Quick answer
Gas furnace repair usually centers on the startup sequence: the inducer motor and pressure switch prove safe venting, the ignitor lights the burners, and the flame sensor proves flame within a few seconds. Failures at each stage produce distinct symptoms, from no ignition at all to burners that light and drop out immediately. Diagnosis reads control-board fault codes and tests components rather than replacing parts on a hunch.
The startup sequence, step by step
- The thermostat closes a heating call to the control board.
- The inducer motor starts and establishes draft through the vent.
- The pressure switch confirms that draft before ignition is allowed.
- The hot-surface ignitor glows, or a spark ignitor fires.
- The gas valve opens and the burners light.
- The flame sensor proves flame within a few seconds or the valve closes.
- After a short delay the blower starts and warm air reaches the registers.
Where gas furnaces can break
| Stage | Symptom | Common cause |
|---|---|---|
| Draft | Inducer runs, nothing else happens | Pressure switch, blocked vent or drain, condensate backup |
| Ignition | Click or glow, no flame | Failed ignitor, gas supply, gas valve |
| Flame proving | Lights for 3-7 seconds, then quits | Dirty or failed flame sensor, grounding issue |
| Heat rise | Runs briefly, then trips off | Restricted airflow, dirty filter, limit switch |
| Distribution | Burners fire, no air movement | Blower motor, capacitor, control board |
Condensation and high-efficiency furnaces
Many newer Akron-area furnaces are condensing models with PVC intake and exhaust piping. They create acidic condensate that has to drain freely. A plugged drain, a fouled trap or a frozen termination outdoors can shut the furnace down through the pressure switch.
That is one reason a furnace can fail on the coldest morning of the year and appear fine the following afternoon.
Gas safety, without the drama
- A strong gas odor means leave the home and call the gas utility or emergency services from a safe location. Do not troubleshoot the furnace.
- Do not adjust the gas valve, gas piping or burner assembly.
- Do not defeat pressure switches or limit switches to force the furnace to run.
- Follow the alarm manufacturer's guidance if a carbon monoxide alarm activates, leave if directed and contact emergency professionals.

Frequently asked questions
- Why does my gas furnace light then shut off after a few seconds?
- That pattern can point to flame sensing. The furnace lights but does not receive proof of flame, so the control board closes the gas valve as designed.
- Is a flashing light on my furnace useful?
- Yes. Many control boards flash a code that narrows the fault considerably. Note the pattern before power is cycled.
- Do gas furnaces need annual attention?
- Manufacturers generally recommend annual maintenance, which can include combustion, flame-sensing, airflow and safety-control checks.
