4) Checking power transformer
a. Remove power transformer from control box.
b. Set the range of resistance measurement of
multimeter to "x1Ω"
c. Measure lead line resistance between the yellow
and yellow and between the brown and blue.
d. It is normal that the resistance measured is
accorded with table 1.
5) Checking thermistor
a. Remove thermistor connector from PCB.
b. Check the resistance of thermistor according to
temperature.
