Gas dryer runs but no heat. Took it apart cleaned all ducts and lots of years worth of dirt out of entire machine, looks brand new. Tested all components.

Probably not. dryer no heat, first check the thermal fuse, then the ignitor. If the heating is intermittent, check the gas solenoid coils. In any case, be sure the entire exhaust duct is clean

Small 3oo f fuse mounted on the heater element is probo blown from over heat due to vent blockage.

Had the same problem. There was a bit of a kink in the vent duct which caused lint to build up in duct and also inside the dryer itself over years. I replaced the duct and took dryer apart and cleaned out the air passages.It works great now. As for the humming, mine started about 2 1/2 years ago and I still don't know why.

if you have heat in the dryer you have a blockage somewhere in the dryer or the vent line,how long is the vent line?also try removing the vent line from the back of the dryer and run it to see if it dries,i had a guy tell me he cleaned the vent line,i stuck a leaf blower in the vent line and blew out a birds nest.also check the outside duct,if there's a cage or screen on it remove it and keep it off and then blow out the line. also the duct that the lint filter slides into should be removed and cleaned.send the model number so i can look up your machine,if it's gas you could have bad gas coils,they work fine until they heat up like 15 to 30 minutes then no heat until they cool down and then they will work for a few minutes and stop again,send model number off of the dryer,open the door and look around the opening,you should see a tag with the model and serial number.

Your duct fuse looks like this:
The white skinny fuse will blow if junk is inside the filter housing

Right below that fuse is the control. It maintains the temps inside the drum



I have a manual and more HERE

Sounds like a faulty high limit or cycling thermostat. The thermostat tells the dryer to heat until the interior of the dryer reaches a certain temp. It should be mounted on the exhause duct inside the back of the dryer. It should look something like the one in the picture:



Hope this helped and best wishes.

Hi, It sounds like the coils on top the gas valve are bad. If the ignitor glows but shuts off before a flame, the coils need changed.
I hope this helps. If I can assist you further, please let me know.

Thanks

hi look for the thermal fuse at the back where you cleaned . its a small plastic piece with 2 small blue wires . replace this part thanks

We have the same problem as posted above (dryer not heating up) only we have a Kenmore gas dryer Model 76702693. What should we do? Please help. Thanks.

Hello. I was the last person to post with problems with the Miele T1403 Electric dryer. Just wanted everyone to know I solved my problem and this could solve yours as well. To reiterate I too was frustrated with clothes that would not dry. I could feel heat but the vent/filter light would keep beeping and evetually turn off my dryer. The result would be damp clothes especially towels!! I had a certified Miele dealer come in and check out the machine. This was after I completely cleaned out the lint trap the inside of the machine, and the duct connecting it to the wall. Well they looked at everything and determined nothing was wrong with dryer and I had done a great job cleaning it. Armed with this info I was referred to a company that specializes in cleaning the entire interior duct system of the dryer(Not just the lint trap, inside of machine, and connector tubing). They came today and disconnected the machine again went into the attic and used a shopvac type of machine to really clean the entire duct system. Not rocket science but viola problem solved!! You could probably do this yourself if you have a shopvac with a long attachment (depending on how many bends your system has). The machine is working great and now I know to clean the system at least once or twice a year. I was told that slow drying clothes, extra moisture, machines that are very hot to the touch,etc. can all be symptoms of a blocked vent. By the way a blockage can be a fire hazard. This solution is a lot cheaper than a service call or worse getting a new dryer. I wouldn't listen to the hype about European dryers like Miele or Bosch not drying clothes all the way-could just be a blockage. These brands are very good at shutting themselves off when they get hot (which is a good thing).
