Kenmore Dryer not Drying
Model #110.62182100, this electric dryer, made by Whirlpool, was doing all the normal things dryers do, other than heating to dry the clothes. The problem had suddenly occurred between load of laundry, where it worked for one load, but the other was still considerably damp at the end of the cycle. The customer did some checking of the airflow coming out of the vent on the outside of the house, and it seemed to be good, but without the heat, this dryer wasn’t going to work.
As I have covered in other posts, dryers that are not heating can be the result of several electrical and mechanical components. In general, most dryers are pretty simple in their design and by defining the problem, we can easily isolate the portion of the unit we need to begin our investigation. Then we simple start checking each of the components until we find the one that is causing the problem.
A good place to begin any not heating problem is the power source. Since these dryers run on 240 voltage AC, there are two electrical circuits that run into the back of the dryer. One is generally used for all the normal dryer operations from the motor to the control board, while the other circuit is dedicated to the heating element. If the motor is running, we know there is power to the dryer, but it is still possible for the dryer not to heat. So a simple suggestion is to turn the dryer circuit off, then back on at the breaker panel. If that doesn’t solve the problem, then it’s time to get out a multimeter and start taking some measurements.
Since the customer already tried the circuit breaker trick, I heading into the back of the dryer with meter in hand to have a look for a failed component. When looking at the back of these dryers, there are a few safety devices that are designed to open the circuit in the event of a runaway heating condition due to a blocked or otherwise restricted vent system. These components should all read as a closed circuit if they are functioning properly and an open circuit if they have failed. As I went through each component one by one, they all checked out as good, which then brought me to the heating element itself. A resistance check of the element showed it to be an open circuit which would explain why there was no heat from the dryer.
The elements are usually wire coils mounted inside a housing allowing air to be drawn through by the blower wheel and into the drum. Held in place with a couple screws, I removed the housing from the heater duct and was quickly able to see the break in the heating coil. This break opened the electrical circuit and without a complete circuit, this element was no longer going to heat.
A new heating element was installed in place of the old element and the wires connected. With the unit plugged back in, a test cycle was started and after a very short period of time, the heat could be felt coming from the vent. I put the rear panel back in place ensuring the vent was not restricting any airflow. After the initial hot smell from the new element went away, the dryer was again ready for use.
