The Hygrometer on my Air-O-Swiss U7142 reads 25% all the time. I assume its not functioning properly as I have other hygrometers in the house which say higher readings. Is there a known way to fix this? I...
I have got the same problem with my u7142 unit. This most probably means that the hygrostat inside is either broken or it has been heavily covered with the "white dust" in case the demineralization cartridge has not been changed for a long while.
To resolve it you have two options: either clean the humidity sensor or replace it. The sensor is at the bottom of the front panel, so you need to disassemble the front panel only, no need to open the whole unit (note that there are 2 screws at the bottom holding the front panel also). You need to get the sensor out from the printed circuit to open the cover and clean the surface of the sensor with something (blowing air does not help; you need physically touch the surface with something). If it does not help then you can go for the second option to replace the sensor, the type used in the unit is SYH-1. It is not a pricy element so you may go straight to the replacement if you find a shop nearby to buy it. I have simply replaced the sensor and now the unit is showing the proper humidity value and adjusting the steam automatically again.
