- chapter 7
Cause
If the problem recurs when the unit is put into operation, replace the INV board.
Check method and remedy
Check thermistor resistance.
Check for pinched lead wire.
Check for wire coating.
Check connector.
Check for wire.
Check the intake temperature of the sensor with the LED
monitor.
When the temperature is far different from the actual temper-
ature, replace the control board.
