We have the somewhat popular Kogan/DS 1800W Digital Air Fryer that we've been using daily for about 3 mths now. Just a few days ago a horrendous burning plastic smell started to emit from the unit. Upon opening the door, smoke could be seen emitting from the space around the lower door hinge.
Removed the top cover and found the door micro switch was melted. Not sure if it's due to dodgy design or a faulty switch? The way the switch works is that it switches the live power between 2 circuits, in such a way that when you open the door (to check on food), the fan and heating element turn off, leaving the timer and settings on.
Did a quick google and did not see anyone else with this issue. Just looking at the way it's wired made me wonder if this was a good idea, to have 230v AC from the wall (the top most red wire) directly passing through what looks like a cheap switch image 1 image 2?
