Your Whirlpool dryer won’t start? It’s a common problem with many possible causes. The good news is that it’s an uncomplicated repair job.
Generally, all whirlpool dryers use the same basic control board, making diagnosing and fixing the problem fairly straightforward.
Furthermore, most of the Whirlpool dryers also tend to malfunction in exactly the same ways again and again.
Here are some of the most frequent fixes for a Whirlpool dryer that won’t start, along with the solutions and tips to avoid these problems in the future. Let’s get started!
12 Most Common Reasons Why Whirlpool Dryer Won’t Start
There can be several reasons Why a whirlpool dryer won’t start. Before getting started with this troubleshooting guide,
you need to have the user manual ready. Furthermore, make sure you have basic tools like a screwdriver or a tool kit that will help you open the dryer.
Also, if you don’t know anything about the dryer, it is best to get your dryer repaired by a technician, or else you will break it for sure.
Apart from that, while you are repairing your dryer, you need to replace some components, so you need to find out the replacement unit,
which may be difficult, but usually, you can find them at a local repair shop or from online stores.
1. Dryer Not Receiving Power
The most basic cause of a Whirlpool dryer that won’t start is that the machine isn’t receiving power.
Make sure your Whirlpool dryer is properly plugged into the power outlet and the switch is turned on.
Further, you need to ensure that you have pressed the power button on the dryer.
The power outlet has some breakers or fuses, so you need to ensure that the power outlet is working fine.
You can check the power outlet by unplugging the dryer and plugging any other device into the outlet.
If the breaker has not tripped and the power fuse is not blown, then you can check the outlet for power with a plug-in appliance tester.
If no power is showing, you’ll need to hire an electrician to find the problem and fix it. If you find power at the outlet, the problem may be with the machine itself.
On top of that, if you are using an extension cord, there is a high chance that the problem is with the extension cord.
You need to make sure that the extension cord is transmitting power to the dryer.
2. Incorrect Dryer Settings
One of the most common causes of a Whirlpool dryer that won’t start is incorrect dryer settings.
If the dryer is receiving proper power, but it is not running as intended, then you need to make sure that you’ve set the machine for the type of load you’re putting in it: clothes, towels, sheets, etc.
Make sure you’ve selected the right heat setting for the type of load you’re drying.
If the settings are correct, and you’ve cleaned the lint filter, there’s a chance the machine has simply entered an error cycle.
Press the Cancel button to reset the dryer and try again. If it happens again, the machine may be faulty.
Different whirlpool dryers have different settings, and if you are not sure what settings you should use for the specific load, you can set the dryer to Automatic or Timed cycle.
Also, if you have mistakenly selected the Wrinkle Reduction option, the dryer won’t run.
3. Child Lock is On
Almost all of the Whirlpool dryers come with a child lock function to prevent unwanted starts and button presses.
Sometimes the child lock gets turned on unintentionally when you mistakenly press the buttons on the dryer, and this makes the dryer not run.
You need to make sure that the child lock is not on while using the dryer. Most of the modern Whirlpool dryer models have a child lock icon that glows when turned on,
and you need to disable it by pressing the Start button for 3 seconds.
Moreover, some old models of Whirlpool dryers require you to press a combination of buttons to disable the child lock, so you can check it in your user manual.
4. Tripped Circuit Breaker
When you use multiple large appliances at the same time, it is possible to trip the circuit breaker.
If the circuit breaker has tripped, the dryer won’t run.
To fix this issue, you need to inspect the circuit breaker, and you need to be sure that the fuses are tight and intact.
However, if they have tripped, you need to replace them. Furthermore, you can reset the breaker.
5. The Dryer Door is Not Latched
If the dryer door isn’t latched, the whirlpool dryer won’t turn on. Whenever you close the dryer’s door,
it always gives a click sound which confirms that the door has been properly latched.
You can test this by unplugging the machine and manually opening and closing the door.
If the door is not working after properly latching the door, then there is something wrong with the door switch,
and it will probably need a replacement. If you want to replace the door switch, then you can check out method no 7.
Pro Tip: If you want to avoid door latch malfunctions, you should prevent slamming the door while closing it.
You can gently shut the door, which will extend the life of the locks and door switch in your Whirlpool dryer.
6. Blown Thermal Fuse
A thermal fuse is one of the crucial components in your Whirlpool dryers that prevents the dryer from getting fires, as it can easily detect the overheating inside the drum.
Moreover, it is a crucial safety component, and if it stops working, the dryer won’t run.
Thankfully, a thermal fuse is a common component, and it is readily available in local repair shops.
Furthermore, it is very cheap, so you can easily replace it yourself.
How to Replace a Thermal Fuse in Whirlpool Dryer?
First of all, you need to identify that it is the thermal fuse that is preventing the dryer from starting.
You can use a multimeter to test the continuity of the thermal fuse.
While replacing a thermal fuse, you should always check the dryer’s vents, and if they are clogged, you need to clean them out before replacing the thermal fuse.
It is because the vents get clogged, due to which the dryer’s drum starts overheating, which leads to a blown thermal fuse.
- Shut off your whirlpool dryer and unplug it.
- Remove the back panel using a ¼ inch nut driver and set the panel aside.
- Next, locate the thermal fuse using the user manual. You will be easily able to locate the thermal fuse as it gets exposed as soon as you take off the back panel.
- Remove the thermal fuse using a ¼ inch nut drive and then pull the fuse off from the blower’s housing.
- After that, install a new thermal fuse in place and secure it with the mounting screws. Connect the wires and then push them into the blower’s housing.
- Reattach the dryer’s back panel and plug the dryer to test it out.
7. Defective Start Switch
If the dryer doesn’t start, the start switch may be faulty. The start switch is an electromechanical device that uses a solenoid, a switch, and a spring to control the start cycle.
If the dryer’s start switch is faulty, you’ll need to replace it.
Start switches are sold as a kit, with the solenoid and a variety of switches.
You’ll need to figure out which switch your dryer uses before you can buy a replacement.
Start switch problems are uncommon, but they are not difficult and expensive to repair.
You can turn on the dryer, and if the dryer doesn’t start, but it hums, then the start switch is working fine.
However, if the dryer doesn’t respond or make any sound, it could be the start switch that is defective. You can test the start switch using a multimeter for continuity.

Motors rarely go bad, but they are expensive and difficult to repair.
9. Defective Belt Switch
The belt switch is another vital component in any dryer. Some of the Whirlpool dryers come with a belt switch, while some don’t have a belt switch.
The belt switch is responsible for operating the motor, and if it breaks, the dryer will turn on, but the drum won’t rotate.
You can identify a broken belt switch by listening to any humming sound coming from the dryer.
