Installed and furnace fired right up.
Product was packaged and delivered without any issues.
Installation was simple. Replaced an existing control board with code 21, Gas Heating Lockout.
Once installed, heater was turned on at the thermostat and furnace fired up.
HVAC technician was charging $450 for materials and labor. He stated that the board was going for $190.
Thanks for the product and service.
