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. 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

Open FC4 Fuse.
1. Check for faulty Igniter
wiring.
Inspect Iginter wiring. Ensure insulation on wiring is not worn. If OK,
proceed to step .
2. Check for faulty Blower
wiring.
Inspect Blower wiring. Ensure insulation on wiring is not worn. If OK,
proceed to step .
3. Check for defective
Igniter.
Disconnect Igniter plug from Control Module. Measure resistance across
Igniter. If shorted, replace Igniter. If OK, proceed to step 4
4. Check for defectiver
Blower.
Disconnect Blower plug from Control Module. Measure resistance
across Blower windings. Winding resistance across lead should be in the
following range: Black-to-White: 10 to 1 ohms, Red-to-White: 18 to
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.

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 . If Fuse is open, proceed to section
titled ‘‘Open FC4 Fuse’’.
. Verify high voltage
output from Fuse Board.
Disconnect plug from P 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 P 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.
