9) Is the change over solenoid (SV3) operating normally?
If error “11” or “71” is displayed, check the change over
solenoid (SV3).
a.
# Disconnect the changeover solenoid (SV3)
connector, and measure the resistance at the
solenoid terminals.
Normal:
1.7 – 2.1 K Ω
If normal, check b below.
Faulty:
Replace the manifold assembly.
(Service Procedure IGE-8, page 49)
b.
Measure the voltage at the changeover solenoid
(SV3), brown – black wires.
Normal:
80 – 100 VDC
If normal, reconfirm gas pressures are correct.
Faulty:
Replace the PCB unit.
(Service Procedure IGE-2, page 47)
