How do you test a boiler ignition 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.
- Return the power to the oil burner and turn it on.
Similarly one may ask, how do you test an 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. The most accurate is to use a voltmeter capable of measuring 10,000 volts.
Hereof, what does a boiler transformer do?
The basic function of the furnace transformer is to supply power to the furnace itself. This can lower the high voltage capacity to a lower voltage output. This is required for Arc furnace operations. You will find that some furnaces need 24 volts to operate.
A bad transformer will have weak power or none at all. If there is power to the unit, it may not be faulty. However, if there is little or no power going to the unit, it may need replacement or repairs.
