A beeping Kenmore front-load dryer can be irritating, especially if you can't make the noise stop or determine why it's occurring. Depending on your dryer model, the noise is most likely the dryer alerting you of a problem; it usually accompanies an error code that displays on the dryer's control panel to help you identify the specific issue. However, sometimes the noise is just to indicate that the dryer has finished a drying cycle, so you can remove clothes before they wrinkle. Perform a preliminary inspection of your dryer before you pull out its manual to diagnose the problem.
End of Cycle
It's normal for certain Kenmore front-load dryers to beep when a drying cycle ends. The noise is to let you know that clothes are dry and ready to be removed. Some models will beep once, others will beep several times in a series, and some will beep at regular intervals to confirm or remind you that a cycle is over. Open the washer's door to stop it from beeping or press "Pause" or "Stop" on the dryer's control panel to silence the dryer until you're ready to empty it.
Running a diagnostic test could cause a Kenmore front-load dryer to beep continuously during the test or if it gets stuck in diagnostic mode. In this mode, a dryer will beep every time you make a change to the dryer's state, such as opening and closing the door, choosing a cycle setting or pressing "Start." Stop the diagnostic test by holding down both the "Pause/Cancel" and "Select" buttons at the same time for at least six seconds to reset the dryer to normal function. If this doesn't reset the dryer, unplug its power cord from the electrical outlet and wait one minute before plugging it back in. Cutting its power source should reset the dryer and stop it from beeping.
Error Code Alert
An error code alert could make a Kenmore front-load dryer beep nonstop. On certain dryers that don't have digital displays, the beep is intended to inform you of a problem; the display lights on the machine will blink in series to relay an error code so you can identify and fix the issue. To determine the problem, count the number of times the Drying, Cool Down, Wrinkle Rid and Clean Lint Filter lights flash to get the first number of the two-digit error code. Then, count the number of flashes made by the Start indicator light to get the second number. Once you have the error code, look it up in your dryer's manual or contact Kenmore for additional information.
Failed Temperature Sensor
Kenmore dryers will beep incessantly when the temperature sensor or thermistor fails. Review the manual for your dryer to confirm that your dryer has this component and to determine its location. Accessing the sensor usually requires that you remove the front lower panel of your dryer. Once the panel is removed, you can test the sensor's voltage with a multimeter or contact Kenmore to have a technician test it for you. The sensor should provide a reading of 50,000 ohms at room temperature. If the voltage is lower, it means the sensor is bad and must be replaced.
