If corrosion is found on the Molex connector replaced the wiring harness. NOTE: In either case above, the source of the moisture needs to be located and corrected. Inspect the condensate trap, burner housing gasket, condensate collector and for any signs of cross contamination, as these can be the source of the moisture. If moisture or corrosion is NOT found and the connections are secure perform the following. Disconnect the Molex connector from the (T1 and/or T2 sensor). Using a digital multimeter
