Heats for about 5 mins then displays ‘clean out airways’.
All filters are clean and the condenser is clear of blockages.
The NTC on the top of the heater measured about 150K ohms ambient. Looking on Connect at available parts, it seems there is an other NTC but I didn’t locate this during my visit.
There’s another one at the front.You have to take the front off.take out the five screws around the drum entrance,then there’s two more, one at each bottom corner.You’ll then see the ntc,neatly concealed in a rubber holder.hope this helps!
