PRELIMINARY CHECKS
1. Make sure limit switch is closed and that contacts are
clean.
2. Check for line voltage power at the oil primary. With
thermostat calling for heat, voltage between black and
white leadwires on oil primary should be 120 Vat.

Trouble is in cad cell or oil

Cad cell is seeing external
light, is defective, or cad cell

Go to step 3.
Disconnect power; check all wiring
connections. Tighten any loose
connections, if necessary, and retest.
If burner motor and ignition still don’t
start, replace oil primary. lf ignition is
on and burner motor is off, check
burner motor and wiring connections
to motor. Replace burner motor, if
necessary.

Burner Starts, Flame Is Established; Then Burner Locks Out On Safety
T
CORRECTIVE ACTION
PROCEDURE
BURNER LOCKS OUT
BURNER KEEPS RUNNING
1. a. Reset safety switch by
pushing red reset button.
b. Disconnect cad cell
leadwires at oil primary.
c. Jumper thermostat
terminals to start burner:
l
Jumper low volt
thermostats at oil
primary.
l
Jumper line volt
thermostats at
thermostat.
d. After flame is established,
but before safety switch
locks out, short cad cell
by jumpering F-F
terminals.
Oil primary control is
defective-replace.
If there
is any doubt that F-F terminals
were jumpered within safety
switch timing, wait 5 minutes,
then repeat procedure
(steps 1a-l d).
Check cad cell with ohmmeter,
see Cad Cell Troubleshooting
table on page 9. If ohmmeter is
not available, go to step 2.
2. a. Disconnect line voltage
power and reconnect cad
cell F-F terminals.
b. Unplug cad cell and clean
face with soft cloth. Check
sighting for clear view of
flame. Replace cell in
socket.
C. Reconnect line voltage
power. Reset safety switch
by pushing red reset
button, and jumper
thermostat terminals
to start burner:
l
Jumper low volt
thermostats at
oil primary.
l
Jumper line volt
thermostats at
thermostat.
3. Reset safety switch and
restart burner.
Replace cad cell with Part No.
130367, go to step 3.
Cad cell is okay.
Check cad cell view of flame,
flame shape, and oil nozzle.
If flame is normal and cad cell
has good view of flame, check
for open circuits in socket
assembly wiring. Replace
assembly, if necessary.a
Cad cell and socket assembly
are okay.
“If cad cell is okay and oil primary appears okay but system continues to lockout on safety, repeat steps 1a-l d using a2700
ohm resistor to jumper F-F terminals. Burner will lock out if oil primary is defective; replace oil primary, if necessary.

(Tradeline model only)
PUSH LEVER
TRIP SAFElY
DOWN TO
SWITCH
TrIppIng the safety switch shutsdown the burner but
does not disconnect the power supply. Turn off
power at system switch or circuit breaker before
servicing the control system, burner motor, oil valve
or ignition to avoid electrical shock.
To trip the safety switch, move the safety switch lever
down until the red reset button pops out and the indicator
light comes on. See Fig. 5. Burner will not operate until
safety switch is reset by pushing in the red reset button.
