Dryer heating then tumbler stops after 10min but keeps heating. I have tried cleaning out the lint trap already.

remove the vent duct and remove the object cheers

sounds like perhaps you are losing your heating element...could be electronic, but it's most likely the actual element needs to be replaced...

Instructions

Dryer Does Not Turn On
1

Ensure that the dryer's power supply cord is firmly plugged into an electrical outlet.
2

Inspect the structure's fuse box for a tripped fuse. Each fuse is assigned a single "On/Off" switch. If any fuse switch is in the "Off" position, flip that switch to the "On" position. If the problem persists, contact a professional electrician.

3

Press the "Start/Stop" button on the left side of the dryer's control panel.
4

Close the dryer door firmly so that the door clicks into place. The dryer will not operate if the door is not shut.
Lint Filter
5

Clean the lint filter. Twist the program selector knob on the control panel to the "Off" position, then open the dryer door. Pull the lint filter out of the dryer. The lint filter is located at the front of the dryer's tumbler, and is inserted vertically into the dryer. Gently stroke your hand over the filter to clear the lint, then reinsert the filter and close the door.
6

Turn the dryer off and allow at least 30 minutes for the dryer to cool, as excessive heat can cause a drying program malfunction.
7

Increase the ventilation of the room the dryer is located in, such as by opening a door or window. Excessive heat will cause the dryer to automatically turn off until it cools as a safety measure. Increasing the ventilation will help keep the dryer cool.
Clothing Not Fully Dry
8

Clean the moisture sensor. Open the dryer door to access the moisture sensor. The black-colored sensor consists of two bars, and is located at the front of the dryer's tumbler, to the left of the lint filter. The sensor should be cleaned with a clean cloth and white vinegar once per month.
9

Clean the lint filter. Twist the program selector knob on the control panel to the "Off" position, then open the dryer door. Pull out the lint filter. The lint filter is located at the front of the dryer's tumbler, and is inserted vertically into the dryer. Gently stroke your hand over the filter to clear the lint, then insert the filter back into the dryer and close the door.
10

Spin the laundry at a higher spin speed in the washing machine before placing the laundry into the dryer to reduce the moisture content.
11

Turn the dryer off and allow at least 30 minutes to pass for the dryer to cool, as excessive heat can cause a drying program malfunction.

sounds like the vent tubing is not hooked up as it should be and that can cause a lot of lint buildup inside of the dryer parts. take it apart again and clean out all of the lint because this is a fire hazard. make sure that the vent is connected to the lint trap and try working it again. it sounds like maybe the buildup of lint is making the drying hard to do.

some were he has blocked the out let for lint trap the reason its stopping is its over heating don't use untill sorted it will cause a fire if left

What your seeing is lint that got caught in the vent and over time heat will burn the lint. This is also a sign that you need to clean your lint trap more often

try getting a lint trap brush its long so u can get all the way down in the trap try cleaning that first that is usally the problem

Try cleaning out your Lint Trap, this will be either on the door inside, or inside at the back of the dryer, this should just pull off, remove the built up lint and replace.

did you clean the outside exhaust trap

Heres what you'll need to do.

First pull out your lint trap and place your hand down in the lint trap hole not very far just enough to feel a good amount of air blowing on your hand. If you feel no breeze in there you need to clean the ducting, starting at the back of the dryer (where you hook it up at) and ending out side your house (where vents at). Snake it your self or have someone do it but just the same it has to be done.

Secondly you'll need to change you thermal fuse. If after snaking the dryer still doesn't heat. Changing the thermal fuse is easily done. Firstly you must unplug the dryer and then remove the cover off of the back of the dryer. Then you'll see the thermal fuse
(most of them look like this). Change it and put the dryer cover back on, plug it in and your ready to rock and roll.

Hope this helps
