Heating Element Guide: What It Is, How Much It Costs, and DIY Tips

If your oven or dryer suddenly stops heating, the culprit is usually the heating element. It’s the metal coil that turns electricity into heat, and when it quits working, your appliance feels useless. Knowing how these parts work, why they break, and what you can do about it saves you time and money.

Why Heating Elements Fail

Heat makes metal expand and contract thousands of times, and that stress creates cracks over time. A buildup of food debris or mineral deposits can also cause hot spots that burn the coil. Most failures happen after a few years of regular use, but a sudden power surge can fry an element in minutes. The good news is that a broken element is a single part, not a whole appliance, so replacement is often straightforward.

DIY Replacement vs. Hiring a Pro

Doing the swap yourself can save £50‑£150, depending on the appliance. You’ll need a screwdriver, a replacement element that matches the model, and a basic safety plan: unplug the machine, remove the old part, and install the new one the reverse way. If you’re comfortable with tools and follow the manufacturer’s guide, the job usually takes 30‑45 minutes.

Call a professional when the element is hard‑to‑reach or when you notice multiple issues, like a broken thermostat or wiring problems. A qualified tech has the right tools, knows the safety codes, and can test the whole system to prevent future breakdowns. Plus, many service providers offer a warranty on the part and labor, giving you peace of mind.

When you shop for a replacement, match the part number exactly. Generic parts are cheaper but may not fit or could burn out faster. Look for reputable suppliers that list voltage, wattage, and size. Ordering the right element the first time avoids extra trips to the hardware store.

After installation, run a quick test. Turn the appliance on for a few minutes and listen for the element’s faint hum. If it heats up quickly and stays on, you’ve done it right. If it trips the breaker or still doesn’t heat, double‑check the connections or call a pro.
