Dryer Not Heating? How to Troubleshoot Before Calling the Pros

You know that sinking feeling when you toss a load of wet towels into the dryer, hit start, and come back an hour later to find them still damp and cold? Yeah, we’ve all been there. The drum’s spinning, the timer’s counting down, but the heat? Nowhere to be found.

Before you panic and start Googling new dryers (or resign yourself to hanging clothes all over your apartment), take a breath. Most of the time, a dryer that won’t heat is actually a pretty simple fix. Here at Evo Appliance Repair, we see this issue constantly—and honestly, sometimes it’s something you can knock out yourself in under 30 minutes.

Let’s walk through what usually goes wrong, starting with the easy stuff and working our way up to when you should probably call us at (604) 200-3054.

Start With the Obvious: Is It Actually Getting Power?

I know, I know—sounds almost insulting, right? But you’d be shocked how many service calls we roll up to where the fix is something embarrassingly simple. Dryers need a surprising amount of juice to heat up, and if something’s wonky with your power, you’ll get a spinning drum with zero warmth.

Check your breaker first. Dryers run on 240-volt circuits with two breakers ganged together. Here’s the thing—one can trip while the other stays on. You get enough power to spin, but not enough to fire up the heating element. Flip both breakers fully off, then back on.

Test the outlet if you’re comfortable. A multimeter will tell you if you’re actually getting 240 volts. If you’re reading 120 or zero on one leg, that’s your culprit—and honestly, that’s an electrician problem, not a dryer problem.

The Lint Trap: Your Dryer’s Worst Enemy

Here’s a stat that’ll make you gulp: clogged lint traps and vents cause about 2,900 home fires every year in the US alone. And they’re also the #1 reason dryers stop heating.

When your dryer can’t vent hot air properly, it actually overheats. Modern dryers have safety thermostats that shut down the heating element when things get too hot. Smart feature—prevents fires—but it also means your clothes stay wet.

Pull out that lint trap and really clean it. Not just a quick swipe—wash it with warm soapy water every few months. Fabric softener residue creates an invisible film that blocks airflow even when the trap looks clean.

Check your vent line. Go outside and find your dryer vent (usually a 4-inch hood on an exterior wall). When the dryer’s running, you should feel strong, warm airflow. Weak or barely there? You’ve got a blockage. Detach the vent from the back and clean it out—or call a pro if it runs through walls.

The Thermal Fuse: A Common Culprit in Vancouver

This little guy is basically a safety switch that blows when your dryer overheats. Once it trips, the dryer spins but won’t heat—exactly what we’re dealing with.

The frustrating part? Thermal fuses are one-time-use. Once they blow, you need a new one. They’re also pretty sensitive, which means a partially clogged vent (see above) can kill them fast.

Testing it is pretty straightforward if you’re handy. Unplug the dryer, find the thermal fuse (usually on the blower housing or near the heating element), and check for continuity with a multimeter. No continuity means it’s dead.

Vancouver-specific note: Our damp coastal climate means dryers work harder here than in drier places. Combine that with all the pet hair from our outdoor-loving furry friends, and thermal fuses blow more often than you’d expect. Keep those vents clean!

Heating Elements: When They Burn Out

Electric dryers use a heating element that looks kind of like a giant toaster coil. Over time, these burn out or break—usually after 8-15 years, depending on how hard you run your dryer.

Signs it’s failing: Your dryer takes longer and longer to dry clothes, then eventually stops heating completely. Sometimes you’ll spot visible breaks in the coil if you pop off the back panel.

Replacing a heating element isn’t rocket science, but it involves disassembling parts of your dryer and working with 240-volt electricity. If you’re not 100% confident, call a pro. The part runs $30-80, labor adds another $100-200 depending on your model.

Gas Dryers: Different Problems

Got a gas dryer? The troubleshooting changes. Instead of a heating element, you’ve got an igniter and gas valve coils.

The igniter glows red hot and ignites the gas. Cracked or burned out? No heat. You can usually see it glowing through a small inspection window when the dryer starts—if it doesn’t glow, that’s probably your issue.

Gas valve coils are another common failure. These electromagnetic coils open the gas valve when energized. They can fail intermittently at first (works sometimes, doesn’t others), then completely. They’re cheap ($10-20) and relatively easy to swap.

Important: If you smell gas at any point, stop immediately. Turn off the gas, open windows, leave the house, and call your gas company. Don’t mess with gas leaks.

When to Call Evo Appliance Repair

Look, we love a good DIY success story. If you fixed your dryer with a vent cleaning or a $15 thermal fuse, that’s awesome—seriously, high five.

But here’s when you should probably pick up the phone and call (604) 200-3054:

• You’ve checked the obvious stuff (breaker, lint trap, vent) and everything looks fine
• You’re dealing with 240V electricity or gas and you’re not totally confident
• The dryer is making weird noises, smells like burning, or showing error codes
• You replaced a part but the problem keeps coming back
• Your dryer is under 5 years old (might still be under warranty)

We’re local to Vancouver—we get the unique challenges of appliances in our damp climate. We service everything from basic GE and Whirlpool to high-end Miele and Bosch. And unlike the big national chains, we actually answer our phones and show up when we say we will.

Prevention Tips

A little maintenance goes a long way:

1. Clean the lint trap after every load. Takes 5 seconds, prevents 90% of heating issues.
2. Clean your vent line annually. DIY or hire a service—crucial for performance and safety.
3. Don’t overload. Cramming clothes strains the motor and blocks airflow.
4. Give your dryer breathing room. Keep a few inches behind it—never push it flush against the wall if it crushes the vent hose.
5. Listen to it. Taking longer to dry? Making new noises? Running hotter? Investigate before it gets worse.

FAQs

How much does it cost to fix a dryer that won’t heat?

Depends on the issue. Clogged vent cleaning might be free if you DIY. Thermal fuse replacement is usually $150-200 including the service call. Heating element or control board can run $200-400. We always give upfront quotes before starting any work.

Is it worth repairing a 10-year-old dryer?

Generally yes—if the repair is under $300. Dryers are simple appliances that last 15-20 years. But if you’re facing multiple expensive repairs or your dryer is eating energy because it’s running inefficiently, replacement might make more sense.

Can I use my dryer while waiting for repair if it’s not heating?

Technically yes, but we don’t recommend it. Running without heat strains the motor and wastes electricity. Plus, damp clothes sitting in a warm drum get musty fast.

Why does my dryer heat sometimes but not always?

Intermittent heating usually points to failing gas valve coils (on gas dryers) or a dying heating element making partial contact. Could also be a control board issue. Worth diagnosing properly since it’ll only get worse.
