Service & Troubleshooting

Burner (control) will not come on

No power to control

• Check limit circuit to the control (at least 102 VAC).

• Check all electrical connections.

Control is in lockout

• Red LED will be on. Press the reset button for 2 sec-

onds.

CAD cell seeing light

• Green LED on, and amber LED blinking 1 second

on, 4 seconds off. Remove one yellow lead from FF

terminals, and the flame test plug.

•

If the amber LED remains flashing and green LED

on, the control is defective.

•

If the amber and green LEDs go OFF, the control is

OK, and;

• light is leaking into the burner housing, or

• CAD cell is defective, or

• There is a problem with the CAD cell wiring or

holder.

• If appliance was recently shut down, CAD cell may

see residual hot spots in chamber.

To troubleshoot:

• Check CAD cell by plugging a 3.5mm mono plug

into the CAD jack after entering TFI, or before a call

for heat (for dark chamber checks). Attach the plug

to a multimeter to monitor CAD cell resistance. Dark

resistance should be over 50K OHMS, and room

light resistance (control flipped open) should be at

most 10K OHMS. Replace cell if necessary, or rein-

stall and close the burner housing.

Control will not start if the plug is inserted.

•

Also, if the plug is inserted more than two minutes,

the control goes to Standby.

• Check for stray light by measuring the CAD cell

resistance looking into the inactive combustion

chamber. It should read at least 50 kohms.

Other no-start problems

If the CAD cell is OK, and the amber LED still blinks 1

second on, 4 seconds off, the other possible failures

include:

• Valve lead voltage on too early. Correct bad connec-

tion.

• Line voltage <90 VAC (amber LED flashes uniquely,

1 second on, 1/2 second off, 1 second on, 3 sec-

onds off, then repeats).

• Internal fault. If valve has no voltage, and line volt-

age OK, the issue may be an internal fault. Replace

the control.

FROZEN PIPES/WATER DAMAGE: This is not a freeze protection device. Suitable freeze protection monitoring or

other precautions are recommended to protect against ruptured pipes/water damage caused by fuel outage, safety

related fault conditions, or equipment failures.

Repeated flame failures (

Check for:

• CAD cell is defective. Replace.

• Air leaking into oil line causing flame out.

Check oil line connections and filter gasket.

• Defective nozzle causing flame to be erratic.

Change nozzle.

• Excessive airflow or draft causing flame to leave

burner head.

Check for proper air band setting and draft.

• Excessive back pressure causing flame to be er-

ratic. Check appliance and flue for sooting/plugging.

Control locks out after TFI (

Check for:

• No oil to burner. Check oil supply, filters, lines.

• Shorted electrodes. Inspect for cracked porcelain

and replace as needed.

• Poor spark. Check electrode spacing and condition

per burner manual. Replace or realign if necessary.

• Nozzle clogged. Replace nozzle.

• Airflow too high. Check air band setting.

• Ignitor module defective. Replace if no spark.

• CAD cell defective

• Oil valve (if used) stuck in closed position.

• Check wiring connections.

Blinking Green LED

• Weak or unstable flame.

• Check ohms.

• Check CO

level.
