You probably use your dryer a few times a week. The thing about your dryer is that you need it to dry your clothes quickly. Even though you know you can air dry your clothes, your dryer will get the job done twice as fast. Because of how often you use your dryer, it’s prone to normal wear and tear.
One thing that your dryer does to let you know that something’s wrong with it is show you an error code. If you see an error code displayed on your dryer, it’s probably a mix of a letter and a number or two. If you have a Whirlpool dryer, you’ll definitely see a few error codes. Here are the meanings of the error codes that appear on your Whirlpool dryer.
Whirlpool Dryer Error Codes
PF stands for power failure. If your dryer is experiencing power failure than this means that it doesn’t have the power to start a run the cycle. One thing you can try is pressing the start button again to see if that works. If that doesn’t work then here’s what you need to do.
First you need to check the power. Whether you have a gas or electric dryer, your dryer must be plugged into a wall outlet. The breaker controlling the outlet might have tripped. First check If the dryer is plugged in. If the dryer isn’t plugged in then you need to plug it back into the outlet so that you can have the power to run it. Sometimes your dryer comes unplugged on accident Azure cleaning around it so you just want to check to see if that’s an issue.
If your dryer is plugged in and you need to see if the breaker controlling the outlet tripped. You can reset it by turning it all the way off and then on again. If your dryer is a gas dryer and is plugged into a 120-volt ground fault interrupter, then the outlet could have tripped. You can reset it by pressing the reset button on the front of the plug. If the appliances on the circuit are powered by other outlets and one of them trips that can also cut power to the dryer. Issues like this might be a reason to call a professional to check this out.
You also might have an issue with the door and start switches. The door switch is what keeps your door closed. Inspect the switch to see if it makes a clicking sound when you push it with your finger. You can also troubleshoot the start or door switch by checking the continuity with a multimeter (View on Amazon). If you want to check the starter switch, you need to lift a control panel cover by removing the two screws. The door switches are usually mounted on the dryer housing and you might be able to access it without removing the dryer cover. If either switch is having an issue and the meter measures infinite resistance, this means that these parts need a replacement.
Both of these error codes means that there’s a key stuck on your dryer. This means a key on the control panel is stuck in a certain position and it may not function because it’s stuck. This can also mean another function will not activate until a different key is unstuck. The keys can stick overtime for many reasons and unsticking them may not always mean a complex repair. One thing you should try is resetting your dryer. You can try unplugging the dryer for a few seconds and then plug it back in. This might unstick the buttons and clear the error code. If it doesn’t, you might need something more complex.
Sometimes this means that you need a control board replacement. If your keys aren’t dirty, this means the stuck error code is occurring because part of your control board is faulty. Usually the key isn’t activating the spot on the computer control board and the replacement needs to be made. The control board is specific to the brand of your dryer and replacing it can be as simple as removing the mounting screws and unplugging the wire harnesses. Reaching the control board through this assembly is the hardest part and you want to get a technician to do this so that you don’t mess up your dryer.
The dryer thermistor is attached to the blower housing and this measures the temperature inside of a dryer. If this fails completely and stops sensing the temperature, the control panel displays an error code and the dryer will stop working. This is a safety measure because if the temperature is unregulated, the dryer might malfunction and set on fire. If you think that the thermistor isn’t accurately sensing the temperature, you can check it with a meter. You should consult the manual that came with your dryer for more information about testing a thermistor. Usually the thermistor can be fixed with a replacement.
Here are the steps to replace the thermistor.
1. Shut off the power of the dryer.
2. Remove the service panel by releasing the clips to hold it in place.
3. Remove the lint duct assembly by unscrewing the screws.
4. Detach the thermistor located on top of the blower housing. Remove the wires carefully and remove the mounting screws that secure it in place.
5. Install the new thermistor in place of the old one. You’ll have to position it correctly and fasten the mounting screws.
6. Connect the wires to the new thermistor.
7. Replace the lint duct assembly and insert the mounting screws that held it in place.
8. Reinstall the service panel.
9. Restore power to your dryer. If it’s a gas dryer, turn on the gas supply.
Now the error code should be removed and you should have a working thermistor. If this repair seems too complex, then you can call a technician to do it for you.
These two error codes means that there’s something wrong with the motion sensor of your dryer. The motion sensor in your dryer consists of two metal bars on a black plate. The two metal bars protrude into the dryer’s drum. When they come into contact with the clothing, it creates a closed-circuit to allow a short electrical impulse to pass. When the moisture goes away, the current becomes weaker. When the sensors don’t detect any moisture in the clothes, the dryer can automatically turn off.
Overtime dirt, lint and even dryer sheets can cover the sensor and stop your dryer from accurately sensing when the clothes are dry. There’s a risk of under- drying or over- drying. To keep your dryer working efficiently, you need to get a damp rag and a dry rag. Find the motion sensors in your dryer. An older dryer usually has them located in the back wall of the drum. Take your damp cloth and scrub the motion sensor. Make sure you dry it when you’re done polishing it. Test your dryer to make sure it’s working correctly on a little bit of clothes.
These are the most common error codes that you’ll see on your Whirlpool dryer. Luckily these error codes tell you exactly what’s wrong with your dryer and you don’t have to do much to troubleshoot it. If anything happens, you can call it technician and they’ll fix your dryer for you so you can have a working machine again.
