Question about Dryers
Hello and welcome to Fixya,
The problem you`re having ( based on your description, checked exhaust/vent duct`s...hi limit tripping...suspect it faulty ) can be provoked by several factors with dryers, but specifically when it comes to asko in this case.
I`ll try to explain the most common and therefore most likely cause or causes following a couple of questions to clarify where you are in the diagnosis process and what you`ve tried.
First...when you reply can you specify the actual model you have, i.e. TD73, T700, etc. ( Likely the TD73 series based on it`s age, but better sure then guessing ).
Since you`ve stated you checked the vents and lint screen, I`ll ask this. Have you tried running a cycle with the exhaust to the outside disconnected ?
If not try it and see what happens, does it still trip the hi-limit ?
If no it doesn`t trip, then you have a venting problem/air-flo restriction somewhere between the dryer and outside.
If yes it`s either a heating element ( asko original part #8063808 ) or blower wheel/impeller ( asko original part #8055200 ).
Both heater & impeller can also be completely clogged with lint causing the hi-limt to trip as opposed to being outright faulty.
Let me know how this goes and I can assist you further in guiding you to access and inspect the heater and impeller based on the answer`s you post back...if you think you`re capable or you may decide to just phone a technician.
In the event you phone a tech. I`ll add this, make certain the tech. is from an authorized asko service provider or potentially you can spend a lot of money in uneccessary repairs and parts.

Remove the lint filter and wash it with white wine vinegar and a brush (Old tooth brush or dish scrubber). Then wash it with soap and water. Lint filters over time collect the fabric softener fabric sheets or the liquid used in the washer particulate and can appear clean but actually be completely clogged.
Also look deep into the lint filter passages for signs of lint build up. Use a crevice tool and a folded metal coat hanger to remove the old lint. Then go outside and clear the through the wall vent flapper assy on both sides of the metal flapper.
What your describing it poor air flow. The high limit thermostat is working fine as it is shutting down the dryer when it gets hot. You really do have an air flow problem.
The last thing that can cause this is the blower wheel assy that is attached to the motor. If the venter hub has failed or is loose it will not turn fast enough to produce the proper airflow.
If after all ove the above cleaning the problem persists, disconnected the ducting from the back of the dryer and see if it runs normally. If it does then the problem is in the ducting external to the dryer.
So in summation... you either still have clogged ducting / lint filter or.... the blower wheel has failed.
Thanks for using FixYa.
