Hello....

I have an issue with my LG RC9011A Tumble Dryer.
Some times it works, most of the times it doesn't and doesn't heat up at all.
It gives a TE3 Error message on the display after 5 minutes.
On the LG website it says this:

'TE1' error code - Heating Error - Low temperature thermistor open circuit
'TE2' error code - Heating Error - Low temperature thermistor short circuit
'TE3' error code - Heating Error - High temperature thermistor open circuit
'TE4' error code - Heating Error - High temperature thermistor short circuit

Does this mean that there is something disconnected within the dryer?
I already tried opening it and reset the thermistor but that didn't solve the problem.
I made the conclusion that it's not completely broken, because sometimes it does it up and works.

What part of the dryer is broken?
Can I fix it myself?
I fix laptops and mobile phones for a living so I am quite handy.
Any pointers or hints?

Thanks a lot!
