Description: | The heater/blower did not completely remove ice and frost formed on the
teflon window under severe winter weather conditions. Also, the sensitivity
of the moisture sensor was temperature dependent and, if the temperature
changd significantly after the sensor had been tuned, the heater failed to
turn on when the window became wet or frosted. This resulted in unflagged
periods of elevated and unrealistic values of liquid water path.
The heater/blower assembly was replaced with an improved version that
incorporates better circuitry, a larger capacity fan, and better airflow
distribution. |
