How do I test my oil boiler photocell?

ANSWER:

  1. To check photocell, remove (disconnect) from control box.
  2. Check resistance of the solenoid coil; blue and brown wires (1.47 kohms) and blue and black wires (1.4 Ohms) readings should be within 10% of these figures.
  3. Check voltage on white wire to terminal 7 of 530 SE control box.

What does the photocell on an oil boiler do?

Photocells detect whether the boiler has lit and are fundamental to safe operation of the unit. A dirty or glazed photocell may not be able to detect the burner flame correctly and may cause the boiler to shut down randomly.

How do you clean a photocell sensor?

Clean the sensor. Use a soft cloth moistened with a cleaning solution such as window cleaner. Remove accumulation of dust and mildew, as well as any insects and spider webs from the fixture and bulb.

How do you test a photocell sensor?

The easiest way to determine how your photocell works is to connect a multimeter in resistance-measurement mode to the two leads and see how the resistance changes when shading the sensor with your hand, turning off lights, etc. Because the resistance changes a lot, an auto-ranging meter works well here.

Why does my oil boiler keep cutting out?

Obstructed airflow: Sometimes the reset button gets tripped because the furnace isn’t receiving enough airflow. Dirty flame sensor rod: Every now and then, the flame sensor rod gets dirty and shuts the furnace off. Make sure you wipe it off regularly. Low fuel: Low fuel is also a common cause of burner failure.

How do you reset a Riello burner?

To reset the burner, press the button light on the burner. Wait for the burner to complete the entire start-up cycle again, up to the ignition of the flame. Before it starts pre-ventilation (pre-purging), the oil burner pre-heats the fuel oil for about 2 and half minutes.

Why do photocells fail?

One common problem that affects photocell functioning is incorrect or loose wiring between the photocell and the main circuitry of the lighting system. The wire that connects the photocell to the lighting circuit needs to have a solid, soldered connection. In addition, the system needs to have proper electrical power.

How can I tell if my photocell is faulty?

If it fires after 12 secs and then locks out after 5 secs, the photocell is faulty. 2. Check resistance of the solenoid coil; blue and brown wires (1.47 kohms) and blue and black wires (1.4 Ohms) readings should be within 10% of these figures. If faulty then replace coil. 3. Check voltage on white wire to terminal 7 of 530 SE control box.

When to replace a Riello gas control box?

As the affected burners are likely to be pre 1996 CE certification (20 or more years old!) Riello would recommend the complete replacement of the burner including the obsolescent control box to bring them in line with current standards. What replaces the 509 SE gas control box?

Can you supply acoustic shrouds for Riello burners?

The 1400, 2000, 3000 and 4500 GI/EMME range and newer ‘electronic cam’ models. Can we supply Acoustic Shrouds for Riello burners? Yes, these are available for most of the larger burners, type and price can be obtained from our Sales Department. I have 230volt coming into the burner plug but nothing else is happening?
