Chapter 6 - Troubleshooting
Ventilating fan does not work.
First: Make sure that electrical power to the unit is OK and that
the main on/off switch is On.
Second: Check the circuit breakers to be sure they haven’t
tripped. Reset them if necessary. Refer to Re-setting the Circuit
Breakers on Page 60.
CAUTION: Before working on the electrical system,
make sure the unit is Off and the electric power cord
un-plugged.
Third: Remove the rear utility panel (Figure 139 on Page 123)
and check the wire connections to the fans in the rear of the
electronics compartment (Figures 158 and 159 on Page 131).
Make sure the connections are tight. If the ICU fan wiring has been
serviced lately, make sure that the wires have been re-connected
correctly.
Fourth: Are the three circulating fans in the filter/fans
compartment operating as they should? If they are, check to see if
the power cord is securely plugged into the ventilating fan
(Figure 141 on Page 123). If the power cord is secure, you
probably have a bad ventilating fan. Replace the fan. Order P/N
853414 and refer to Page 123 for replacement instructions.
Fifth: If the circulating fans are not working either, check the other
electrical functions in the ICU. If none of the electrical functions are
working, refer to The ICU will not turn on on Page 139.
