Code Fault Diagnosis Step
Remedy
None
Open FC3 and/or F1
Fuses
1. Check for faulty Gas Valve
wiring.
Inspect Gas Valve wiring. Ensure insulation on wiring is not worn. If OK, proceed to
step 2.
2. Verify that Gas Valve is not
defective.
Mesure for resistance across Gas Valve terminals and between each terminal and
ground. If short exists, replace Gas Valve. If OK, proceed to step 3.
3. Check for faulty Control Module
wiring.
Inspect Control Module wiring. Ensure insulation on wiring is not worn. If OK
proceed to step 4.
4. Control Module is defective.
Replace Control Module.
None
Open FC4 Fuse. 1. Check for faulty Igniter wiring.
Inspect Igniter wiring. Ensure insulation on wiring is not worn. If OK, proceed to
step 2.
2. Check for faulty Blower wiring.
Inspect Blower wiring. Ensure insulation on wiring is not worn. If OK, proceed to
step 3.
3. Check for defective Igniter.
Disconnect Igniter plug from Control Module. Measure resistance across Igniter.
Resistance should be 10.9-19.7 ohms at at 77°F. If out of this range, replace igniter. If
OK, proceed to step 4
4. Check for defective Blower.
Disconnect Blower plug from Control Module. Measure resistance across Blower
windings. Winding resistance across lead should be in the following range: Red-to-
White: 8 to 9 ohms. If measured values vary substantially from these values, blower
is defective. Replace. Otherwise proceed to step 5.
5. Control Module is defective.
Replace Control Module.
bD
Bad Board or
Secondary Hig
Voltage Fault
1. Verify that FC4 Fuse on Fuse
Board is not open.
Remove FC from fuseholder. Mesure continuity across fuse. If OK, reinstall fuse and
proceed to step 2. If Fuse is open, proceed to section titled ‘‘Open FC4 Fuse’’.
2. Verify high voltage output from
Fuse Board.
Disconnect plug from P6 connector of Fuse Board. Measure for 120VAC across pins
3 and 5 of P6 receptacle on Fuse Board. If OK, reconnect plug and proceed to step 3.
If not OK, go to step 4.
3. Check for defective Harness.
Disconnect plug from E10 connector of Contol Module. Measure for 120VAC across
pins 1 and 3 of Plug on Harness. If OK, replace Control Module. If not OK, replace
Harness.
4. Check for defective Transformer.
Disconnect plug from P4 connector of Fuse Board. Measure for 120VAC between
pins 4 and 6 of plug from Transformer. If OK, proceed to step 5. If not OK, replace
Transformer.
5. Fuse Board is defective
Replace Fuse Board.
EE
Bad Board 1. Defective Control Module
Replace Control Module.
CE
Communication
Error between
Control Module and
Display Interface
Assembly
1. Disconnect and then re-connect
power to heater.
2. Check for faulty wiring or
connection.
Inspect Display Interface Wiring. Ensure Display Interface Plug is securely attached
to Control Module. If OK, proceed to step 2.
3. Control Module and/or Display
Interface Assembly are defective.
Replace Control Module and/or Display Interface Assembly.
IO
Igniter Failure 1. Check for faulty wiring or
connection.
Inspect Igniter wiring. Ensure Igniter Plug is securely attached to Control Module. If
OK, proceed to step 2.
2. Igniter is defective
Replace Ignitier.
Sb
Keypad Failure 1. Keypad is defective
Replace Display Interface Assembly.
SF
Temperature sensor
input failure
1. Check for faulty wiring or
connection.
Inspect sensor wiring. Ensure sensor is pluggd into back of control module. If OK,
proceed to step 2.
2. Sensor is defective
Replace temperature sensor.
