Original Post: How can I fix humidity sensor on a Noma dehumidifier?

jonathan roger - Member

Hi everybody,

I have a Noma 043-5794-8 Dehumidifier who shows a E9 error. After searching on the web it seems to be the humidity sensor. So I would like to know if there is any ways to fix it up or bypass this issue. Here are some pictures of the humidity sensor.

Thank you very much!

Did you ever get this figured out? I have the same issue with mine.

Is there a replacement part? Or is it bypassable? In other words, if you take the sensor off will the machine still work just won't know what the humidity is and thus run 24X7?

Removing the sensor will result in the e9 error. However what I did to bypass it was solder the two pins that go into the actual sensor together. This results in the unit thinking it it's 88 percent humidity. That got it going. But I’ll need to get a new humidity sensor to replace it so it doesn’t run all the time.

Welcome to the forums..... everyone.

Post the Noma model number for me.

That board is private branded. Very doubtful it can be traced.

Actually..... I was hunting around and found this..... Humidity sensor board

Looks like Hisense may manufacture the Noma unit.
