Note:- The front NTC connects on the top edge of the circuit board - plug with two orange wires. The element and rear NTC are connected on the right hand side of the circuit board - this plug has 5 wires Blue, Orange, Brown, Red and Black.
1) The front NTC measures approx 500k ohms.
2) The rear NTC measures approx 500K ohms [red and black wires on the plug]
3) The resistance between Orange and Blue Wires is Approx 46 Ohms [This is one half of the element]
4) The resistance between Orange and Brown wires is Approx 46 Ohms [This is the other half of the element]
5) The resistance between the Blue and Brown Wires is approx 92 Ohms [This both parts of the element]
My machine has 2 devices above the element, one is an NTC the other is the safety cut-out. The safety cut-out is connected in the orange wire to the element common connection.
The resistance of the NTC's varies with temperature - so you may not get the figure I have quoted. The resistance reduces as the NTC warms up; if you remove the NTC connect it to an Ohm meter and warm the flat metal side with your finger you'll see the resistance go down - the drop wont be dramatic [after all your finger is not that hot] and is easier to see on a digital meter.
Measurements taken with the plugs disconnected on a digital meter... and don't forget folks MAINS PLUG OUT FIRST!!!!
Important.... there are some different versions of these dryers, so different readings may be obtained.
