Homebase 641638 1400w 12,000btu portable air conditioner fix repair

I think there are many makes and models of these portable 1400w air conditioners that are all made in the same factory just re branded. Such as haier Danby etc.
I bought this air con unit for cheap because it was faulty and not working correctly. It worked for a few minutes and would then overheat. I didn't film much of it but after a bit troubleshooting and testing I was able to work out the thermal fuse in the exhaust fan had blown which was an easy fix.
