FAQ: How To Test A Tumble Dryer Heating Element?

How can you tell if a heating element is bad?

Touch a probe on the multitester to each screw on the element. If you get no reading, or a maximum reading, the element is bad. Elements do have some resistance, so a reading of 10-16 ohms is normal, with higher ohm readings for 3,500 watt elements and lower readings for 5,500 watt elements.

How do you know if your dryer heating element is going out?

If the heating element isn’t working properly, the dryer will still spin and the cycle will complete, but it won’t get hot enough to help dry the clothes. Heating elements can naturally wear out over time, but overloading the dryer, not cleaning the lint screen and poor ventilation can all speed up that process.

How many ohms should a dryer heating element read?

The ideal reading for a tumble dryer element is between 20 and 50 ohms – so any reading significantly outside of this range means the element is faulty and needs to be replaced, in this case this element in this video is fine.

What causes heating element to go out in dryer?

If the coil gets too hot, it burns out. Among the conditions that can cause elevated temperatures are insufficient airflow in the element compartment, failure of safety devices and a power surge.

How long does a heating element last in a dryer?

The heating element can last between 8 and 18 years if the dryer is well-maintained and the vent and lint traps are clean. The heating element can burn out if the dryer is not kept well-maintained.

How do you fix a dryer that is not heating?

This is the most common cause of a dryer not heating. To check if your venting is clogged, start a timed dry on high heat. Go to the exhaust vent outside and use your hand to verify that the air is very warm and exiting at a decent flow. If there’s little airflow, your venting likely needs to be cleaned or replaced.

When I press the start button on my dryer nothing happens?

If your dryer won’t start when you push the start button, the most likely causes are a lack of power, a defective door switch, a blown thermal fuse or a bad start switch. If it doesn’t turn on, it’s likely that the dryer has no power. Check your power cord and the house circuit breaker.

How do I know if my thermal fuse is blown?

How to tell if a thermal fuse has blown? To test if your thermal fuse has blown, touch the right side of your multimeter lead to the right side of the fuse, and repeat with the left multimeter lead. If the multimeter needle fails to move, this indicates the thermal fuse has blown.

Why is tumble dryer not heating up?

If your tumble dryer isn’t heating up, it’s likely that the heater may have tripped and needs to be reset. The reset button is usually situated under the back panel of your tumble dryer, which you’ll need to remove by unscrewing it. Sometimes it may be on the back panel, so you won’t need to remove it.

What kind of test to see if the heating element is in good condition?

Use a multimeter to find resistance. If the reading is the same or very close to that of the calculated value, then the element is OK and the fault lies elsewhere. If the reading is a lot higher than the calculated value, the element is failing and won’t be heating fully.
