I want to first make sure that your dryer is serviced up. so i want you to do these steps.
Most of the problems will be resolved doing these......
As clothes are tumble dried, they drop fibres. Most of this fluff is
trapped by the lint filter and this needs to be checked and cleaned
regularly. Lint also builds up in the vent pipe and around the electric
motor in the rear of the dryer.
1.clean lint filter
Wait until the dryer cools, open the door and lift out the lint filter.
Gently brush off lint using your fingers.
On many models, the filter may also be washed. Check your manual for instructions.
If the filter is damaged in any way, you should replace it.
2.Vacuum area where lint filter sits:
The area where the lint filter sits should be vacuumed .
Remove the lint filter, and use a narrow vacuum nozzle to remove dust and lint from the fitting.
3.Clean inside the tumble dryer:
1. Make sure the dryer is cool, switch it off and unplug it.
2. Unscrew the retaining screws on the back panel, and lift it off. Vacuum the blower area.
3. Also vacuum around the vent pipe connection.
4. Replace the back panel and refit all the screws.
4.Check tumble dryer vent hose:
Wait for the dryer to cool. Unplug the vent hose and inspect its entire length for snags in the pipe.
Make sure the vent is not obstructed on the outside wall, and fit a flap or screen to keep out small animals.
If your vent pipe is punctured or damaged, you should replace it.
To avoid dryer problems,
Make sure the dryer is level and does not rock, and consult the
manufacturer's instructions for the maximum weight of clothing to dry
at one time. Also, make sure clothes have been spun-dry before putting
them into the dryer.
This is just initial help,
Post your comments about how things turned up, Ill be giving suggestions based on your reply........
