linked to timer advance
How to Identify: Multimeter testing shows no continuity; symptoms include no heat and timer not advancing automatically through cycles
Part: Cycling thermostat
Heating element (electric) or gas burner components (gas models) failure
How to Identify: Heating element doesn’t glow (electric or gas igniter glows but no flame (gas, dryer produces no heat though drum spins
Part: Heating element (electric) or igniter/gas valve solenoid/flame sensor (gas)
Faulty timer motor or internal timer contacts
How to Identify: Timer dial doesn’t move during cycle even if motor runs; multimeter shows open circuit in timer motor or contacts
Part: Timer motor / internal timer contacts
Control board or wiring fault affecting heating circuit and timer drive
How to Identify: No obvious faults in thermostat, heating element, or timer, yet dryer still won’t heat and timer won’t advance; visible board damage or wiring issues
Part: Control board / wiring harness
DIY Solutions
Test and replace thermal fuse/thermostat
- Unplug dryer and shut off gas if applicable
- Access the thermal fuse and thermostats (often near blower housing/heat source)
- Use a multimeter to test continuity; replace any open devices
Test and clean venting and lint traps
- Unplug dryer
- Remove and clean lint filter
- Inspect and clear exterior and interior vent paths of lint/obstructions
Test cycling thermostat and timer motor continuity
- Unplug dryer
- Access and locate cycling thermostat and timer motor
- Use multimeter to test for continuity; replace any defective parts
Inspect and replace heating element or gas burner components
- Unplug dryer and turn off gas
- Access heating element (electric) or igniter/solenoids (gas)
- Test and replace failed parts
Next step
Choose the next step for not heating and timer not advancing
Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.
Most relevant component to inspect
Thermal Fuse
A safety device that cuts off power to the appliance if it starts to overheat.
- Typical part-only price
- $10 - $20
- DIY difficulty
- Easy
- Estimated time
- 10-20 mins
Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Thermostat
Regulates temperature by turning the heating or cooling system on or off.
Heating Element
Heats the water or air inside the appliance to the required temperature.
Flame Sensor
Confirms burner flame or radiant heat so the appliance can control gas flow safely.
