Heating Element Test: How to Check If Your Appliance’s Core Is Working

When working with heating element test, a procedure that measures the resistance of a heating component to confirm it’s still conductive. Also known as element continuity check, it helps keep ovens, water heaters, and other commercial gear humming.

A heating element, the resistive coil that turns electricity into heat in appliances like ovens and water heaters is the heart of any hot‑air or hot‑water system. When that coil fails, the whole machine can feel dead. The most common way to verify the coil’s health is with a multimeter, a handheld tool that measures voltage, current, and resistance. By checking continuity, you can tell whether the element is cracked, burned out, or still good.

Why the Test Matters for Commercial Kitchens

In a busy kitchen, a non‑heating oven means lost orders and frustrated staff. A broken water‑heater element can stall dishwashing cycles and force you to serve cold dishes. Running a heating element test before the problem escalates saves time and money. It also gives you concrete data to show a landlord or insurance adjuster, proving the fault isn’t due to user error.

Three key relationships drive the importance of the test: the appliance relies on the heating element to generate heat, the multimeter provides the data needed to assess that element, and the result determines whether you repair or replace. In practice, a technician will disconnect power, remove the element, set the multimeter to ohms, and look for a reading between 10 and 30 Ω for most electric ovens. Anything outside that range signals a problem.

Beyond ovens, the same steps apply to water heaters, commercial fryers, and even industrial dryers. A faulty element in a water heater shows up as lukewarm showers or a dishwasher that won’t finish its cycle. The test pinpoints the culprit, so you don’t waste hours swapping unrelated parts.

Knowing how to perform the test also helps you spot related issues. For example, if a multimeter reads infinite resistance, the element is open; if it reads zero, the element is shorted, which can trip circuit breakers. Both conditions are dangerous and warrant professional attention.

Our collection of articles below walks you through each scenario. Whether you’re checking an oven that won’t heat, a water heater that’s sputtering, or a commercial extractor fan that’s acting up, you’ll find step‑by‑step guides, safety tips, and cost‑benefit analyses to decide when to DIY and when to call Birmingham Commercial Appliance Repair Services.
