Why won't my Neptronic Humidifier drain and the CHECK light is on?
If your Neptronic Humidifier will not drain and the CHECK light is on, verify the drain valve, the fill and drain water pipe connection, and the water level sensor chamber are not obstructed. During a Drain or Foaming cycle, the water level sensor may have sensed the water level has not decreased. Reset the Alarm.
Why is my Neptronic Humidifier not producing steam?
If your Neptronic Humidifier isn't producing steam, check the interlock switch. Also, verify the wires to the control terminal blocks #F & 5 are properly secured.
What to do if my Neptronic Humidifier is not producing steam?
If your Neptronic Humidifier isn't producing steam, check the fan operation. The issue may be that air flow is not detected by the air pressure switch. Also, verify the wires to the control terminal blocks #F & 2 are properly secured.
How to fix a Neptronic Humidifier that is not producing steam?
If your Neptronic Humidifier isn't producing steam, check the operation of the high limit humidistat. The issue may be that the high limit humidistat is open. Also, verify the wires to the control terminal blocks #F & 1 are properly secured.
What to do if my Neptronic Humidifier does not drain and the CHECK light is ON?
If your Neptronic Humidifier is not draining and the CHECK light is on, it indicates that during a Drain or Foaming cycle, the water level sensor has sensed that the water level has not decreased. Verify that the drain pump, the fill and drain water pipe connection, and the water level sensor chamber are not obstructed.
Neptronic Humidifier CHECK light on and not operating, why?
If your Neptronic Humidifier is not operating and the CHECK light is on, verify the water level sensor and water level chamber and clean if necessary. The time elapse between two refills may be too long when the humidifier is producing steam. Reset the Alarm.
How do I fix Neptronic Humidifier with CHECK light on?
If your Neptronic Humidifier is not operating and the CHECK light is on, verify the internal wirings and connections. The internal 24vac of the humidifier may be shorted. Replace the fuse.
Why is my Neptronic Humidifier not working with CHECK light on?
If your Neptronic Humidifier is not operating and the CHECK light is on, check the external wirings. The external 24vac provided to the humidifier may be shorted.
How to fix Neptronic Humidifier when CHECK light is on?
If your Neptronic Humidifier is not operating and the CHECK light is on, verify if the humidifier was operating below the standard water level. The electronic temperature sensor inside the water level sensor may have sensed abnormal temperature. If necessary, replace item J.
How to troubleshoot a Neptronic Humidifier that won't turn on?
If your Neptronic Humidifier isn't powering on, first, ensure it's receiving main power and check the fuses. Also, inspect the wire harnesses inside the humidifier and the main PC board to confirm they are properly secured.
