Roper Dryer Motor Starts Then Stops: Troubleshooting... | appliancefaults.com

Technical Background:

The dryer's motor circuit typically includes a start switch, a motor relay (on the control board), a thermal fuse, and potentially a belt switch. When the start button is pressed, it provides power to energize the motor relay. Once the motor is running, the motor relay should maintain power to the motor, even after the start button is released. If any component in this circuit fails or opens, the motor will stop when the start button is released.

Symptoms:

The Roper dryer motor starts when the start button is held down, but the motor stops immediately when the button is released.

Possible Causes:

Faulty start switch
Open thermal fuse
Defective motor relay on the control board
Broken belt switch (if equipped)
Wiring harness issue between the start switch and motor

Solution:

1

Unplug the dryer from the 120V AC outlet and ensure the breaker is off.
2

Locate and test the start switch for continuity. Use a multimeter to check if the switch maintains continuity when pressed and released. Replace if faulty. Cost: $15-$
3

Tools: Multimeter, screwdriver.
4

Check the thermal fuse for continuity. It's typically located on the blower housing. A reading of 0 ohms (or close to it) indicates a good fuse. Replace if open. Cost: $10-$
5

Tools: Multimeter, screwdriver, 1/4-inch nut driver.
6

Inspect the dryer belt and belt switch (if present). Ensure the belt is intact and properly tensioned. Verify the belt switch is engaged when the belt is in place and closes the circuit. Replace belt if worn. Cost: $10-$
7

Tools: Screwdriver.
8

Access the control board and examine the motor relay. Look for signs of damage (burnt components). If unsure, consider replacing the control board. Cost: $80-$
9

Tools: Screwdriver, 1/4-inch nut driver.
10

Check the wiring harness between the start switch and the motor for any loose connections or damaged wires. Repair or replace as needed. Tools: Wire stripper, crimper, electrical tape.

Safety Warning:

Disconnect power before working on the dryer. Lockout/Tagout (LOTO) the breaker to prevent accidental energization. Capacitors can hold a charge; discharge them before handling the control board. Some internal components operate at 120V AC - exercise extreme caution.

Prevention:

Regularly clean the lint filter after each load. Inspect the dryer vent for obstructions at least twice a year to prevent overheating, which can damage the thermal fuse and other components.

Expert Tip:

Some Roper dryers have a diagnostic mode. Consult the service manual or search online for the specific sequence for your model to retrieve error codes that may pinpoint the faulty component. Typically this involves pressing a combination of buttons in a specific sequence within a short time frame.

Frequently Asked Questions

•How do I find the thermal fuse on my Roper dryer?

The thermal fuse is usually located on the blower housing, inside the rear panel of the dryer. It's a small, white, cylindrical component with two wires connected to it. You'll need to remove the rear panel to access it.

•How can I test the start switch with a multimeter?

Set your multimeter to the continuity setting. Disconnect the wires from the start switch. Place the multimeter probes on the switch terminals. Press the start button. The multimeter should show continuity (a reading of 0 ohms or a beep). Release the button; continuity should be broken (an open circuit). If it doesn't behave this way, replace the switch.

•Where can I find the service manual for my Roper dryer?

You can often find the service manual online by searching for the model number of your dryer followed by 'service manual'. Websites like AppliancePartsPros or RepairClinic may have them available for download. Sometimes the service manual is also located behind the access panel on your dryer.
