Perform the maintenance for the gas furnace, replace the customer supplied air filter. Installed a new inline water filter for the humidifier, cleaned out the water tray and confirmed operation of the humidifier. I need to return with a replacement pad. Start up the furnace and check the operation, confirmed operation of the gas valve and of the safety controls. Checked all plugs and electrical connections on the circuit board, and confirmed proper operation in ramping up and down of the blower motor and draft inducer. The furnace is operating properly.
