Question about Kenmore 63942 Dryer
If the model number is correct, follow these steps to access the heating element on your dryer:
1. UNPLUG the dryer. Dangerous voltage is still present inside the dryer cabinet, even when it is turned off.
2. Insert a putty knife along the top seam of the lower toe panel about 2 inches in from each side. There is a retaining clip that must be depressed on each side to release the panel. Once released, the panel will open and can be removed.
3. Open the dryer door and remove the lint screen. Then, close door and remove the lint chute directly in front of the blower fan ducting. Removing the lint hute will give you little better access.
The heating element is located inside the heater box on the right hand side. The entire heater box assembly will come out by removing a single screw on the heater box bracket in the front. You will need to carefully label and disconnect the wires to the Thermal Cut-Out (TCO) and Hi-Limit Thermostat which are mounted on the outside of the heater box on the left-hand side. The TCO is the component towards the rear of the dryer, while the Hi-Limit Thermostat is the closest to the heating element terminals. With the wires disconnnected and the mounting bracket screw removed, the whole assembly should pull out of the dryer cabinet.
If your ELECTRIC dryer is still running, but does NOT produce heat, the following two links can give you advice on how to troubleshoot an ELECTRIC dryer with a no heat problem:
IMPORTANT NOTE: Your problem may or may NOT be related to a heating element problem as there are numerous factors that can cause a dryer not to heat. The heating element has protection devices that are designed to regulate the heat and internal temperatures. If the dryer overheats the Thermal Cut-Out (TCO) typically will blow BEFORE the heating element. The replacement kit is much cheaper than purchasing a new heating element that may or may not be the problem.
Begin by unplugging the dryer and verifying the voltage at the wall receptacle. You should read 220-240VAC across the two Hot terminals (left and right slots). If the voltage is incorrect, check to make sure you don't have a breaker tripped. Some homes use 2 separate 120VAC breakers to provide power to the receptacle vice using one 240VAC breaker.
If the voltage IS correct, leave the dryer unplugged and remove the cover plate on the terminal block in the back of the dryer (this is where the power cord is installed). Plug the dryer back in and take a voltage reading across the two hot (RED and BLACK) wires at the terminal block. You should read 220-240VAC. If the voltage is good, you have an internal heating problem. If the voltage is bad at the terminal block, but good at the receptacle, you have a bad power cord.
NOTE: If the wires at the terminal block are not color coded, the outer two wires (left and right) are the hot leads. The center conductor is neutral or ground.
The reason a dryer will still run if the input voltage is incorrect, is because the drive motor only uses a portion of the 220 service. The motor runs off 110-120VAC, while the heating circuits require 220-240VAC. So, if you are missing 1/2 your input voltage due to a tripped breaker or bad power cord, your dryer may exhibit these symptoms.
If you determine the problem to be internal, the heating circuits will either be located in the rear of the dryer on the right hand, or under the dryer drum on the right hand side. Usually, an easy way to determine is by the location of the lint screen filter. If the filter is on top of the dryer, the heating circuits are in the back of the dryer. If the lint screen is in the door, the heating circuits are located under the dryer drum. If the model number you have listed is correct, your heating circuits are behind the rear panel on the right-hand side.
If either the TCO or Hi-Limit Thermostat are determined to be bad, replace BOTH components at the same time. That is why these components are commonly sold as a set. Failure to do so may result in premature failure of any parts you replace.
Replacement parts (if required) may be found at the following websites:
The average cost of these components varies, so shop and compare. The first three websites I listed have helpful exploded view parts diagrams that can help you locate and properly identify any parts you may need. The heating components are usually listed under the "Bulkhead" section.
If you have any questions, please post back and let me know. I hope you find this information helpful.
NOTE: If your model number is not listed on some of the websites, use the part numbers from the Sears website and use that as your search criteria. Some model numbers will not reference on some sites, but the part numbers will.
