15. Component and Circuit Checks
REU-V2632FFUG / REU-VM2632FFUC
1. Combustion Fan Circuit
Check the Motor
Check the combustion fan if the error indicator displays “61”.
Measure voltages between Black-Red of the PCB connector (
B
1
).
Normal:
DC6~45V (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 voltages between Red-Black of connector (
B
1
)
Normal:
DC11~13V
If normal proceed to b.).
Faulty:
Replace PCB.
b.)
Measure voltages between Black-White of connector (
B
1
)
Normal:
DC6~45V (33~400Hz)
If normal proceed to Sparker Circuit 2.
Faulty:
Replace Combustion Fan.
2. Sparker Circuit
a.)
Measure voltages 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 voltage between both terminals of the sparker.
Normal:
1M
If not sparking, adjust or replace ignition plug.
Faulty:
Replace Sparker.
3a). Main Solenoid Valve (SV
0
) Circuit
(
F
1
)
Check the main solenoid if error indicator “11” is displayed.
a.)
Disconnect Main Solenoid connector (
F
1
) and measure voltage between Pink-Black
Normal:
DC11~13V
If normal, proceed to
b
.).
Faulty:
Replace PCB.
b.)
Measure resistant between Pink-Black of Main Solenoid connectors.
Normal:
37~43
If normal, proceed to Solenoid Valve SV
1
Faulty:
Replace Main Solenoid.
