Completed replacement of 10” and 12” Honeywell supply dampers for 2 zones. I tested function of dampers and then tested at each thermostat. I completed a single system heating maintenance. I replaced 1-16x25x1 filter at furnace filter rack. I cleaned the flame sensor and checked the igniter. I checked the amp draw on the blower motor and capacitor. I checked all safeties and confirmed proper sequence of operation. The system is currently heating at manufacturers specifications.
