How it works
How a gas furnace starts up
Every time your thermostat calls for heat, a gas furnace runs through the same short routine. If one step fails, the furnace stops right there to keep you safe.
Where it stops is the best clue to what broke. Knowing these steps makes gas furnace repair easier to describe on the phone, because you can say exactly where your furnace stopped.
Inducer starts
A small fan pulls exhaust through the vent before any gas flows.
Pressure switch closes
It confirms the vent is clear and drafting.
Ignitor lights
A hot surface ignitor glows, or a spark or pilot lights the gas.
Flame is proven
The flame sensor confirms fire. Otherwise the gas valve shuts.
Blower runs
Once the heat exchanger warms up, the blower motor sends heat to the house.
Match the symptom
Gas furnace troubleshooting: where did it stop?
Furnace won't light? Watch and listen through one start-up.
You don't need to open anything. Just notice what happens, then tell the pro when you call.
A furnace won't light for several reasons, so match what you see to the chart before you call.
| What you notice | Likely spot | Often points to |
|---|---|---|
| Nothing at all. No click, no hum | Power or controls | Thermostat, furnace switch, breaker, door switch or control board |
| Inducer hums, then stops | Venting | Pressure switch, blocked vent or a clogged condensate line |
| Ignitor glows, no flame | Gas supply | Gas valve, closed gas shut-off or low propane |
| Lights for 3 to 4 seconds, then quits | Flame signal | Dirty flame sensor, the most common failure |
| Flame stays on, but the air blows cold | Blower or limit | Blower motor, capacitor or an overheating limit switch |
| Loud boom when it lights | Stop using it | Delayed ignition. Dirty burners or low gas pressure |

Safety check
Furnace flame color: what it is telling you
A healthy gas flame is steady and blue. You can often see it through the small window on the front panel. A yellow, orange or lazy, wavy flame means the gas isn't burning cleanly.
That matters because dirty burning makes carbon monoxide. Dust, rust, a cracked heat exchanger or poor venting can all cause it.
Seeing yellow? Turn the furnace off at the thermostat and call to have it checked.
Steady blue
Gas is burning cleanly. This is what you want to see.
Yellow or orange
Gas isn't burning right. Carbon monoxide risk. Turn it off and call.
Lifting or wavy
The flame is being pushed around. Often a draft or heat exchanger problem.
Soot or scorch marks
Burning has been dirty for a while. Don't run it until it's checked.
Smell gas or hear hissing? Don't troubleshoot. Don't flip switches or light anything.
Get everyone out, then call SoCalGas at 1-800-427-2200 or 911 from a safe place. Never try to repair a gas line, valve or meter.
Propane customers should also call their propane supplier. SoCalGas leak guidance
Standing pilots
Pilot lights on older gas furnaces
Some older homes around downtown Beaumont still have a furnace with a standing pilot light. It's a tiny flame that stays lit all the time.
Next to it sits a thermocouple, a small sensor that tells the gas valve the pilot is lit.
If the pilot keeps going out, the thermocouple is a common culprit. A dirty pilot tube or a drafty closet can cause it too.
Did the pilot go out after the gas was shut off? SoCalGas offers pilot relights at no charge, and the visit can include a basic furnace safety check. If it keeps going out after that, call a heating pro.
Propane homes
Propane furnace repair has its own rules
Homes that aren't on a natural gas line often heat with propane. You'll see it more on rural lots out toward the edges of the Pass and in some manufactured homes.
The furnace works almost the same way. The fuel supply is the difference.
Propane is stored as a liquid in a tank, so propane furnace repair often starts with a quick fuel check.
Propane furnace repair often starts with the fuel supply, not the furnace. The big one is running out.
When a propane tank runs dry, the system must get a leak check before it's turned back on. That's because an open valve or line can leak once the tank is refilled.
Your propane supplier handles this, and the pilot lights get relit after.
- Check the tank gaugeMany tanks show a percentage. Many suppliers suggest ordering before it drops to 20 or 30%.
- Other appliances out too?If the stove won't light either, it's likely the tank, not the furnace.
- Don't relight it yourselfAfter a run-out, wait for the supplier's leak check.
- Converted furnace?Natural gas furnaces need a conversion kit to burn propane. A wrong setup burns dirty.
Propane customers
Before you call about a propane furnace
Propane isn't the same as natural gas. The fuel comes from a tank, so the first question is often simple: is there any left?
| Situation | Who to call first |
|---|---|
| The tank may be empty or the gauge reads low | Your propane supplier |
| You smell gas or hear hissing | 911 and your propane supplier, from outside |
| Furnace won't light, and the tank has fuel | A company that works on propane equipment |
| The regulator, valve or tank looks damaged | Your propane supplier. Don't touch it |
Regulators, valves and tank fittings are for qualified people only. Natural gas and propane equipment use different supply and pressure settings, so ask whether they service propane before they come out.
Is your furnace natural gas or propane? Tell us when you call, so we can prepare for your system.
Side by side
Natural gas vs. propane furnaces at a glance
The furnace inside is almost the same. The fuel, the smell and who you call are not.
Not sure which one you have? Look outside for a tank.
No tank usually means a SoCalGas line. Running on electricity instead?
Our electric furnace repair page covers that, and our gas vs. electric guide compares the two.
| Natural gas | Propane | |
|---|---|---|
| Where the fuel comes from | A SoCalGas line to the meter | A tank on your lot, filled by a supplier |
| Who you call about a leak | SoCalGas or 911, from outside | Your propane supplier and 911, from outside |
| If the fuel runs out | Rare. Usually a shut-off or a meter issue | Common. Needs a leak check before relighting |
| Pilot relights | SoCalGas offers them at no charge | Your supplier relights after the leak check |
| Burner setup | Natural gas orifices and valve setting | Needs a propane conversion kit |
| Typical homes here | Most Beaumont, Banning and Calimesa homes | Some rural lots in Cherry Valley and on the edges of the Pass |
Both fuels make carbon monoxide when they burn dirty. Accidental CO poisoning sends more than 20,000 Americans to the ER each year. A yellow flame on either fuel means turn it off and call.
Older gas furnaces
Gas furnace repair or replacement: fix it or start thinking new
A gas furnace usually lasts 15 to 20 years. So a younger furnace with one worn igniter or a dirty flame sensor is almost always worth fixing.
The math changes when the same furnace keeps breaking down, or the heat exchanger is cracked. Some older homes near downtown Beaumont still have these pilot-style units.
Older units are often 80% AFUE or lower. Newer high-efficiency models reach 90% or more, so they burn less gas for the same heat.
Constant short cycling, cold rooms at the end of long ductwork, or the third repair in one winter are signs to ask the bigger question. Our furnace replacement guide walks through it.
Hands off
Gas furnace parts you should never touch
Some furnace parts are safe to look at, and some are not. These gas parts are for qualified people only.
| Don't touch | Why |
|---|---|
| Gas valve | A wrong move can leak gas or stop the furnace from shutting off safely. |
| Gas meter | It belongs to the gas utility. Call SoCalGas if something looks wrong. |
| Gas piping and fittings | Leaks can start fires. Never test with a flame. |
| Propane regulator and tank valve | Your propane supplier handles these. Don't adjust them. |
| Pilot assembly after a gas smell | Leave it alone until a pro says it's safe. |
For a leak or a low tank, call the gas utility or propane supplier. For a furnace part that isn't working, a heating contractor is the right call.

FAQ
Gas and propane furnace repair FAQs
Why won't my gas furnace light?
Start with the simple things. Check the thermostat, the furnace switch, the gas shut-off valve and, on propane, the tank level.
If those are fine, the ignitor, gas valve, pressure switch or control board is usually to blame. Watch one start-up and note where it stops, then call and tell the pro exactly what you saw.
Why is my furnace flame yellow?
Because the gas isn't burning cleanly. Common causes include dirty burners, a blocked air opening, poor venting or a damaged heat exchanger.
A yellow or orange flame can raise carbon monoxide levels in the home. Turn the furnace off at the thermostat, check that your CO alarms work, and have it checked before using it again.
What should I do if I smell gas?
Leave the house right away. Don't flip switches, use your phone inside or light anything.
From outside, call SoCalGas or 911. If you heat with propane, also call your propane supplier.
Don't go back in until they say it's safe. Gas smells like rotten eggs because a warning odor is added on purpose.
Can I relight my furnace pilot light myself?
Sometimes. Many older furnaces have relight steps printed on a label inside the door.
If you're unsure, or the pilot keeps going out, don't keep trying. SoCalGas customers can schedule a pilot relight at no charge.
A pilot that won't stay lit usually points to a worn thermocouple, which needs a pro.
What happens if my propane tank runs out?
The furnace and other propane appliances stop. Close the tank's service valve and call your supplier.
Safety rules require a leak check before the system goes back into service, because an open line can leak once the tank is refilled.
The supplier refills the tank, tests the lines and relights the pilots for you.
Can a natural gas furnace run on propane?
Only with the right conversion kit. Propane runs at a different pressure, so the burner orifices and the gas valve setup must change.
A furnace set up for the wrong fuel can burn dirty, soot up and make carbon monoxide. This is a job for a licensed pro with the maker's kit, not a weekend fix.
Why does my furnace make a loud boom when it starts?
That's usually delayed ignition. Gas builds up for a moment before it lights, then lights all at once with a bang.
Dirty burners, a weak ignitor or low gas pressure can cause it. Stop using the furnace and call, because repeated booms can crack the heat exchanger and let carbon monoxide into the home.
