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

jonathan roger Member

Hello everyone,

I have a Noma 043-5794-8 Dehumidifier showing an E9 fault. After searching the web, it seems to be the humidity sensor. So I would like to know if there are any ways to solve it or bypass the problem. Here are some pictures of the humidity sensor.

Thanks so much!

Did you ever get this? I have the same problem with mine.

Is there a replacement part? Or is it bypassed? In other words, if you remove the sensor, the machine will still work just do not know what the humidity is and thus run 24X7?

Thank you!

Removing the sensor will result in the e9 error. But what I did to circumvent it was soldering the two pins that go into the sensor itself together. This results in the unit believing it to be 88 percent humidity. It got it going. But I have to get a new humidity sensor to replace it so it doesn't run all the time.

Welcome to the forums ….. all.

Add the Noma model number to me.

This board is privately labeled. Very doubtful that it can be traced.

Actually ….. I chased around and found this ….. Humidity Sensor Card

Looks like Hisense can manufacture the Noma unit.
