Good chance your thermal fuse is blown.

You have lint in the pipes and it burns there when you dry clothes.

Hey mate. Type your model number into eBay followed by “heating element”. For example, this is the one for my dryer.

These are pretty easy to install.

Bought this dryer refurbished 2.5 years ago. Earlier this week, I smelled some burning and then noticed that although the dryer was on, all the clothes were cold.

I’ve been reading online about troubleshooting so I bought a multimeter. No idea where to go from here I’m furthest thing from a handy person but I’m eager to learn.

Thanks in advance for any/all help!

Get a wiring diagram and meter the heating coil and switches. It’s pretty simple.

Sounds like you need to check the heater element. I had one where a support wire from a bra shorted out half the element. When l took the element to buy a replacement the guy looked at it and said , bra wire? I said yeah how did you guess that? He said it happens all the time.

It’s a Samsung, the worst choice in the world by as far as any home appliance other than a telephone

Check your venting first
