- 1. Inspect feed forward (BTU transmitter) sensor for loose or broken wiring.
- 2. Check resistance of sensor to determine if it is within specification.
- 1. Measure the actual exhaust temperature and continuity of the exhaust sensor. If the exhaust temperature is less than 500 o F and the exhaust sensor shows continuity replace the sensor.
- 2. If exhaust temperature is greater than 500 o F, check combustion calibration. Calibrate or repair as necessary.
