Why is my furnace turning on but not igniting? ›

If your gas furnace initiates the start cycle but does not fire up, it's likely because of a faulty, damaged, or dirty ignitor/sensor. This is a very common furnace problem — you can try to clean the sensor and replace the ignitor.

Why is my heater clicking but not igniting? ›

Defective Igniter or Pilot Light

If it makes a clicking noise but your furnace won't ignite after its combustion cycle, then it's more than likely going to need to replace the electronic ignition systems.

Why is my gas heater flame not igniting? ›

If your furnace won't ignite, the source of the issue may be a broken flame sensor. The sensor is responsible for turning off the gas burners to avoid gas buildup. Once this component starts to malfunction, it may stop the burners from igniting altogether.

How do I reset my furnace ignitor? ›

Reset The Furnace Ignitor

Find the burner door on the furnace and look behind it to find the ignitor. Turn it to “OFF” and wait for five minutes. After you wait, turn it back on and return the door to the burner. It is important to make sure the switch on the door is properly engaged.

How do I force my furnace to start? ›

The system should have a reset switch. Turn it to “OFF,” and wait 5-10 minutes to give the gas time to dissipate. Hold in the reset switch and use either a match or lighter to relight the pilot light. Try to do this step relatively quickly so too much gas doesn't dissipate around the furnace.

How do you know if the igniter is bad? ›

If you have a faulty furnace ignitor, it won't produce that tiny spark to heat the air coming from your Furnace. Your heater blows air at the same temperature as the cold outside air without it. Cold air blowing through your vents is a good sign that you have a heating problem within the Furnace.

Why is my forced air heater not igniting? ›

If your furnace is not turning on you should first check if the filter is clean. Dirty filters cause insufficient airflow and can prevent the furnace from starting. Other reasons it won't start can stem from improper thermostat settings, forgetting to turn on the gas line, or faulty pilot light.

Why does my HVAC unit click but won't start? ›

If the AC unit clicks but doesn't turn on or makes repeated clicking noises during cooling, there may be issues with certain components, such as the compressor, capacitor, fan, thermostat or other mechanical/electrical parts.

Why does my thermostat click but my furnace doesn't start? ›

If the thermostat clicks but the AC or furnace doesn't turn on, most often it's because the filter is clogged. A blocked filter will restrict airflow. The particles it's designed to trap eventually clog the filter media, and the system will be unable to generate heat or cool air.

Why is the flame light not coming on my furnace? ›

The Pilot Light is Out

Check to see if it has gone out. If it has, you will need to relight it. If it keeps going out, there may be an issue with the gas line or the pilot assembly needs cleaning. Call an HVAC professional to check it out.

Why is my pilot light not lighting gas fire? ›

Check the Spark Igniter

If gas is coming out of the pilot but it still won't light, the spark igniter could be the problem. You should clear out any debris between the igniter and thermocouple. Blow compressed air into the pilot area, wait a couple of minutes, and then try again to see if this fixes the problem.

Why is my furnace turning on but not heating my house? ›

The first step in diagnosing the issue is to check your thermostat settings. Ensure that it's set to “Heat” mode and the desired temperature is higher than the current room temperature. Sometimes, the thermostat might be accidentally set to “Cool” or “Fan Only,” causing the furnace to run without heating.

What would cause a furnace not to kick on? ›

If your furnace does not turn on, you may have a dirty flame sensor. The flame sensor is a safety device that confirms whether a flame is present to allow the gas valve to open. Over time, this metal rod - known as the flame sensor - gets coated in carbon deposits, dust, and other contaminating materials.

Why is my furnace humming but not igniting? ›

If the hum occurs when the motor is on but not turning, the capacitor may be damaged and, if so, should be replaced. This could result from a poor quality capacitor or a blocked filter. Humming when the blower is off usually indicates that the pilot light needs to be readjusted to the appropriate level.
