Was easy to install; solved the problem with the humidifier. However, the humidifier should have a separate error LED for the heater and the water valve. Since it does not, be sure to check the heating element with an ohm meter to determine if the elemnt is defective before placing your order. No continuity thru the element the element is defective.
