How to Replace the Heating Element in a Kenmore Dryer?
Replacing the heating element in a Kenmore dryer is a manageable DIY project that can save you money. This article provides a step-by-step guide to safely and effectively replace the heating element, restoring your dryer to its full heating capacity and avoiding costly appliance repair services.
Understanding Your Kenmore Dryer’s Heating System
A Kenmore dryer relies on a heating element, often located in the rear of the unit, to generate the hot air needed to dry your clothes. Over time, this element can burn out or become damaged, leading to a lack of heat and extended drying times. Knowing the basics of the heating system helps in troubleshooting and replacement.
- Heating Element: The core component that generates heat. It consists of coils of wire that resist electrical current, creating heat.
- Thermostat: Controls the temperature inside the dryer drum. It cycles the heating element on and off to maintain the selected heat setting.
- Thermal Fuse: A safety device that shuts off the dryer if it overheats.
- High-Limit Thermostat: Another safety device that monitors the temperature of the heating element and shuts it off if it gets too hot.
Benefits of DIY Heating Element Replacement
Why tackle this repair yourself? Several benefits make DIY heating element replacement an appealing option:
- Cost Savings: Repair services can be expensive. Replacing the element yourself significantly reduces expenses, only requiring the cost of the new element.
- Convenience: You avoid scheduling appointments and waiting for a repair technician. You can fix the dryer at your own pace.
- Learning Experience: It’s an opportunity to learn about your appliance and gain valuable repair skills.
- Quick Turnaround: Assuming you have the right tools and parts, the repair can often be completed in a few hours.
Step-by-Step Guide to Replacing the Heating Element
Before starting, always disconnect the dryer from the power supply and turn off the gas supply if you have a gas dryer. Safety is paramount.
Gather Your Tools and Materials:
- New Heating Element (matching your Kenmore dryer model number)
- Screwdriver (Phillips and flathead)
- Nut driver set or socket set
- Pliers
- Multimeter (to test the old element)
- Work gloves
- Safety glasses
Accessing the Heating Element:
- Unplug the dryer from the electrical outlet. If it’s a gas dryer, shut off the gas supply.
- Locate the access panel on the back of the dryer. This is usually held in place by screws. Remove the screws and the panel.
- Identify the heating element housing. It’s typically a metal box located near the bottom of the dryer.
Removing the Old Heating Element:
- Disconnect the wires connected to the heating element terminals. Take a photo before disconnecting to ensure proper reconnection later.
- Remove the screws holding the heating element housing in place.
- Carefully remove the heating element housing from the dryer.
- Remove the heating element from the housing. This may involve removing a few more screws.
Installing the New Heating Element:
- Place the new heating element into the housing, ensuring it is properly seated.
- Secure the heating element in the housing with the screws you removed earlier.
- Reinstall the heating element housing back into the dryer.
- Reconnect the wires to the heating element terminals, referring to the photo you took earlier.
Testing and Reassembly:
- Before reassembling, test the new heating element with a multimeter to ensure it has continuity. If there’s no continuity, double-check the connections.
- Reinstall the access panel on the back of the dryer.
- Plug the dryer back into the electrical outlet. If it’s a gas dryer, turn on the gas supply.
- Run a test cycle to ensure the dryer is heating properly.
Common Mistakes and How to Avoid Them
- Forgetting to Disconnect Power: This is extremely dangerous. Always disconnect the power before starting any appliance repair.
- Incorrect Wiring: Take a picture of the wiring before disconnecting anything to ensure proper reassembly.
- Using the Wrong Heating Element: Always verify the part number of the new heating element matches your dryer model.
- Damaging the Thermal Fuse or Thermostat: Handle these components carefully, as they are essential for safety.
- Skipping the Testing Phase: Always test the new element with a multimeter before reassembling everything to avoid unnecessary work.

Frequently Asked Questions (FAQs)
How do I know if my Kenmore dryer’s heating element is bad?
The most common symptom of a bad heating element is that the dryer runs, but clothes don’t dry or take significantly longer to dry. You might also notice a burning smell or the dryer shuts off prematurely. A multimeter can confirm if the element lacks continuity.
Where can I find the correct replacement heating element for my Kenmore dryer?
The best place to find the correct replacement is by searching online using your dryer’s model number, which is usually found on a sticker inside the dryer door or on the back of the unit. Major appliance part retailers or the Kenmore website are good resources.
Can I replace a heating element in a gas dryer the same way as an electric dryer?
The process is similar in accessing and replacing the heating element. However, gas dryers have additional components like a gas valve. Always shut off the gas supply before working on a gas dryer, and if you are uncomfortable working with gas, consult a qualified technician.
What does continuity mean, and how do I test for it with a multimeter?
Continuity refers to the presence of an unbroken electrical path. To test, set your multimeter to the continuity setting (often represented by a diode symbol). Touch the probes to the terminals of the heating element. If the multimeter beeps or shows a reading near zero, the element has continuity and is likely good. No beep or an infinite resistance indicates a broken circuit and a bad heating element.
What other parts should I inspect or replace when replacing the heating element?
Inspect the thermal fuse, high-limit thermostat, and the dryer vent hose. These components can be affected by overheating. A clogged vent can cause the heating element to fail prematurely, so ensure it is clean. Consider replacing the thermal fuse as a preventative measure.
How long does it typically take to replace a dryer heating element?
For someone with basic DIY skills, it usually takes between 30 minutes to 2 hours to replace a dryer heating element, depending on the dryer model and your experience level.
What is the average cost of a replacement heating element for a Kenmore dryer?
The average cost of a replacement heating element typically ranges from $20 to $80, depending on the model and brand.
Is it safe to run my dryer with a broken heating element?
It’s generally not recommended to run your dryer with a broken heating element. While it might still tumble clothes, it won’t dry them effectively and could potentially damage the dryer or create a fire hazard if other safety components fail.
What causes a heating element to fail in the first place?
Overheating is the primary cause of heating element failure. This can be due to a clogged dryer vent, a malfunctioning thermostat, or simply normal wear and tear over time. Regular vent cleaning is crucial for preventing premature element failure.
How often should I clean my dryer vent?
It is recommended to clean your dryer vent at least once a year, or more frequently if you notice reduced airflow or longer drying times. A clogged vent poses a serious fire hazard.
Can I upgrade to a more efficient heating element?
While upgrading to a different type of heating element isn’t usually possible, ensuring you choose a high-quality replacement part designed for your specific dryer model is key to maximizing efficiency and longevity.
What should I do if I’m uncomfortable performing this repair myself?
If you’re not comfortable with electrical repairs or feel unsure about any step of the process, it’s always best to consult a qualified appliance repair technician. Safety is paramount, and a professional can ensure the repair is done correctly and safely.
