Faulty Heater Element – Spot the Problem, Test It, and Fix It Fast

Ever wonder why your oven, dryer, or water heater just won’t get hot? Most of the time the culprit is a heater element that’s gone bad. A broken element can leave you with cold meals, lukewarm showers, and a hefty energy bill. The good news? You can often check and replace the part yourself, saving time and money.

How to Test a Heater Element

First, unplug the appliance or turn off the breaker. Safety always comes first. Next, locate the element – it’s the long, metal coil you see inside the oven oven wall, dryer drum, or water heater tank. Remove any screws or brackets holding it in place and pull the element out gently.

Now grab a multimeter and set it to the "ohms" (Ω) setting. Touch one probe to each terminal on the element. A healthy coil usually reads between 10 and 30 ohms. If the meter shows infinite resistance (no continuity) or a reading far outside that range, the element is busted and needs replacement.

While you have the element out, give it a quick visual check. Look for obvious signs like broken wires, burnt spots, or a gray, powdery coating. These clues confirm a failure even before you test.

When to DIY and When to Call a Pro

If the test shows a bad element and you feel comfortable handling basic tools, swapping it out is straightforward. Most elements attach with two screws and a couple of wires. Make a note of how the wires connect, snap the old element out, plug the new one in the same way, and bolt it back in place.

However, some situations call for a professional. If the appliance still won’t heat after you replace the element, the problem could be in the thermostat, wiring, or control board – things that need a qualified electrician’s eye. Also, if you’re dealing with a gas‑powered heater, or if the appliance is still under warranty, let a pro handle it to avoid voiding coverage.

Finally, remember to restore power, run a quick test cycle, and make sure everything heats up evenly. If you notice any odd smells or sparks, shut it down immediately and call a specialist.

With these steps, you can diagnose a faulty heater element quickly, decide whether a DIY fix is right for you, and keep your home running warm and efficient.
