Hello all.I'm trying to fix this hazer, it goes through the cleaning cycle during which it makes some smoke, then the fan starts and no smoke. The LED flashes one time indicating NTC failure. So I obtained a new element from the customer who had one in stock and fitted that, then I got four flashes (indicating over-temperature) but I guess it could also be caused by thermocouple problems? There is hardly any Voltage on the test point at R5. I just want to know what the thermocouple resistance should be when cold? Both of the ones I have read very low, about 1 Ohm, surely this can't be right? Heating the element up with the soldering iron produced no change in resistance.. suspicious! Physically they look OK no breaks or twists in the fine wires. The elements are quite expensive so I don't want to order another one unnecessarily!Dave.
