Have you had a look at the heater coils themselves to see if they have blown?
Also do you have a multimeter?
If so then you need to test the continuity through the heater and see if it faulty.
Ok check them and also test for continuity across the heater coils as well to make sure that's fine and let me know what you find.
If you can send a picture that would be great.
If you look at the tool bar above were you write you should see a picture of a paper clip. Click on there to attach files and picture.
We are not allowed to post email addresses on here im afraid. They will get crossed out by the system.
But you can upload them to a file shareing site like this www.mediafire.com and post me the link then I can access it.
You can try and email to customer services. Contact them from you account page and email it them and then they can pass it over to me.
But ive searched the parts list and have seen what kind of heater is on there.
The thermostat with a red button is the reset thermostat.
Then theres a thermistor near this it will have 2 black wires going to it. This will give a Kohms reading on your meter. Usually these are about 20 Kohms.
So looking at the heater do you have 5 wires?
2 black wires are the thermistor so the other 3 wires should have continuity between all 3. Check that and see what you find and let me know.
Strange as there must be a problem on the site as usually you can upload pictures.
But as to the heater from the readings you are getting the heater is fine.
There is another sensor on this. If you remove the plastic cover on the front at the bottom on the right is the NTC sensor. It will have 2 thin wires going to it. Check this for resistance. Again this will be about 20 Kohms.
If that's all ok then all thats left is the control board at the top. Take it off and see if theres any signs or burning on there.
But if the heater and front NTC are fine then its looking like the control board may be the fault here.
You need to remove the plastic control panel.
Take the top off and look at the panel and you will see the screws holding it on and the tabs.
Once you have that panel off you will be able to remove the board from there.
Have you removed the plastic cover on the front at the bottom?
Take the condenser out and you should be able to remove it from there.
The NTC sensor is at the bottom. You need to remove the plastic trim at the very bottom of the dryer on the front and then you can access the NTC sensor.
Try that and see what you find.
Ok if you cannot see it then it may be behind the front panel.
Im not extactly sure as I don't have the service manual in front of me on this model. But on others once you remove the plastic cover at the bottom its there on the right.
So looking at the parts diagram it may be behind the front panel.
I will opt out of this now and if another expert can help you better they will jump in. If you no one sorted it or its faulty I will see if I can get the service manual and jump back in.
Just hang on and if someone can help they will jump in.
Please don't reply back to me as it just locks the question to me and the other experts wont see the question.
Sometimes giving answers online without seeing the appliance can be very hard. We don't want to tell you to replace something that you don't need to.
Sometimes we do get questions were you need to have an hands on engineer to check it out. sorry but if no has replyed then you may be best getting it checked out .
To be honest with you from what you say the heater sounds ok so the fault lies with either the NTC sensor or the control board im afraid.
I did check to see if I had the service manual for this but I didn't sorry.
