To troubleshoot a Whirlpool Duet dryer, begin by isolating the problem and its most common solutions. An ohmmeter and other basic tools are required to troubleshoot electrical devices.
Typically, Whirlpool Duet dryers display an error code if there is a problem with the operation of the dryer. For instance, the code E1 indicates an improper exhaust temperature on most Whirlpool dryers. Identify the error code by checking the display panel on the dryer, and then begin isolating the most common solutions for the error code.
Typically, it is recommended to begin repairing the dryer by making the most common repairs first, particularly when the cause of the malfunction is unknown. For instance, it is very common for the heating element to malfunction in dryers, so this part should be replaced first if the dryer stops heating properly.
An ohmmeter can be used to troubleshoot electrical parts, such as the main circuit board in the dryer. Other simple solutions include determining whether the dryer is receiving power by opening the door and checking to see if the light inside the dryer turns on. If the light is on, the dryer is typically receiving power and the problem doesn't include the power cord, outlet or main electrical components.
When troubleshooting a Whirlpool Duet dryer, set the controls to diagnostic mode, if possible. Unplugging the dryer or turning off the power at the breaker is recommended when opening any panels on the dryer.
