No Pilot Light On Oil Furnace

A modern gas furnace usually has an electronic spark generator to ignite the gas when the thermostat calls for heat.

No pilot light on oil furnace. And require no pilot light at all. There s no sticking a match into the machine to light the oil or a pilot light but if it is not igniting you can check a few things to make sure. Tape down the safety switch temporarily if you need to keep the panel open to prime the furnace. Furnace sensor rod fix no heat pilot light on.

An older gas furnace has a standing pilot that stays on all the time or at least it s supposed to. This is typically the problem if you can hear your furnace click on but it does not fire up. Oil furnaces will heat automatically. So if you re looking for a pilot light on your newer furnace and can t find one it might be because you don t have one.

Furnace with a pilot light. Because a conventional pilot light burns all times they use and waste more gas. The pilot light in a furnace that ignites the burners is so much a part of our collective understanding of how gas furnaces work that some homeowners find themselves surprised when they discover their new furnace doesn t need a pilot light. A hot surface igniter works similar to a light bulb.

A faulty or dirty ignition or sensor is a relatively easy fix so follow these steps and you may be able to solve the problem yourself. Newer furnaces don t have pilot lights. If your older furnace utilizes a pilot light that won t stay lit the thermocouple may be loose or faulty the pilot orifice may be clogged the pilot s flame may be set too low or the safety cutoff valve may be defective. A true oil furnace or boiler does not not normally have a pilot light.

In the past this was. The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite. A number of things can make an old furnace pilot light go out including a strong draft a faulty thermocouple or a loss of gas. The furnace s electronic control board activates an electric igniter that uses a high voltage spark to light the pilot.

Instead they have some type of electrical ignition system. Once the oil is hot the heat is propelled through the house by way of a furnace fan. The thermocouple is a copper rod that the pilot flame heats up. The small button or dial next to the pilot light opens the valve to release a little gas.

In addition to being less efficient they also aren t as safe and reliable as heating systems with an electronic ignition. In turn the pilot lights the gas for the burners.
