What to do if Pure Humidifier ES Humidifier will not fill?
If your Pure Humidifier won't fill, first, check the water supply to ensure there is water pressure. Next, make sure the drain ball valve is closed. If you have an auto drain system, check that the drain valve is closed by removing the actuator and looking at the valve stem position. Finally, check the fill relay to see if it is energized.
Why does Pure Humidifier Humidifier not stop filling or is short cycling?
If your Pure Humidifier Humidifier does not stop filling or is short cycling, several issues could be the cause. Start by checking the fill relay to see if it is energized; if there's no voltage, check for dirt under the valve seat. Also, ensure the drain ball valve is closed. If you have an auto drain system, verify the drain valve is closed by removing the actuator and checking the valve stem position. Clean the probe ends of the Tri-Probe sensor, and ensure the Tri-Probe wiring matches the wiring diagram on the PLC.
How to fix Pure Humidifier ES that will not heat?
If your Pure Humidifier Humidifier will not heat, check and replace any blown main heater fuses. Verify the control transformer is producing 24VAC control voltage by checking the transformer output and verifying voltage across 24VAC Fused & 24VAC Com. Ensure all safety controls are completing the safety circuit. Verify the voltage to and from the humidity sensor, and check/verify the heater voltage and amperage, comparing it to the diagram or nameplate ratings.
