What Causes a Pilot Light on a Furnace to Go Out in Manvel, TX? Failing Thermocouple & More

When the furnace’s pilot light goes outs, the home can be left with no heat. The pilot light going out does occur common enough to touch on it though this isn’t a frequent problem. Reasons why the pilot light may go out is what we at Absolute P&M Services would like to share today.

Dirty Pilot Cavity

If you can manage to get the pilot light lit for just a moment, inspect the flame. As opposed to a weak yellow flame, the pilot light should be strong blue cone. A weaker flame won’t envelop the thermocouple efficiently. In the pilot orifice, the dirt can easily collect there. A needle or compressed air is involved in cleaning out the pilot orifice, you need to disassemble the pilot and clearing out the debris. To help you out if you’re not eager to start tampering with crucial parts of your furnace system, furnace repair experts at Absolute A/C & Plumbing are just one phone call away.

Faulty Gas Regulator

A bad regulator in your natural gas meter outside your home is affected by all of the gas appliances in your home, including your furnace, dryer, stove, and so forth. Your furnace may not be getting enough gas to keep the pilot lit. If you notice pilot problems in several of your household appliances, this may be the culprit. Immediately, contact your utility company.

Strong Draft & Irregular Air Flow Blows Pilot Light Out

If your pilot light re-lights easily after going out overnight, it possible it was blown out by a draft. On excessively windy days or nights can make this happen. Air can blow into the area from a leak in the output duct of the furnace. Keep every intake air register in your home open and clear to avoid a vacuum effect in the inlet.

Thermocouple is Malfunctioning

If your pilot light won’t stay lit, the thermocouple is very likely the culprit. Being sometimes known as flame sensor, the copper rod the pilot flame directly hits is the thermocouple. A safety mechanism that shuts the gas off should the pilot go out is the thermocouple. If the thermocouple fails to shut off the gas, all the gas flowing through the furnace could get into your home. Against a catastrophic buildup of gas is safeguarded from the thermocouple.

Based on Demand by Fluctuating Natural Gas Availability

There should be no problems on your end. When natural gas consumption peaks, the gas grid in your area may be nearing its capacity and lower the gas pressure intermittently. For the pilot to go out even the slightest hiccup in gas supply, your furnace could be enough. Ask around your neighborhood and find out if anyone else has had issues with their natural gas. Get in touch with your utility company, should the problems persist.
