It is very likely that your exhaust Fuselink is faulty. There are two types of fuselink used on the LXI, commonly called the upper (exhaust) high temp and the lower (combustion intake) low temp. Make sure you purchase the correct part for the right location and ALWAYS turn off the power to the heater when changing the sensor.
