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 ame test plug. If the amber LED
remains flashing, the control is defective.
If the amber LED goes 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:
• Attach 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
reinstall and close the burner housing.
• 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:
• Line voltage <90 VAC (amber LED ashes uniquely,
1 second on, 1/2 second off, 1 second on, 3 sec-
onds off, then repeats). Check line voltage.
• Internal fault. CAD cell and line voltage OK. The is-
sue may be an internal fault. Replace the control.
Repeated ame failures ( ashing red LED)
Check for:
• CAD cell is defective. Replace.
• Air leaking into oil line causing ame out. Check oil
line connections and filter gasket.
• Defective nozzle causing ame to be erratic.
Change nozzle.
• Excessive airow or draft causing ame to leave
burner head. Check for proper air band setting and
draft.
• Excessive back pressure causing ame to be er-
ratic. Check appliance and flue for sooting/plugging.
Control locks out at end of TFI ( red LED on)
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.
• Airow 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 ame.
• Check ohms.
• Check CO
2
level.
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.
