Heating Element Basics: What to Check Before You Call a Repairman

Ever wonder why your oven won’t bake or your dryer stays cold? Most of the time it’s a tired heating element. These metal coils turn electricity into heat, so when they fail, the whole appliance goes mute. The good news? Spotting a bad element is easier than you think, and swapping it out can be a weekend DIY project.

Spotting a Bad Heating Element

First sign is usually a lack of heat. In an oven, the temperature dial will climb but the interior stays cool. A dryer might spin, but the lint trap stays damp. Listen for a humming sound when the appliance powers on – that’s the element trying to work. If you see visible cracks, discoloration, or a burnt smell, the element is likely fried.

Next, do a quick continuity test with a multimeter. Unplug the appliance, remove the element (most are held by a few screws or clips), and touch the meter probes to the terminals. A reading of zero or infinite ohms means the coil is broken and needs replacement.

Replacing the Element – Step by Step

Gather the right parts: a new heating element that matches your model, a screwdriver, safety gloves, and a multimeter for the final check. Always work on a dry surface and double‑check that the power is off at the plug or breaker.

Start by removing the old element. In ovens, you’ll usually unscrew a brass or metal bracket, then pull the element out. Dryers often have a metal cage; release the clamps and slide the coil free. Keep the mounting hardware – you’ll need it for the new part.Fit the new element into the same slots and secure it with the original screws or clips. Re‑connect any wiring, making sure terminals are tight. Before you put the appliance back together, run a quick continuity test again to confirm the new coil is good.

Put the panel or door back on, plug the unit in, and set it to a low temperature. Watch for heat to build within a few minutes. If everything works, you’ve saved a call‑out fee and learned a handy skill.

When to call a pro? If the element is hard‑to‑reach, the wiring looks damaged, or you’re not comfortable handling electricity, it’s safer to let a qualified technician step in. Also, some modern appliances use sealed heating elements that require specialist tools.

Regular maintenance can extend element life. Keep vents clean, wipe away food splatters, and avoid over‑loading dryers. A quick visual check each season helps you catch wear early, saving time and money.

Bottom line: a faulty heating element is a common, fixable problem. With a few tools and a bit of caution, you can get your oven, dryer, or water heater back to full heat in a few hours. Keep this guide handy, and you’ll know exactly what to do the next time the heat disappears.
