So if the button won’t reset, or quickly pops up again, it’s time to call a professional repair service.
What causes oil burner lockout?
What Is A Boiler Lockout? A boiler lockout is a shut-down procedure that is initiated when a boiler is not working within certain tolerances. This could be due to low/high water pressure, lack of or no fuel supply (gas, LPG or oil), a blockage in the system or lack of power to electronic components.

How do you fix a short cycle on a furnace?
Dirty Flame Sensor Once the sensor becomes contaminated with dirt, it will be unable to detect the presence of flames and will shut the furnace off. The easiest way to fix a furnace that is short cycling is to remove the flame sensor to clean it. Use a sponge or brush to remove the dirt from the sensor.
Why does my furnace shut off after 15 minutes?
Short-cycling is when a heater doesn’t complete its regular heating cycle and turns off early. A full heating cycle for a furnace or heat pump is usually around 15 minutes or more. If your heater keeps turning off after only five minutes, that’s too short—no matter how low you’ve set the thermostat.
Why does my heater keep running after it has reached the set temperature?
When your furnace keeps running after the temperature has been reached: Check the blower motor – Your forced air heating system uses a blower to push air through ducts and into your living space; sometimes, the blower runs at the same time that your furnace is heating the air, but sometimes it runs on its own.
What is a hard lockout?

What is oil burner lockout?
When a boiler recognises a fault, most commonly through its flame sensor, it has a safety mechanism to automatically lock-down to prevent further damage. This safeguard is referred to as lockout in oil fired boilers. Another cause could be a blockage or restriction in the system that disrupts the oil feed pressure.
How do you reset an oil burner after running out of fuel?
