What is the purpose of the 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.
What is an ignition transformer oil furnace?
The transformer converts electric voltage to create the impetus for the igniter to spark. It is standard practice for furnace technicians to carry out an output voltage test using a voltmeter.

How do you check a spark on a 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.
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 a spark transformer?
Botanica is a Bellarian. The spark is the core of Transformer life, an electrically charged mass of positrons formed from the supernatural substance known as Rarified Energon. When a Transformer’s body can no longer support its spark, it is “extinguished” and the Transformer is considered dead.

How to Test an Oil Burner Transformer
- Shut off the power to the oil burner.
- Open the inspection panels to the burner, find the transformer and loosen it to where you can move it around.
- Disconnect the power to the motor so no oil will come out while you check the transformer.
Why is my oil burner not firing up?
Common causes for oil boiler lockout include: A leak in the system causing low boiler pressure. A fault in the thermostat, e.g. a problem with the radio frequency (RF) pairing which means that the boiler does not know when to fire up.
Why won’t my oil furnace fire up?
Can a transformer get weak?
Low-voltage transformers do not wear out. A technician should troubleshoot the transformer and find the reason it failed before replacing it. Usually, a transformer fails only after another part in the electrical circuit shorts to ground or draws an unusually high amperage.
What do you need to know about a furnace transformer?
It also helps to know the internal mechanics of a transformer. The furnace transformer is comprised of two systems that make up the furnace transformer wiring. The first system is for the supply voltage and the other is for the secondary voltage.
Where is the low voltage transformer on an oil furnace?
Oil Furnace Ignition Repair and Transformer Replacement Low voltage transformers can be found on the zone valves or on the thermostat of your furnace. When the transformer stops working properly, it can lead to problems with your furnace such as the igniter failing to start and the furnace overheating.
What causes a furnace transformer to stop working?
A: Most of the time, the furnace transformers will stop working because it couldn’t convert the right voltage to start the ignition, controls and timers. This can be caused by a faulty wire in the transformer or just an old furnace. Q: What does a furnace transformer do?
How many volts does an ignition transformer take?
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.
