Pilot light won't stay on? Read on for reasons why, and what y'all tin do to ready it.
The thermocouple is the copper rod the pilot flame straight hits. Sometimes information technology'due south referred to every bit the "flame sensor." It'due south a safety mechanism that shuts the gas off should the pilot go out. If the thermocouple fails to shut off the gas, all the gas flowing through the furnace could become into your home. The thermocouple safeguards confronting a catastrophic buildup of gas.
DIY Prepare - How to Locate the Thermocouple
Starting time off, take hold of a flashlight and a screwdriver earlier inspecting your furnace. You lot'll have to remove the encompass, and chances are the lighting won't be working in your favor. The but thing more frustrating than a busted furnace is the hundred trips to the garage for tools when you lot're trying to fix it.
For safety's sake, shut off power to the furnace past switching the breaker to the off position, and close the gas valve.
The thermocouple isn't too difficult to find. Locate the pilot light and look for the tip of a copper rod very nearby. That's the thermocouple.
Tin can't Find the Airplane pilot Lite?
If you're having trouble locating the airplane pilot or thermocouple, double-bank check to make sure your unit really has a continuing pilot light. Standing pilot lights are common in older furnaces, but many newer furnaces take intermittent pilot lights or hot surface igniters. In these systems, the pilot will only light (in the case of hot surface igniters, the igniter surface heats) when the thermostat makes a control for estrus.
No matter the pilot configuration, the thermocouple volition be virtually the burners—look for a removable metal rod nearby.
Locate the copper rod near the burners. This is the thermocouple.
If y'all look very closely, you lot'll find the thermocouple tucked in behind the burners.
Why the Thermocouple Fails
The thermocouple needs to find the flame, otherwise it will close the gas valve, and your furnace volition not office correctly. There are three reasons why your thermocouple might be malfunctioning:
It's Broken
A broken or burned out thermocouple won't notice the flame properly, effectively closing the gas valve until you supplant it. Replacing a broken thermocouple is cheap and relatively easy if you're mechanically inclined. Contact professional furnace repair technicians at Hot Point for thermocouple repairs if you aren't so confident. It won't toll you lot much.
It'due south Dirty
Soot buildup on the thermocouple may cake the flame. Under constant exposure to a hot flame, a thermocouple wears down over time. Even a slight residue can make the thermocouple malfunction. The fix here is as easy as removing the thermocouple, cleaning information technology with a wire brush or something coarse (even an ordinary dollar beak works), and replacing.
If removing and cleaning the thermocouple is something yous're comfortable doing, perform this routine maintenance annually. This is DIY furnace maintenance you can perform on your ain to extend the life of your furnace and avert emergency repairs.
It's Not Lined Up
The airplane pilot light flame needs to completely envelop the top of the thermocouple rod so information technology knows the flame is on. If the thermocouple isn't lined upward correctly, it won't read the flame, and volition close the valve for the gas.
If y'all attempt to repair or replace the thermocouple on your own, remember to close the gas valve and shut off power to the furnace by flipping the breaker first to avoid an accident.
ii) Pilot Orifice is Dirty
If you can manage to get the pilot light lit for just a moment, audit the flame. The airplane pilot light is supposed to be a strong blue cone, not a weak yellowish flame. A weaker flame won't envelop the thermocouple properly. The pilot orifice may be full of dirt. Cleaning out the pilot orifice ways disassembling the pilot and clearing out the debris using a needle or compressed air.

3) Bad Gas Regulator
A bad regulator in your natural gas meter outside your home will bear upon all of the gas appliances in your home, including your furnace, dryer, stove, etc. Your furnace may not be getting enough gas to proceed the pilot lit. If yous notice airplane pilot issues in several of your household appliances, this may be the culprit. Contact your utility visitor immediately.
4) Fluctuating Natural Gas Availability Based on Demand
There could exist nothing incorrect on your end. When natural gas consumption peaks, the "gas grid" in your area may be nearing its chapters and lower the gas pressure intermittently. Fifty-fifty the slightest hiccup in gas supply to your furnace could be enough for the pilot to get out. Ask around your neighborhood and find out if anyone else has had issues with their natural gas. Get in impact with your utility company if the problems persist.
5) Improper Air Menstruation, or a Strong Draft, Blows the Pilot Out
If your pilot light re-lights easily after going out overnight, it's possible it was diddled out by a typhoon. This tin happen on excessively windy days or nights. A leak in the output duct of the furnace could cause air to blow into the area. Keep every intake air annals in your home open and articulate to avoid a "vacuum" outcome in the inlet.
