Furnace Repair Checklist

1. Examine the Thermostat

First, make sure your thermostat is telling your heat to start.

Digital Thermostat

  • Replace the batteries if the display is blank. If the digital screen is mixed up, the thermostat may need to be swapped out.
  • Ensure the switch is switched to “heat” rather than “off” or “cool.”
  • Ensure the program is showing the right day and time and is programmed to “run.” If you’re having problems overriding the program, set the temperature by utilizing the up/down arrows and using the “hold” button. This will cause the furnace to ignite if thermostat is causing a problem.
  • Increase the temperature setting to 5 degrees hotter than what the room temperature currently is.

If your heating hasn’t turned on within a few minutes, ensure it has juice by changing the fan switch from “auto” to “on.” If the fan doesn’t operate, your furnace might not have power.

Smart Thermostat

If you utilize a smart thermostat—for example one made by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting will depend on your model. Check the manufacturer’s website for assistance. If you’re still unable to get your Wi-Fi thermostat to function, call us at 903-284-2612 for heating and cooling service.

2. Inspect Breakers and Switches

Next, check if your breaker and furnace switch are on.

  • Look for your main electrical panel. If you have no idea where it is, keep an eye out for a silver metal box in your basement, garage or closet.
  • Make certain that your hands and feet aren’t wet before touching the panel or breakers.
  • Find the breaker marked “furnace” or “heat,” and make sure it’s switched “on.” If you find that the breaker tripped, it will be in the middle or “off” spot.
  • With one hand, steadily switch the breaker to the “on” position. If the breaker trips right away and pops back to “off,” don't try to reset it and call a professional from Goode Bros AC & Heating at 903-284-2612 immediately.

It doesn’t matter how old your furnace is or what brand it is, it has no less than one ordinary wall switch set on or near it.

  • Make certain the lever is facing up in the “on” spot. If it was shut off, expect your furnace to take up to five minutes to turn on. (If you don’t know where to locate your furnace, take a look at your basement, garage or utility closet. It might also be in a crawl space or attic.)

3. Put in a New Air Filter

When it comes to furnace issues, a grungy, full air filter is regularly the top offender.

If your filter is too grungy:

  • Your heating system won’t keep heating your home, or it may get too hot from restricted airflow.
  • Your gas bills could go up because your heater is turning on more often.
  • Your heat might fail prematurely since a dirty filter forces it to work harder.
  • Your furnace might be disconnected from power if an overly clogged filter results in a tripped breaker.

While it depends on what type of furnace you have, your air filter is located inside the blower compartment of your furnace, an attached filter case or wall-mounted return air grille.

To put in a new filter:

  • Turn off your heater.
  • Pull out the filter and hold it up to the light. If you can’t view light through it, get a new one.
  • Put in the new filter with the arrow motioning toward the heater to prevent damage.

Flat filters ought to be replaced once a month, while pleated filters should last about three months. If you have children or pets, you might have to put in a new filter sooner.

To make changing your filter easier in the future, write with a permanent writing tool on your heater outside or ductwork to list the airflow direction and filter size.

4. Examine the Condensate Pan

Otherwise known as drain pans, condensate pans catch moisture your heating system removes from the air.

If moisture is seeping out of your heater or its pan is overflowing, try these steps.

  • If your pan has a drain (look for a PVC pipe), check that it isn’t full. If it needs to be drained, get a special pan-cleaning tablet you can purchase at home improvement or hardware stores.
  • If your pan has a pump, take a look at the float switch. If the switch is stuck “up” with water in the pan, call us at 903-284-2612, because you will possibly have to buy a new pump.

5. Check for Furnace Error Codes

If faults persist, look at your heating system’s plastic window to verify the blower motor’s status. Subject to the type, the light might also be mounted on the surface of your heater.

If you see anything else besides a solid, colored light or flickering green light, contact us at 903-284-2612 for HVAC service. Your heater may be giving an error code that is calling for professional service.

6. Clean the Flame Sensor

If your heating system tries to operate but turns off without putting out heat, a grimy flame sensor could be at fault. When this occurs, your heating system will attempt to start three times before a safety device powers it down for about an hour.

If you feel okay with taking the panels off your heating system, brushing off your flame sensor is a job you have the ability to do on your own. Or, one of our heating service specialists can finish it for you.

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

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

As the next step:

  • Turn off the heating system’s power with its wall switch or breaker. If your furnace’s gas valve isn’t electric, you will need to turn off the gas as well.
  • Take off the furnace’s front panel and follow the wire to the flame sensor.
  • Take off the rod and use your sandpaper, steel wool or emery cloth to carefully clean the metal rod.
  • Wipe off the rod with a paper towel.
  • Remount the sensor.
  • Replace the furnace doors.
  • Turn the furnace’s power back on. It could run through a set of inspections before resuming usual running. If your heater doesn’t turn on, the sensor could require replacement or something else may be causing a problem. If this takes place, call us at 903-284-2612 for heating and cooling repair assistance.

7. Reignite the Pilot Light

If you are using an older furnace, the pilot light could be turned off. To reignite it, look for the guide on a label on your heater, or try these guidelines.

  • Locate the switch beneath your heater marked “pilot,” “on” and “off.”
  • Turn the switch to the “off” position.
  • Wait at least five minutes to prevent sparking a fire.
  • Push the knob to “pilot.”
  • Hold down the “reset” switch as you bring the flame of a long lighter to the pilot light opening.
  • Release the “reset” lever once the pilot light is lit.
  • If you have tried the guide twice and the pilot light still won’t ignite or remain lit, call us at 903-284-2612 for furnace service.

Examine Your Gas Source

Try switching on a second gas appliance. If it doesn’t function, your natural gas delivery could be switched off, or you could be out of propane.
