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. A furnace should never be allowed to overheat as it will catch fire and could cause severe damage to your property while putting your lives at risk.
Diagnosing Furnace Ignition Problems
Modern furnaces have a warning system built in, a flashing light will tell you the furnace is ‘locked out.’ You will need to shut the power down before removing the front of the furnace. Next is to locate the igniter itself. If the igniter clicks, it is a ‘spark igniter’ and will usually be located within a gas pilot tube next to the gas control valve. If it looks similar to a light bulb and glows, it is a hot surface igniter If you notice cracks in the hot surface igniter, it needs to be replaced without delay.
What Causes The Spark Igniter To Stop Working?
Cracks in the ceramic base and build up of dirt, dust, and oil are the common factors for spark igniter failure. While the latter is not so serious and can be rectified through cleaning, a cracked spark igniter requires replacement.
What Causes The Hot Surface Igniter To Stop Working?
The hot surface igniter or ‘HSI’ can fail due to contact with oil, the electric current in your property being too high or simply because it has reached its usage cycle. The scenario is pretty much the same as before. A clean up should do the trick but cracks mean it’s time to replace the igniter
What Is An Ignition Transformer And What Does It Do?
A perhaps less common problem is ignition transformer failure. 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. We strongly advise against untrained attempts at diagnosing and replacing the transformer. Without the proper knowledge and experience of performing such tasks, you run the risk of electrocution. There may be issues with the wiring connected to the transformer and the burner which are undetectable to unqualified non-professional and should not be tampered with for the same reasons previously stated.
You will be protecting your heater/boiler and safeguarding your property from catastrophic and devastating consequences to your property. If your igniter won’t work after repeated tries, give us a call and leave this complicated and hazardous work to a licensed and fully trained professional furnace technician.

Oil Furnace Ignition Repair: Quick Troubleshooting Tips
Oil Furnace Maintenance and Cleaning
Proper maintenance and cleaning of your oil furnace are crucial for ensuring that it operates efficiently and safely. By adhering to a scheduled routine maintenance, we can prevent common issues such as furnace ignition failure.
Conducting Regular Check-ups
It’s important for us to perform check-ups on the oil furnace regularly. This helps us catch potential problems early on. During these check-ups, we should inspect the burner and ignition transformer for signs of wear or damage. We need to look out for any dirt, soot, or dust accumulation that could hinder the performance of the furnace. Let’s make sure the limit switch and oil line are functioning correctly as well.
Cleaning and Replacing Filters
Air filters play a key role in maintaining the air quality and efficiency of the heating system. We must clean or replace them according to the manufacturer’s recommendations. Typically, this involves turning off the furnace, removing the filter, and using compressed air to clear away any accumulated dust. If the filters are too dirty or damaged, we’ll need to replace them with new ones to ensure adequate airflow.
Inspecting and Lubricating Motors and Bearings
Lastly, the blower motor and bearings call for our attention; they require regular lubrication to operate smoothly. Over time, they can become dry, which potentially leads to overheating or inefficiency. We should carefully inspect these components and apply the appropriate oil to any lubrication ports. Doing so extends the lifespan of the motor and bearings and upholds the furnace’s operation.
Troubleshooting Oil Furnace Ignition Issues
When we approach the task of troubleshooting oil furnace ignition issues, it’s crucial to carry it out in a systematic way. Let’s focus on identifying essential components, diagnosing common faults, and undertaking the reset or replacement of faulty parts.
Identifying Ignition Components
First, we locate and understand the key ignition components of our oil furnace. The igniter, which may be a high-voltage spark or hot surface element, is crucial for initiating combustion. Alongside the igniter, the transformer provides the necessary voltage. The electrodes generate the spark, while the blast cone focuses the flame into the combustion chamber. It’s important to examine these components within the access panel.
Diagnosing Common Ignition Faults
To diagnose ignition problems, we check for a range of faults:
- Igniter: Ensure the igniter produces a spark. A malfunctioning igniter or transformer can prevent spark generation.
- Fuel Nozzle: Look for clogging that can inhibit fuel delivery to the combustion chamber.
- Electrodes: These should be properly aligned and clean to allow for proper sparking.
- Thermostat: Test for malfunctions that may prevent signaling for ignition.
- Pressure Switch/Gas Valve: Confirm they are operational, as they play a role in ensuring the furnace can ignite.
- Circuit Breaker: Check for tripped breakers or blown fuses, which can be a simple fix to restoring function.
Following a sequence helps us accurately pinpoint the issue. If the furnace shows signs of overheating or the reset button has tripped, it signals that the system needs a closer look.
Resetting or Replacing Faulty Parts
After identifying the problem:
- Reset Button: If the furnace has simply tripped, pressing the reset button once can resolve the issue.
- Components Replacement: For faulty thermostats, igniters, or fuel nozzles, replacing these parts is often necessary. We recommend consulting the manufacturer’s guidelines or seeking professional assistance for detailed procedures.
Safety is paramount; ensure the power is off before attempting any replacements or repairs. Large-scale issues or complex problems should be addressed by qualified technicians.
