My humidifier control have on digital display E3 what that mean

Check Filter Indicator The ability of any humidifier to efficiently supply humidity output relies heavily on the condition of the filter. As the filter loads with impurities it gradually loses its wicking capability. When this happens, moisture output is reduced and the humidifier has to work longer to satisfy the selected setting. This humidifier has a check filter reminder timed to appear after 720 hours of operation. When the Check Filter (CF) message is displayed, disconnect the power cord and check the condition of the filter. If a build-up of deposits or severe discoloration is evident replace the filter to restore maximum efficiency. The CF message is reset when the humidifier is plugged back in.

E3 indicates a sensor fail - most probably the humidity sesnsor. Or it could be a fault in the display itself. Are all the functions working properly?

If your humidifier is equipped with a Digital Humidifier Control with Water

Panel change indicator, after replacing the Water Panel, turn the control

knob to the "Test/Reset" position until the "Humidifier On" light blinks to

reset its timer. (Blower must be operating and HVAC calling for heat.) Be sure

to turn the control knob back to it's original setting. If the "Humidifier On"

light continues to blink, your humidifier is in Test mode. DO NOT LEAVE THE
CONTROL IN TEST MODE OR HUMIDIFIER WILL NOT OPERATE.

It means Change Filter.

However, assuming that you have done that in the recent past, you probably want to know more. I'm not sure how this actually works (that is why it shows CF). I saw it for the first time after 2 or 3 years of using my humidifier. (And I had just changed the filter a week or so previously).

You may have to turn the unit off/on or even unplug it to clear the message, then it should operate normally.

Thank you for contacting us with regards to your model 600 Humidifier. The Change Water Panel indicator should flash when the control knob is set to the Test/Reset mode. The flashing indicates that the timer has been successfully reset. However, the humidifier should operate for the first 60 seconds of Test mode as long as your furnace is running. If your humidifier does not turn on, contact your installer. The humidifier may require service.
We appreciate the opportunity to be of assistance.
Sincerely,

It means replace the batteries in the thermostat.

i believe e3 is an outdoor sensor problem, most people use manual mode, you should see a blue jumper that is connected to 2 OD terminals at the control, or if u use a sensor there should be a wire run outdoors, if you dont have the manual mode part you have to get it from an aprilaire dealer, cant just jump it out, it is a resistor

I have the same type of Aprilaire humidifier unit with automatic temperature sensing control. My unit also displayed the 'E3' code. The HVAC technician was on site today and replaced the temperature sensing unit that is located outside the house. The humidifier is functioning normally once again.
