How do I test my Beckett electronic igniter?

How do I test my Beckett electronic igniter?

CAUTION Just like an iron core transformer, an electronic ignitor is most simply tested by supplying it with 120 V input and observing whether it produces an arc. This may be done by looking or listening to see if there is an arc across the electrodes while the burner is running and the ignitor is energized.

How do you test an igniter transformer?

There are a number of ways to test the output voltage of the transformer. The most accurate is to use a voltmeter capable of measuring 10,000 volts. With 120 volts input to the transformer, the output should be approximately 10,000 volts. If below 9,000 volts, the transformer is weak and should be replaced.

How do you test a Beckett burner transformer?

How to Test an Oil Burner Transformer

  1. Shut off the power to the oil burner.
  2. Open the inspection panels to the burner, find the transformer and loosen it to where you can move it around.
  3. Disconnect the power to the motor so no oil will come out while you check the transformer.

How do you test a CAD cell?

To check cad cell operation, use the following procedure: ³ Disconnect cad cell leadwires; then start burner. Shortly after burner starts, place a temporary jumper between terminals F-F. Connect an ohmmeter across cad cell leadwires; resistance should be less than 1600 ohms. Stop burner and remove temporary jumper.

How long do boiler electrodes last?

Every 5 years boilers will normally have worn electrodes, and typically issues with automatic air vents or sensor drift may have occurred.

How do you troubleshoot a Beckett oil burner?


  1. Turn the power off to the burner. Loosen control. Verify there are not any exposed wires.
  2. Remove yellow cad cell wires from the back of the GeniSys Primary Control. Turn the power back on. The flame light should go out on the Primary Control.

What should a CAD cell read in the dark?

The cad cell in darkness has a very high resistance to the flow of electrical current. Yet, in the presence of visible light, it has a very low resistance. For a properly adjusted burner, during operation, the cad cell resistance should be approximately 300-1000 ohms, but not more than 1600 ohms.

How do you troubleshoot a CAD cell?

In order to troubleshoot the Cad Cell, disconnect the Cad Cell wires from the oil primary control and connect a multimeter to the two yellow leads from the Cad Cell. One multimeter probe is connected to each wire and the meter is set to resistance to measure ohms. Turn the burner on by connecting the T and T terminals.

How do you clean a spark electrode?

If you have to do a more extensive cleaning job, use a toothbrush and bleach-free cleaner, such as water and baking soda, vinegar or dish soap. After scrubbing off the electrode and the base, dry both with a paper towel and try the burner. You should see a strong bluish spark and the gas should ignite readily.

How to test a hot surface ignitor?

How to test a hot surface ignitor to see if it is bad. If you see that your hot surface ignitor is not turning on, take a resistance reading on the ignitor. First, open up your furnace so you can access the ignitor. The ignitor is located behind the burner assembly. Next, use a multimeter to probe the ignitor connector.

How to bench test an ignition coil?

Prepare the multimeter To check a 12 volt coil,set the multimeter to at least a 200 Ohms setting.

  • Test the resistance The normal,acceptable range for a standard 12-volt car is 1.5 to 1.7 Ohms. See if the reading is within this range.
  • Test the secondary coil resistance
  • How to tell test furnace igniter and circuit board?

    Begin with turning off the furnace at the electrical switch placed on its side. The button looks like a regular light switch.

  • Identify the ignitor; typically is in the upper right. It features a white base with a black part going into the furnace port.
  • Once you’ve spotted the ignitor,you will also have to remove the screw/screws that keep it in place.
