Why Is Whirlpool Duet Dryer Not Starting?


A Whirlpool Duet dryer may not start for several reasons.

First, check the power supply to ensure the dryer is plugged in and receiving electricity.

Next, examine the door latch to confirm it is securely closed, which is necessary for the dryer to operate.

The start switch and cycle settings should also be checked for proper function.

If these external checks are in order, internal issues may be the cause, such as a blown thermal fuse, a broken drive belt, or a faulty control board.

Each of these components should be inspected and, if necessary, repaired or replaced to get the dryer working again.

Power Supply Issues

A common reason a Whirlpool Duet dryer won't start is due to power supply problems. This could be due to tripped circuit breakers, blown fuses, or low voltage at the outlet. To address this, check that the dryer's electrical supply is working by ensuring the circuit breakers are not tripped and fuses are not blown. The outlet should also provide the correct voltage.

If the circuit breakers have tripped or fuses are blown, reset or replace them to restore power. Make sure the dryer is securely plugged in, the connections are tight, and the cords are not damaged. Avoid using extension cords, as they may not support the dryer's power needs.

A PF error code on the dryer indicates a power failure, possibly from a temporary outage. Reset the dryer by unplugging it for a few minutes, then plug it back in.

Also, check the thermal fuse, which prevents overheating. Replace the thermal fuse if it has blown and other power issues have been addressed.

Faulty Door Latch

A malfunctioning door latch can prevent a Whirlpool Duet dryer from starting its cycle. The door switch, a safety feature, must confirm the door is closed for the dryer to operate. If the latch is defective, the control board won't start the cycle, and the Sensing light may turn on.

To address this, inspect the door switch for damage. A lack of a clicking sound when closing the door suggests the switch isn't engaging. Additionally, a broken belt switch could cause similar issues by stopping the dryer if the drum belt is broken.

Examine the control board for burn marks or damage, which could indicate an electrical problem affecting the door switch. The door switch mechanism should be intact, especially in models like the Duet Sport Dryer.

If the door switch is faulty, replacing it is typically a simple fix that allows the dryer to start and run safely.

Malfunctioning Start Switch

A faulty start switch may prevent a Whirlpool Duet dryer from starting its drying cycle. If pressing the start button does not activate the cycle, the switch may be malfunctioning. It is important to check that the switch is intact and sending signals to the control board. This can be done using a multimeter to test for continuity. If the switch lacks continuity, it needs replacing.

The belt switch should also be checked as it can stop the dryer from starting if the belt is broken.

If the start switch is defective, it is recommended to hire a qualified technician to replace it to ensure the dryer operates correctly. This can avoid further issues with the appliance.

Incorrect Cycle Selection

Selecting the wrong cycle can prevent a Whirlpool Duet dryer from starting. One common issue to check when a duet dryer won't start is if the cycle chosen is incorrect. A wrong cycle choice can cause the dryer not to operate.

To start the dryer correctly, make sure the chosen cycle fits the laundry load. Users may accidentally select a cycle that does not suit the fabric type, leading to a non-start. The Whirlpool Dryer offers various cycles for different drying requirements, such as heavy-duty or delicate cycles.

To fix this, users should confirm that the cycle settings align with their laundry's needs and that no additional options have been selected that could change the cycle's function. If the cycle is set correctly and the dryer still won't start, further investigation into power supply, door latch, or control board issues may be necessary.

In short, when a Whirlpool Duet dryer won't start, checking for the correct cycle selection is a vital step in troubleshooting.

Blown Thermal Fuse

A non-functional Whirlpool Duet dryer often indicates a blown thermal fuse. To confirm, test the fuse for continuity. This safety device stops the dryer from overheating by cutting power. If a technician finds no continuity with a multimeter, the fuse is blown and needs replacement.

During repair, it's crucial to also clear any blockages in the venting system. This prevents future overheat and extends the life of the new fuse.

Hence, fixing a blown thermal fuse and maintaining a clean vent system are essential for the dryer's operation and safety.

Worn Drive Belt

A worn drive belt often causes a Whirlpool Duet dryer not to start, as it can prevent the drum from turning. Over time, the belt may deteriorate, losing its ability to work with the drive motor and spin the drum. If the belt is damaged or broken, it will not grip the drum, stopping the dryer from starting.

Inspect the drive belt for signs of wear, such as fraying or thinning. A completely broken belt will leave the drum immobile. A worn belt can also activate the broken belt switch, a safety device designed to stop the dryer from starting to prevent damage or hazards.

To check the broken belt switch's functionality, use a multimeter for a continuity test. If the switch is defective, it may need to be replaced with part number AP3094230. If the worn belt has put extra strain on the drive motor (part number AP3094233), inspect and clean the motor of any obstructions.

To fix a worn drive belt, adjust the tension using the pulley system or replace the belt. Use only compatible parts for your Whirlpool Duet dryer model for an effective repair.

Defective Control Board

A defective control board can prevent a Whirlpool Duet dryer from starting. This board oversees the dryer's operations, and issues with it may result in the appliance not turning on. Burn marks near motor solder connections on the board suggest electrical problems that have damaged the board.

If such damage is observed on the control board, replacement is necessary. The control board typically has the model number 8546219, which should be used to find a compatible replacement.

When the control board is no longer available, repairing the burnt relay on the board may be an alternative. However, if a replacement is obtainable, it is advisable to replace the entire control board to enhance the dryer's efficiency and reliability.

If the Whirlpool Duet dryer does not start, the control board could be at fault. Replacing a faulty control board can help restore the dryer's functionality. Repairs should be performed by someone with the appropriate expertise or by a professional technician.
