How do you test a humidifier solenoid with a multimeter?

Turn the humidistat to a very high setting, such as 80% relative humidity, or until you hear a “click” sound. The multimeter should register about 24 volts. If you show 24 volts at the connection from the humidistat to the solenoid, then the humidistat is operating correctly.

Also, how many ohms should a solenoid have?

Generally, most solenoids measure between 20 and 60 ohms of resistance.

Likewise, how long do humidifier solenoids last? We have hard water and so we find that we have to replace them about every 5 years. If you have a water softener, the solenoids might last longer. Bottom line: We would recommend this solenoid as a good replacement part for the Honeywell Enviracare Elite HE265A Bypass Whole-House Humidifier.

Likewise, people ask, should a solenoid have continuity?

Yes, with the solenoid disconnected, you should have continuity between the small, COIL terminals. The small terminals are connected to the coil which activates (connects) the large, PRIMARY terminals of the solenoid.

How can you tell if your solenoid is bad?

Solenoid Valve fails to open. Check if valve is normally closed (power to open) Or Normally Open (Power to close) Use magnetic detector lift coil slightly to check if magnetic field is present.Do not remove coil if energised as IT WILL BURN OUT Check contacts Check wire connections and DIN connector. Check fuses.
