Home Improvement Questions? Ask a Handyman for Answers
Hello… my name is ***** ***** I will be assisting you today. With your help, hopefully we can find a quick and correct solution that will answer your specific question. Is there any additional information you would like to add that was not mentioned before?
I'm sorry it took so long however your post just came up when I responded, perhaps another expert had it locked up, I would like to help answer your question if you want me to try?
do you happen to know which mode it is in?
three possible modes: motion on/motion off, motion on/humidity off or humidity on/humidity off.
The humidity sensor is adjustable between 30% and 80% RH and factory set for 50%.
The humidity sensor continues to check that the moisture levels conditions have been met.A built-in humidity sensor - detects rapid rise in relative humidity (RH), automatically turning on the fan to remove moisture and helping to prevent mold and mildew.
Built-in adjustable delay timer - can be set from 30 seconds to 60 minutes and activates when motion is no longer detected or when humidity levels are below preset levels
The fan can be set to run 0.5 to 60 minutes after the motion sensor ceases detection or the humidity returns to the set point
Built-in SmartAction® motion sensor - automatically turns on when you enter the room.
if I had to make a judgement call I would say the humidity sensor is either working properly (because the relative humidity is above what it is sensing regardless of the setting selected) or the humidity senor is not working properly (because the selector or the sensor itself is not working)
you can isolate the problem by simply bypassing the humidity sensor and see if the fan stops when you adjust the setting level.
everywhere I looked replacement parts for the sensors are not available (at $180 it's easy to see why), you can bypass it simply by jumping the wires (it's a switch so connect the wires together bypassing the sensor)
If it was me doing this job, I would not be spending a lot of time on it trying to figure out something that is most likely not repairable. I would buy a new one and move on to something else less frustrating, but that's just me.
of course there is the possibility that the RH (relative humidity) is excessive and the fan is doing what it was designed to do. Changing out the unit will confirm either a bad unit (old fan) or excessive RH
would hate to think you got someone else's headache
they have a support section where you can enter the model number and go from there
since there isn't any replacement parts available locally (maybe Panasonic Support can ship a replacement) I don't think I can help you much more than this
I again apologize for the issues you had with getting your question answered in a timely manner and I hope you find a quick solution knowing what you have to work with.
