An electric dryer that tumbles happily but leaves the clothes cold and damp very often has a burned-out heating element. But not always. Electric dryers run on 240 volts, and losing half of that supply produces almost exactly the same symptoms. A blown thermal fuse or a tired thermostat can look the same from the outside as well.
Before anyone orders an element, it is worth knowing the signs of a failed one, the other parts that mimic it, and the simple check at the breaker panel that solves a surprising number of no-heat calls. Here is how we approach it on service calls around Calgary.
How the heating element works
The element is a long coil of resistance wire held on ceramic insulators inside a metal housing, usually behind the drum or along the back of the cabinet. The blower pulls room air across the glowing coil and into the drum, then pushes the damp air out through the vent. Like the wire in a toaster, the coil eventually breaks. Once it is open, there is no path for current and no heat, while the motor, drum and timer keep working normally.
The element does not work alone. It is wired in series with safety parts: a high-limit thermostat, a thermal fuse on many models, and a cycling thermostat or thermistor that the control uses to hold the right temperature. If any one of those opens, the element goes cold too.
Signs the element has failed
Cold air on every setting
The clearest sign is a drum that turns while the air stays cold on every heat setting, from low to high. The clothes come out at room temperature after a full cycle.
Heat that faded before it stopped
A coil can sag, stretch or partly short before it fails completely. Owners often notice loads taking longer and longer for a few weeks, and then one day there is no heat at all. Some dryers use an element with two coils, and one coil can fail on its own, leaving heat on some settings only. See dryer heats on some settings only for that pattern.
A brief burning smell, then nothing
When a broken coil end flops against its metal housing, it can arc for a moment and give off a sharp electrical smell before the heat quits. If you notice smoke or a strong smell, stop using the dryer and read our post on dryer burning smells.
Error codes on electronic models
Many newer dryers report a heater problem directly. Whirlpool's F4 E1 is a heater system fault. On Electrolux, E64 is a heater open circuit and E63 is a heater shorted to ground. Bosch E63 is a heating element failure, and Frigidaire's E5B means the temperature is not rising. You can look up your code on our error code page.
Parts that look like a bad element
A no-heat dryer has several possible culprits, and they are tested in a logical order. This table shows how each one usually behaves.
| Part | Typical signs of failure | Who fixes it |
|---|---|---|
| Breaker leg | Tumbles, no heat, sudden onset | DIY reset; electrician if it trips |
| Heating element | No heat, or heat fading over weeks | Technician |
| Thermal fuse | No heat after a long, hot cycle | Technician, plus vent check |
| High-limit thermostat | No heat, often with poor airflow | Technician |
| Cycling thermostat or thermistor | Too hot, too cool, or uneven heat | Technician |
| Heater relay on control | Heat code with a good element | Technician |
Why heating elements burn out
Elements are built to last many years, so an early failure usually has a cause behind it. Replacing the coil without fixing that cause often means another no-heat call within months.
- Restricted airflow. A clogged lint screen, a crushed transition duct or a vent packed with lint means less air moves across the coil. The coil runs hotter, the high-limit cycles more often, and the wire weakens. Our post on how often to clean a dryer vent sets out a sensible routine.
- Lint inside the cabinet. Lint that escapes the screen can settle on the element housing. It scorches, smells and adds to the heat stress on nearby wiring.
- Overloaded drums. A packed drum blocks airflow through the load and keeps the element on for longer cycles.
- Loose connections. A terminal that has worked loose heats up, discolours and can burn through the coil end or its wire.
- Age. Heating and cooling thousands of times eventually tires the wire, even in a well-vented dryer.
That is why we check airflow and the wiring to the element as part of every heating repair, not just the part that failed.
The 240 V double-breaker check
This is the check that saves the most service calls. An electric dryer is fed by a double breaker: two breakers joined by a handle tie. One leg runs the motor and controls on 120 V, but the heater needs both legs for 240 V. If only one leg trips, the dryer runs and tumbles normally but makes no heat. It looks exactly like a dead element.
Some dryers tell you directly. LG's nP code means no current is detected at the heater, often from a tripped breaker leg, and our LG nP code guide walks through it. Whirlpool's L2 means low or no line voltage, so the heater may not turn on, and F4 E4 means low or no line voltage to the heater. Owners of Whirlpool, Maytag and Kenmore models can find the full list on our Whirlpool code section.
To check safely:
- Find the dryer breaker in your panel. It is usually labelled and twice as wide as a regular breaker.
- Switch it fully off, then firmly back on. A half-tripped breaker can look like it is on.
- Run a heated cycle and feel for warm air after a few minutes.
If the breaker trips again, leave it off. A breaker that keeps tripping can point to a shorted element or a wiring fault, and resetting it over and over is not safe. Never take the panel cover off or work on the wiring yourself.
Safe checks before you call
Unplug the dryer or switch off its breaker before you touch anything.
- Reset the double breaker as described above.
- Clean the lint screen and confirm strong airflow at the outside vent hood.
- Check the cycle and temperature settings. Air fluff and some delicate settings use little or no heat, and a child lock or eco option can change how a cycle behaves.
- Write down any codes on the display and roughly when the heat stopped.
- Note whether the dryer has been running unusually hot lately. That detail helps us find the root cause.
Do not open the cabinet to test the element with the power on, and do not bypass the thermal fuse or high-limit thermostat. Testing should be done with the power off and the right meter. Our dryer not heating checklist goes through the order we use.
When to call a technician
If the breaker is fine and there is still no heat, the element, thermal fuse, high-limit, thermostat or control needs proper testing.
