Heating system check and service. Humidifier was not running because of installation error in the low voltage wiring. Corrected and now running, HOWEVER, the humidifier will continue to operate ineffectively and may even start leaking due to the location of where/how it’s mounted. Recommended installing on the supply side of the system. System is 2 years old, average life is 10-15 years. Continue routine maintenance for prolonged life.
