Arrived on late for no heat call on basement furnace. Found a fault in the exhaust system; and a fault in the combustion drainage system; and a fault in the electronic control system. The flue pipe was not properly connected. This lead to combustion condensation from dripping into the furnace and ruining parts, rusting out the system. Also believe there is a combustion leak in the flue collection box. Also, observed clog in the combustion drainage system which led to more leaks. There is rust on the high efficiency blower motor. This component is due to fail at any moment. There is water spots on the control board. Received error code for water sensor. Cleaned that system. Checked the sensors. Checked the wiring. They aren’t in great shape but the are passing a signal. The control module is not properly processing the water sensor signal and kicking out an error code. This is appears to have been from the water leaking on the electronics. Will obtain a quote for replacing the part.
