7.2 Burner Internal Faults

Diesel/Light Oil Burner

Below is a list of scenarios and possible causes for burner failure.

A.  The burner goes through the prepurge period normally. The flame ignites, but the burner goes to lockout 
within five seconds.

a.  The phase/neutral lines are reversed. Correct polarity is critical.

b.  The wiring to ground is absent or ineffective.

c.  The electric eye, light-sensing switch is dirty or defective. Try cleaning they eye. If it still fails, 
replace it.

B.  The burner goes to lockout after the prepurge period because the flame does not ignite.

a.  No fuel in tank or lines.

b.  Air has not been fully bled from the fuel lines.

c.  Check fuel lines. The smallest leak will allow air to enter and prevent ignition.

d.  The fuel filter is dirty. Replace filter.

e.  Nozzle is plugged. Replace nozzle.

f.  The spark is irregular or not present. Re-align electrodes. Check ignition transformer (replace if 
defective).

C.  The burner does not start when the thermostat calls for heat.

a.  Loose wire connection at terminals L or N.

b.  Terminals on the control module are bent or loose

c.  The motor is defective.

d.  The capacitor is defective.

e.  The control box is defective.

D.  For additional information refer to the Wayne model FH manual, included in your data package.
