Tumble Dryer Problems – How to Spot and Fix Common Issues

If your dryer is acting up, you’re not alone. Most homes face at least one dryer hiccup a year – a noisy drum, a cold load, or a machine that just won’t spin. The good news? Many of these problems have simple fixes you can try before calling a pro. Below we break down the most frequent issues and what you can do right now.

Why Your Dryer Won’t Heat

A cold dryer is frustrating, but the cause is usually easy to find. First, check the lint filter – a clogged filter restricts airflow and can trigger the heating safety switch. Give it a quick clean and run a short cycle. If the dryer still stays cool, look at the power supply. Electric dryers need a 240‑volt outlet; a tripped breaker or a loose plug will cut the heat. Reset the breaker or reseat the plug, then test again.

When power and lint aren’t the issue, the heating element or thermal fuse is likely to blame. The element can burn out after years of use, and the thermal fuse will cut power if the dryer overheats. Both parts are inexpensive and replaceable with a screwdriver and a multimeter. If you’re comfortable unscrewing the back panel, check for a broken coil or a blown fuse and swap it out.

When the Drum Won’t Turn

A drum that won’t spin usually points to a broken belt or a faulty motor. Start by unplugging the dryer and removing the front panel – you’ll see a rubber belt wrapped around a small drum and the motor pulley. If the belt looks frayed or snapped, replace it; it’s a common wear‑and‑tear problem.

If the belt looks fine, the motor may be stuck. Give the motor a gentle spin by hand; it should turn freely. A gritty or stiff feel means the motor bearings need lubrication or the motor itself might need replacement. While you’re inside, also check the idler pulley – a worn pulley can cause the belt to slip and stop the drum.

Other issues like a noisy dryer often come from a loose drum support roller or a worn drum bearing. These parts create that rattling sound you hear during the spin cycle. Tightening the screws or swapping out the rollers can silence the noise and keep the drum balanced.

Don’t forget to clean the vent hose regularly. A blocked vent makes the dryer work harder, leading to overheating, longer drying times, and even fire risk. Pull the hose away from the back of the dryer, clear any lint, and reattach it securely.

If you’ve tried all the DIY steps and the dryer still misbehaves, it’s time to call a qualified technician. A professional can test internal sensors, diagnose electronic control board faults, and ensure the repair meets safety standards. Trying to fix complex electrical parts yourself can be dangerous.

Regular maintenance can keep many problems at bay. Clean the lint filter after every load, vacuum the vent hose monthly, and give the drum and belts a quick visual check every few months. A little routine care saves you time, money, and the headache of a broken dryer.

Remember, most tumble dryer problems start small. Catching a clogged filter or a loose belt early prevents bigger breakdowns later. Use the tips above the next time your dryer acts up, and you’ll likely get it humming again without a hefty repair bill.
