Thread semi hi-jack. I've got a similar problem, but my dryer gets hot. My dryer will dry the clothes, it just takes a lot longer than it used to. I've checked to make sure the exhaust hose wasn't kinked, removed the back panel and cleaned out the exhaust tube in the dryer itself, lint trap, etc. There's plenty of air coming out of the exhaust outside.
Its warm in the dryer when you open the door while its running. Its an electric dryer. Are their multiple elements and one could be out? Is the heat cycling off and on for some reason? Scratching my head on what could be going on. Any help would be appreciated.

Napoleon, slight hijack (but it IS about dryers)...

My dryer vents directly behind my two A/C condensers. Can I throw a 90 on there and run it out about 10 feet or so? Or would that restrict the airflow of the dryer?

Heating element. Easy to change.

If it's an electric dryer and the thermal fuse pops then the motor wouldn't come on. The blue wire runs to the motor on electric.
If gas then the heating wouldn't come on as the blue wire runs to the igniter in a gas dryer.

Now if it's the high temp cut off then yes the motor would run as the thermals cut direct heating power.
The thermal fuse though does things differently depending on the voltage design of the machine.

The thermals use bi-metal fuses and are on the part that heats up. The thermal fuse, thermostat and thermistor(if applicable) are all on the exhaust.
A thermal fuse trips when the exhaust temp is too high, the high limit thermal trips if the heating temp gets too high, usually in conjuction with the failure on of the thermal cut off. The cut off being the bimetal device that cuts heating power when operating temp is reached and cuts back on after a drop of 45°.


The thermal fuse is the number one cause of this issue in gas dryers. The thermal high limit or the element is the cause on most electric units

I don't mean to demean the OP if this is the cause, but I'm always surprised at how many people just don't realize that you have to do basic stuff like this to keep your stuff running correctly


Basic maintenance and common sense. Sometimes you have to approach things like every smarmy IT guy you've ever dealt with; "Is the computer plugged in? Is it powered on?" They ask these questions because people will neglect to check if the computer is in fact plugged in and powered on.

That would reduce the dryers efficiency but it should still work

Ours went out on a new dryer and you had to practically disassemble the the entire machine.

Change your thermostat and thermals.

Usually you can get all three in a package deal.

A bad thermostat will cause that issue.

Or just use timed dry all the time

Also. Do the dollar bill test.
With the dryer door open. Hold the switch and start the dryer on a no heat cycle.
Place a dollar near the air vent(outlet not the one heat comes in from) it should suck hard to the vent. If it doesn't you have an airflow issue.

I get maybe three calls a week that go like this...

"My machine isnt working at all, no buttons work, nothing"
--are there any lights on, any codes?

"Yes the light next to child lock is on"

--yes, hold that button until it comes off.


I also love people who put their fridges into "sabbath" mode. Where the fridge works, just no switches work including lights and ice because Jewish people can't use switches on Saturdays.
They didn't even believe it's such a thing when I dumb out down like that. Lol

Gotcha. I had this same problem several years ago and I had an electric dryer. I know it was a fuse that was the issue, so I guess it wasn't the thermal fuse. I do know that the repair guy I called was gonna charge me $125 to come out and diagnose. I decided to DIY a little first and the fuse ended up costing me $11 including expedited shipping.

Take a blower and blow out the vent. I’d be willing to bet lint clogging up the vent is the problem.

I learned that lesson a long time ago when dealing with my mom. She rearranged her living room, and called me to help her because her dvd player wasn't working. I went through all the steps with her over the phone, and couldn't figure out why it wasn't working.

I drove all the way to her house to find that she didn't plug the dvd player in when she moved it. So, now whenever she calls me about something not working my first question is "Is it plugged in? Is it powered on?"

See I hate generic answers. SOME heating elements are easy. Nine screws and one or two panels and voila. Some require the full tear down of the machine and the removal of everything except the motor.


Well mine requires a full tear down and it still takes me less than 30 minutes. Top comes up, front comes off, lint catch comes out, drum comes out, and there is access to everything else.

It's a dryer, not a rocket ship.
