Start by checking your circuit breakers and ensuring the exhaust vent is completely clear of lint. Most dryers that spin but stay cold have a blown thermal fuse caused by restricted airflow. If the fuse is okay, you likely have a burnt heating element or a failed gas valve solenoid.
Nine out of ten times I show up, the vent's clogged. When that duct's blocked, heat can't escape, temps spike inside the drum, and that little thermal fuse pops for good. Ignore it long enough and you'll cook the heating element too, turning a $10 fix into a $60 one. Clean the vent first, then chase the fuse. That's the order.
OK so here's the deal: your dryer's probably not heating because something in the safety chain broke. Most times it's a $10 thermal fuse, and most of those blow because the vent's packed with lint. Don't just swap the fuse and call it done. Clean the vent first or you'll be right back here in two months. I've literally replaced the same fuse twice on the same machine because nobody cleaned the duct.

Symptoms You May Notice
Clothes come out of a full 60-minute cycle still damp, like they got maybe 10 minutes of actual heat before the machine gave up.
You put your hand in front of the door mid-cycle and feel nothing. Just cool air tumbling out.
The dryer takes two or three hours to dry a single normal load and everything still feels warm-damp at the end.
On a gas dryer you can watch the igniter glow orange through the burner access area but no blue flame ever kicks on, it just glows and fades out over and over.
Auto-dry cycles run forever and never end because the moisture sensor never detects the clothes actually getting dry.
Can you reset a Generic dryer to clear the NO-HEAT-GENERIC code?
There's no single reset button on most dryers. Unplug the unit from the wall for 5 full minutes, then plug back in and run a timed dry cycle on high heat for 20 minutes. If a thermal fuse blew, unplugging won't fix it, you have to replace the fuse. Some dryers have a manual reset button on the high-limit thermostat on the back of the heater housing. Press it with a pen or small flathead screwdriver. If it clicks, it was tripped and that might restore heat.

Frequently Asked Questions
Why does my dryer spin but not get hot?
So here's what's happening. The motor and the heater run on different parts of your electrical circuit. The motor only needs 120V, but the heating element needs the full 240. Sometimes one leg of your breaker trips or the thermal fuse blows, and you end up with a dryer that tumbles just fine but never heats. Blown thermal fuse is probably the most common cause. It's like a one-time circuit breaker that protects against overheating, and once it pops, the heat circuit's permanently open until you replace the fuse. About a $10 part.
Can I bypass a thermal fuse to test the dryer?
Yeah, you can, but don't leave it that way. Jumper the two wires together for 30 seconds to confirm the fuse was the problem. If heat comes on, you've got your answer. Then pull the jumper immediately and order the real fuse. Running without a thermal fuse is genuinely dangerous. If something overheats, there's nothing stopping it, and that's how you get a dryer fire. A new fuse is like $8 on Amazon. Just buy the part.
How do I know if my heating element is burnt out?
Pull it out and look at the coil. You're looking for a gap in the wire, like a snapped guitar string. A lot of the time you can actually see it. If you don't see anything obvious, grab your multimeter and test terminal to terminal. You want to see resistance somewhere between 8 and 50 ohms depending on the brand. No reading at all, or OL, means the coil's snapped. New elements run $20-60 usually, and they're not too bad to install once you've got the panels off.
Why does my gas dryer blow cold air but the igniter glows?
Classic gas valve solenoid failure, and I see this constantly on dryers that are 8-10 years old. The igniter's job is just to get hot enough to open the valve, but the solenoids that actually pull the valve open have worn out. What you'll see is the igniter glows, glows, glows, the coils try to fire the valve, nothing happens, igniter shuts off, tries again a few minutes later. Same cycle over and over. Gas valve solenoid kits are usually $20-40 and it's one of the more satisfying repairs because the machine works perfectly after.
How often should I clean my dryer vent to prevent heating issues?
Minimum once a year. But if you've got a big family doing laundry every single day, every 6 months. And it's not just the lint trap, it's the whole duct run from the back of the machine out to the exterior wall. That's where the real buildup happens. A vent cleaning brush kit is like $15 at the hardware store. I've pulled 15 feet of compressed lint out of people's ducts. Clean vent equals longer element life, faster drying times, and lower electric bills. It's honestly the best maintenance task you can do on any dryer.
What does a dryer thermal fuse cost and is it hard to replace?
The fuse itself is usually $5-15 depending on the brand. Total job with parts and your time is maybe 30-45 minutes if you've never done it before. You pull the back panel, disconnect two wires, unscrew one or two screws, swap the fuse, put it back together. That's pretty much it. The only tricky part is figuring out which panel to remove on your specific model. Look up a YouTube video for your exact make and model number before you start and you'll be fine.
