1. Check the Thermostat

First, ensure your thermostat is telling your heater to turn on.

Digital Thermostat

  • Change the batteries if the screen is blank. If the digital display is mixed up, the thermostat could need to be replaced.
  • Make sure the switch is on “heat” as opposed to “off” or “cool.”
  • Make sure the program is displaying the right day and time and is scheduled to “run.” If you’re having a hard time overriding the schedule, set the temperature by using the up/down arrows and pressing the “hold” button. This will cause the furnace to turn on if thermostat settings are an issue.
  • Increase the temperature setting to 5 degrees warmer than the temperature of the room.

If your heater hasn’t started within several minutes, ensure it has power by switching the fan switch from “auto” to “on.” If the fan doesn’t operate, your heater may not have power.

Smart Thermostat

If you use a smart thermostat—like one designed by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting will be determined by the model you have. Take a look at the manufacturer’s website for help. If you’re still unable to get your Wi-Fi thermostat to work, reachl us at 256-270-1196 for heating and cooling service.

2. Check Breakers and Switches

Next, you will need to confirm your breaker and furnace switch are on.

  • Find your home’s main electrical panel. If you have no idea where it is, search for a silver metal box in your basement, garage or closet.
  • Make sure your hands and feet aren’t moist before using the panel or breakers.
  • Look for the breaker titled “furnace” or “heat,” and ensure it’s turned “on.” If you find that the breaker tripped, it will be in the middle or “off” area.
  • Moving one hand, steadily turn the breaker to the “on” location. If the breaker trips right away and pops back to “off,” don’t touch it and call a team member from Bain Heating & Air Conditioning, Inc at 256-270-1196 immediately.

No matter your furnace’s age or brand, it has at least one ordinary wall switch installed on or close to it.

  • Make sure the control is facing up in the “on” placement. If it was turned off, expect your furnace to take up to five minutes to turn on. (If you’re unaware of where your furnace is located, look in your basement, garage or utility closet. It might also be in a crawl space or attic.)

3. Put in a New Air Filter

When we think about heating breakdowns, a filthy, blocked air filter is frequently the top offender.

If your filter is too dirty:

  • Your heating system won’t stay on, or it may get too hot from limited airflow.
  • Your gas costs could go up because your heat is switching on more than it should.
  • Your heating system may break down too soon because a filthy filter causes it to work harder.
  • Your heating may lose power if an excessively clogged filter results in a tripped breaker.

While it depends on what model of furnace you use, your air filter is located in the interior of the blower compartment of your heater, an attached filter case or wall-mounted return air grille.

To replace your filter:

  • Switch off your furnace.
  • Take out the filter and tilt it toward the light. If you can’t view light through it, use a new one.
  • Install the new filter with the arrow motioning toward the furnace to prevent damage.

Flat filters should be replaced every month, while pleated filters should be used for about three months. You may also get a washable filter that will work for about 10 years. If you have children or pets, you might have to replace your filter more often.

To make the process go more quickly down the line, draw with a permanent writing tool on your furnace housing or ductwork to list the airflow direction and filter size.

4. Look at the Condensate Pan

Otherwise known as drain pans, condensate pans capture moisture your heating system draws from the air.

If liquid is dripping out of your heater or its pan has too much water in it, try these steps.

  • If your pan includes a drain (look for a PVC pipe), double-check that it isn’t clogged. If it requires draining, use a special pan-cleaning tablet you can get at home improvement or hardware retailers.
  • If your pan has a pump, take a look at the float switch. If the lever can’t be moved from the “up” position with liquid in the pan, call us at 256-270-1196, because you will possibly have to buy a new pump.
error codes icon

5. Look for Furnace Error Codes

If faults persist, look inside your heating system’s plastic window to check the blower motor’s status. Dependent on the model, the light might also be fixed on the exterior of your heater.

If you notice anything other than a steady, colored light or twinkling green light, contact us at 256-270-1196 for HVAC service. Your heater could be emitting an error code that requires professional help.

6. Brush off the Flame Sensor

If your heater tries to work but switches off without putting out heat, a dirty flame sensor could be at fault. When this takes place, your heating system will attempt to turn on three times before a safety feature powers it down for around an hour.

If you feel comfortable with removing the panels from your heating system, cleaning your flame sensor is a job you have the ability to do personally. Or, one of our heating service specialists has the ability to complete it for you.

If you are confident cleaning the sensor on your own, you need:

  • A 1/4” hex screwdriver or wrench
  • Portion of light grit sandpaper, steel wool or emery cloth
  • A fresh paper towel

As the next step:

  • Shut off the furnace’s power through its wall switch or breaker. If your gas valve isn’t electric, you must shut off the gas along with it.
  • Take off the furnace’s front panel and track the wire to the flame sensor.
  • Unscrew the rod and use your sandpaper, steel wool or emery cloth to carefully scrub the metal rod.
  • Clear the rod with a paper towel.
  • Remount the sensor.
  • Replace the furnace doors.
  • Switch the furnace’s power back on. It may go through a series of examinations before continuing regular heating. If your heating system doesn’t turn on, the sensor might need to be replaced or something else might be wrong. If this takes place, get in touch with us at 256-270-1196 for heating and cooling repair support.

7. Light the Pilot Light

If you have an aging heating system, the pilot light could be turned off. To relight it, look for the guide on a sheet on your furnace, or use these recommendations.

  • Locate the switch below your heater labeled “pilot,” “on” and “off.”
  • Turn the switch to the “off” position.
  • Take a break for at least five minutes to limit the possibility for creating a fire.
  • Turn the dial to “pilot.”
  • Press the “reset” lever as you bring the flame of a long lighter to the pilot light opening.
  • Release the “reset” button once the pilot light is burning.
  • If you have tried the guide twice and the pilot light still won’t light or stay burning, get in touch with us at 256-270-1196 for furnace service.

Check Your Fuel Source

Try using another gas appliance. If it doesn’t work, your natural gas delivery might be turned off, or you might have run out of propane.
