Upon arrival I found heavy corrosion in heat exchanger and on burners. I found hot spots on heat exchanger. I found water lines from multiple floods in basement up to 5ft. The customer replaced blower motor and control board. The roll out sensor was removed from furnace. The control board does nothing, only runs blower. The Led light doesn't light up. Jumped r to w and board does nothing. I bypassed safeties for testing purposes only. No change. Only blower runs. Due to age, condition, efficiency, and costly repairs recommended replacement. I quoted new system. Carrier
