E3 error code - works on heat but not on cool
My cube works on heat but not on cool - it will give the E3 error code.
I ran it for 8 years without cleaning it and there was a considerable amount of gunk inside the reservoir. I ran the cleaning cycle for 24 hours on the highest temperature and the gunk seems to be gone. However if I run it on cool it will get super hot and give out the E3 error code - also it smells very hot and almost like an electrical fire in there. The fan runs on heat but not on cool. Im comfortable opening it up but I don’t know which part to replace, any ideas?
Is dit een goede vraag?
