Guys went out to the above w/dryer this morning machine seemed to be ok but customer saying that aftrer 5 mins the 2nd light from the left as well as the red led is flashing, looked in my trusted book and it points to the air switch but that metered out fine, had a quick look at the heater etc for loose conections but all seemed fine, put it on wash and waited 15 minuites and all seemed fine, so charged a call out and left, 20 minuites later she has phoned and said that its doing exactly the same thing again,
so im asking
1) Is it def going to be the pcb?
2) has anybody come across this before,
Would be gratefull of any help guys
