What is the difference between ignition transformer and igniter?

What is the function of ignition transformer?

The ignition transformer takes 120 volts AC and transforms it into 10,000 volts AC to ignite the oil droplets. There are a number of ways to test the output voltage of the transformer.

Can you replace a transformer with a igniter?

It’s not uncommon to realize a component energy savings of 40 percent simply by changing from a transformer to an igniter. My favorite advantage of the igniter is a very consistent and reliable output voltage over varied input voltages.

How do you test an ignition transformer on an oil burner?

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.

What is an ignition transformer?

The ignition transformer is a step-up transformer using copper windings around an iron core. It steps up the incoming voltage of 120 volts to an output voltage of 10,000 volts. This is accomplished by a 90 to 1 primary to secondary winding ratio around the iron core.

How do you test a transformer Ignitor?

Turn on the test power cord switch to power the ignitor. Check for spark across the ignitor clip ends (see Figure 1). If spark occurs, proceed the secondary coil test below. If spark does not jump the gap, or if the spark jumps intermittently, ignitor is defective and should be replaced.

What does an ignition transformer capacitor do?

from what it says the ignition transformer capacitors are there to minimize radio interference caused by ignition coils, they come off from the coils wiring bundle to the capacitors to ground.

How does an ignitor work?

When the button on a Piezo electric ignitor is pressed, a spring loaded hammer strikes quartz in order to start a fire. This is a typical process in lighters. A spark can be created by creating the necessary amount of voltage. The process creates enough energy to produce a spark.

What does an oil burner transformer do?

The transformer converts electric voltage to create the impetus for the igniter to spark. As with igniters, the transformer can be damaged by moisture and leaked oil. It is standard practice for furnace technicians to carry out an output voltage test using a voltmeter.

What is interrupted ignition?

INTERRUPTED DUTY IGNITION is defined by Underwriters Laboratory (UL) as “an ignition system that is energized each time the main burner is to be fired and de-energized at the end of a timed trial for ignition period or after the main flame is proven to be established.” (UL 296, Paragraph 4.21).

Why is my oil burner not firing up?

Oil pump failure of blocked filter, or faulty coil. Incorrectly set electrodes or blockage in the nozzle hosing would prevent your burner from firing. Insufficient air flow to the burner will also prevent your burner from firing. … Oil Line blockage.

Why will my oil furnace not ignite?

Possible causes: The furnace could need resetting. Other possible causes include a faulty connection in the thermostat, a pilot flame in need of cleaning, a switch that’s been turned off or problems with a gas valve.

What is the secondary voltage of an ignition transformer?

The secondary voltage of an ignition transformer in a furnace is 11.1 kV. When the primary operates at an rms voltage of 110 V, the primary impedance is 21.0 O and the transformer is 88.2% efficient.
