Heater Element Issues: Quick Guide for Homeowners

If your oven isn’t heating, your water isn’t hot, or your dryer feels weak, the culprit is often the heater element. It’s the part that turns electricity into heat, and when it fails, the whole appliance can feel useless. Below you’ll find easy ways to tell if the element’s gone bad, what you can safely test yourself, and when it’s best to let a professional handle it.

What a Heater Element Does

A heater element is a metal coil or strip that gets hot when electricity passes through it. You’ll find them in ovens, microwaves, water heaters, dryers and even some dishwashers. Their job is simple: create heat so the appliance can do its thing. Because they run hot for a long time, they can wear out, crack, or get coated with mineral deposits.

Common Signs It’s Going Bad

Here are the red flags that usually point to a bad element:

  • Appliance heats slowly or not at all.
  • Humming or buzzing noise without heat.
  • Visible cracks, blistering or black spots on the coil.
  • Tripped circuit breaker when the appliance is turned on.
  • Strange smells like burning plastic.

If you notice any of these, stop using the appliance and check the element.

DIY safety check: Unplug the appliance, locate the element (usually behind a panel), and look for obvious damage. With a multimeter set to “ohms,” test the coil for continuity. A reading of infinite resistance means the element is broken and needs replacement.

Don’t try to repair a cracked coil yourself – it’s not a fix you can patch. Replacing the whole element is the usual solution.

When you’ve confirmed the element is bad, decide whether you’ll replace it yourself or call a repair service. Replacing an oven element, for example, costs around £30‑£60 for the part plus a small labor fee. Water heater elements are a bit pricier, typically £40‑£80, but the job is still straightforward for a handy homeowner.

If you’re not comfortable with electrical work, especially in hard‑wired appliances like boilers or built‑in ovens, it’s safer to call a Northampton repair pro. They have the tools, knowledge of local wiring codes and insurance to do the job without risking a fire.

Tips to extend element life:

  • Run appliances on appropriate temperature settings – don’t crank the oven to 500°C for everyday cooking.
  • Descale water heaters regularly if you have hard water.
  • Keep the area around the element clean and free of food debris.
  • Avoid short‑cycling the dryer – let it run a full cycle before turning it off.

Simple maintenance can add years to the element’s lifespan and save you a callout fee.

In short, a faulty heater element shows up as no heat, odd noises, or visible damage. A quick visual inspection and continuity test will tell you if it’s broken. Replace it yourself if you’re comfortable with basic electrical work, or call a local repair service for peace of mind. Either way, catching the problem early means you won’t be left without hot water or a usable oven for long.
