Common Causes of Oil Boiler Shutdowns

• Dirty Burner: A dirty burner can cause irregular combustion, leading to shutdowns. Regular cleaning and maintenance of the burner can help prevent this issue.
• Faulty Thermostat: A malfunctioning thermostat may incorrectly sense the temperature, causing the boiler to shut off prematurely. Check the thermostat settings and replace it if necessary.
• Fuel Supply Issues: Low oil levels or a clogged fuel line can interrupt the fuel supply to the boiler, causing it to shut down. Ensure the oil tank is adequately filled and inspect the fuel line for any obstructions.
• Air Locks: Air bubbles trapped in the fuel line can prevent the oil from reaching the burner, resulting in shutdowns. Bleeding the fuel line can help remove air locks and restore proper fuel flow.

Troubleshooting Tips

• Check Oil Levels: Ensure the oil tank is adequately filled, as low oil levels can cause the boiler to shut down.
• Inspect Fuel Line: Check the fuel line for any leaks, blockages, or air locks that may be affecting the fuel supply.
• Clean the Burner: Regularly clean the burner and heat exchanger to remove any dirt or debris that may be interfering with combustion.
• Reset the Boiler: If the boiler has a reset button, try resetting it to see if that resolves the issue.
