Understanding Your Dryer's Heating Element
The heating element is one of the most important parts of your electric dryer. It works by converting electricity into heat, which warms the air inside the dryer drum. When you turn on your dryer, electricity flows through a wire coil. This coil has high resistance to electrical flow, which causes it to become extremely hot—sometimes reaching 5,000 degrees Fahrenheit or higher. The heating element typically lasts between 3 to 5 years with regular use, though this varies based on how often you run your dryer and how well you maintain it.

Most electric dryers use one main heating element, though some models have secondary heating elements. The element sits behind the dryer drum and may be difficult to see without opening the machine. Gas dryers work differently and do not have electric heating elements; they use a gas burner instead. If you own a gas dryer, you will not need to replace an electric heating element.
When a heating element fails, your dryer will still run and tumble clothes, but it will not produce heat. This is different from other problems like a broken door latch or a stuck lint trap, which may prevent the dryer from running at all. The heating element can fail gradually, meaning your dryer may produce less heat over time before stopping completely. Some dryers also have thermal fuses that protect the heating element by stopping the dryer if it overheats.
Practical takeaway: Before attempting any repair, confirm your dryer is electric, not gas. Look at your dryer's manual or the nameplate on the back to verify the model type. Understanding how your heating element works helps you recognize when it needs replacement and understand the repair process.
Signs Your Heating Element May Need Replacement
Several warning signs suggest your dryer's heating element is failing or no longer working. The most obvious sign is that your dryer no longer heats clothes at all. You may run a full cycle and find that clothes come out completely dry to the touch but not warm. This happens because the motor still spins the drum, but no heat is generated.

A second sign is reduced heat output. Your dryer may take significantly longer to dry clothes than it used to. What previously took 30 minutes might now take an hour or more. You may notice that clothes are slightly damp after a normal cycle. This gradual decline in heating power often precedes complete heating element failure.
Some dryers produce a burning smell when the heating element is failing. This smell may come from damaged wiring or dust that has accumulated on the heating element. If you notice a burning odor, stop using the dryer immediately and unplug it from the electrical outlet. Do not attempt to run the dryer again until you have investigated the source of the smell.
Keep in mind that other problems can also cause heating issues. A clogged lint trap or blocked vent hose restricts airflow and makes dryers less efficient. Blown thermal fuses prevent heating element activation as a safety measure. A malfunctioning thermostat can also cause heating problems. These issues are often easier and less expensive to fix than replacing a heating element, so it is worth checking these components first.
Practical takeaway: Document what you observe about your dryer's performance. Write down when the problem started, whether heat is completely absent or reduced, and any unusual smells. This information will help you troubleshoot and communicate the problem to a repair professional if you decide to hire one.
How to Locate Your Dryer Model Information
Finding the correct heating element for your specific dryer model is essential. Heating elements vary significantly between manufacturers and even between different model years from the same manufacturer. Using the wrong heating element can result in poor performance, safety hazards, or damage to your dryer.

The model number is typically located on a nameplate attached to your dryer. For most dryers, this nameplate is on the back wall inside the dryer cabinet, near where the lint trap sits. You may need to open the dryer door and look toward the top or side interior walls. Some dryers have the nameplate on the exterior back panel. Less commonly, it may be on the side of the machine or under the front panel.
Once you find the nameplate, look for text that says "Model" followed by a number. Write down the entire model number exactly as it appears. The model number may include letters and numbers and can be quite long. For example, a typical model number might look like "LGD5678WW" or "WHIRLPOOL_MAYTAG_WED7120HW". You will also see other information on the nameplate, such as the serial number (which you do not need for parts), voltage information, and manufacturing date.
If you cannot find the nameplate or it is illegible, you can sometimes find the model number in your owner's manual. The manual may be in a drawer near your dryer or available online through the manufacturer's website. You can search for your dryer brand and the words "owner's manual" to locate one. Another option is to contact the dryer manufacturer directly and provide them with your serial number and any other identifying information on the nameplate.
Practical takeaway: Before shopping for any parts, take a photo of your dryer's nameplate with your phone. Include the model number clearly in the photo. This photo serves as a reliable reference when researching parts online or consulting with repair professionals. Keep this information in a note on your phone or email it to yourself for future reference.
Researching and Locating the Correct Heating Element
Once you have your model number, you can research which heating element your dryer requires. Several resources can help you find this information. The manufacturer's official website usually allows you to search by model number and view a parts diagram. This diagram shows every component in your dryer and assigns each part a part number. The part number for the heating element is what you need to purchase the correct replacement.

Appliance parts retailers online and in stores carry heating elements for most common dryer models. Large retailers that specialize in appliance parts often maintain searchable databases on their websites. You enter your dryer model number, and the system displays compatible parts with their part numbers and prices. This method is reliable because the database is typically maintained to ensure accuracy.
Video guides and repair forums specific to your dryer model can also provide information about which heating element you need. Many appliance repair websites include parts lists and diagrams. YouTube contains numerous videos showing heating element replacement for specific dryer models. These videos often display the heating element clearly and may mention the part number during the repair process.
Heating element prices vary considerably based on the brand and quality. Aftermarket heating elements from third-party manufacturers typically cost between $100 and $250. Original equipment manufacturer (OEM) elements from the dryer brand itself may cost $150 to $400 or more. Some aftermarket elements are made with materials designed to last longer or perform better than standard elements. Reading reviews from other customers who purchased the same part can help you assess quality and reliability. Be cautious of extremely low-priced elements, as they may fail quickly, requiring another replacement soon.
Practical takeaway: Compare prices across multiple retailers before purchasing. Many appliance parts retailers offer the same part at different prices. Saving $30 to $50 on the part itself is worthwhile, and some retailers offer free shipping on larger purchases. Create a list of the part numbers and prices from different sources to make an informed decision about where to buy.
Preparing for Dryer Heating Element Replacement
Replacing a heating element involves working with electrical components and disassembling your dryer. Understanding what this process requires helps you decide whether to do the work yourself or hire a professional repair person. Many people successfully replace heating elements on their own, but the task does require mechanical aptitude, appropriate tools, and time.

To replace a heating element yourself, you will need basic tools including a screwdriver (usually Phillips head), possibly a socket wrench set, and a flashlight. Some dryer models may require a dryer disassembly kit or specialized tool, though this is uncommon. You will also need a work surface—ideally a large, clean area where you can lay out the dryer and keep track of screws and small parts. Many people work in their garage or laundry room with the dryer pulled away from the wall.
Before beginning any work, you must disconnect electrical power. For electric dryers, unplug the machine from the wall outlet. If
