14. Component and Circuit Checks
1. Combustion Fan Circuit
a) Check the Motor
b) Check the combustion fan if the error indicator displays “61”.
c) Measure resistance between Black-Red of the PCB connector (
B
1
).
Normal: DC15~46V (when fan ON)
DC0V (when fan OFF)
If normal proceed to check the rotation sensor
Faulty: Replace PCB
Check for the Fan Rotation Sensor
a) Measure resistance between Black-Yellow of connector (
B
1
).
Normal: DC11~13V
If normal proceed to b.).
Faulty: Replace PCB.
b) Measure resistance between Black-White of connector ( B
1
).
Normal: DC5~10V (20~400Hz)
If normal proceed to Sparker Circuit 2.
Faulty: Replace Combustion Fan.
2. Igniter Circuit
a) Measure resistance between Grey-Grey of connector ( C
1
).
Normal: AC207~264V
If Normal proceed to b.).
Faulty: Replace PCB.
b) Disconnect connector ( C
1
) and measure resistance between both terminals of the sparker.
Normal: 1M

If not sparking, adjust or replace ignition plug.
Faulty: Replace Sparker.
3. Main Solenoid Valve (SV
0
)
Check the main solenoid if error indicator “11” is displayed.
a) Measure resistance between pink-black wires of main solenoid connector ( I
4
)
Normal: DC11~13V
If normal, proceed to b.).
Faulty: Replace PCB
b) Measure resistance between Main Solenoid connectors.
Normal: 37~43

If normal, proceed to Solenoid Valve SV
1
Faulty: Replace Main Solenoid.
