Furnace Repair Checklist

1. Check the Thermostat

First, ensure your thermostat is instructing your heat to start.

Digital Thermostat

  • Change the batteries if the screen is not displaying anything. If the digital screen is jumbled, the thermostat could need to be replaced.
  • Make certain that the control is on “heat” as opposed to “off” or “cool.”
  • Ensure the program is set to the correct day and time and is programmed to “run.” If you’re having problems getting out of the schedule, regulate the temperature by using the up/down arrows and holding the “hold” button. This will cause the furnace to start if thermostat is causing an issue.
  • Turn the temperature setting to 5 degrees hotter than the temperature of the room.

If your heating hasn’t started within a couple minutes, make certain that it has electricity by switching the fan switch from “auto” to “on.” If the fan doesn’t operate, your heating system could be without power.

Smart Thermostat

If you use a smart thermostat—like one designed by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting will depend on your model. Check the manufacturer’s website for help. If you’re still unable to get your Wi-Fi thermostat to function, reach us at 402-509-5940 for heating and cooling service.

2. Check Breakers and Switches

Next, confirm your breaker and furnace switch are on.

  • Look for your main electrical panel. If you have no idea where it is, search for a gray metal box in your basement, garage or closet.
  • Ensure your hands and feet are dry before opening the panel or breakers.
  • Look for the breaker labeled “furnace” or “heat,” and double-check it’s switched “on.” If the breaker has tripped, it will be in the middle or “off” area.
  • With one hand, quickly flip the breaker to the “on” position. If the breaker immediately trips and pops back to “off,” don't try to reset it and call a team member from Interstate Heating & Air Conditioning at 402-509-5940 right away.

It doesn’t matter how old your furnace is or what brand it is, it has at least one standard wall switch placed on or close to it.

  • Ensure the switch is moved up in the “on” position. If it was switched off, expect your furnace to take up to five minutes to turn on. (If you don’t know where your furnace is located, look in your basement, garage or utility closet. It could also be in a crawl space or attic.)

3. Buy a New Air Filter

When it comes to furnace breakdowns, a grungy, clogged air filter is often to blame.

If your filter is too dusty:

  • Your furnace won’t keep heating your home, or it might overheat from restricted airflow.
  • Your gas bills may go up because your furnace is turning on more than it should.
  • Your heating system might break down too soon because a dusty filter forces it to work harder.
  • Your heater might be disconnected from power if an excessively dirty filter causes the breaker to trip.

Based on what type of heater you own, your air filter can be found inside the blower compartment of your furnace, an attached filter case or wall-mounted return air grille.

To put in a new filter:

  • Cut the power to your furnace.
  • Pull out the filter and tilt it toward the light. If you can’t view light through it, use a new one.
  • Insert the new filter with the arrow pointing toward the heating system to avoid damage.

Flat filters should be replaced monthly, while pleated filters should last about three months. If you have children or pets, you may have to put in a new filter more frequently.

To make changing your filter smoother in the future, draw with a permanent writing tool on your heating system exterior or ductwork to list the airflow direction and filter size.

4. Check the Condensate Pan

Also known as drain pans, condensate pans capture moisture your heater pulls from the air.

If liquid is leaking from your furnace or its pan has standing water in it, try these steps.

  • If your pan contains a drain (look for a PVC pipe), check that it’s clear. If it requires draining, drop in a special pan-cleaning tablet you can get at home improvement or hardware retailers.
  • If your pan contains a pump, inspect the float switch. If the lever is stuck “up” with liquid in the pan, call us at 402-509-5940, because you will likely have to get a new pump.

5. Watch for Heater Error Codes

If failures keep on happening, peek within your heating system’s plastic window to confirm the blower motor’s status. Depending on the brand, the light could also be mounted on the outside of your furnace.

If you note anything other than a solid, colored light or flickering green light, contact us at 402-509-5940 for HVAC service. Your heater might be giving an error code that requires pro service.

6. Scrub the Flame Sensor

If your heater attempts to operate but switches off without distributing heated air, a dusty flame sensor can be to blame. When this takes place, your heater will attempt to turn on three times before a safety feature shuts it down for approximately an hour.

If you feel comfortable with opening up your heating system, gently scrubbing your flame sensor is a job you can do yourself. Or, one of our heating service professionals is able to do it for you.

If you want to clean 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
  • A dry, clean paper towel


  • Shut off the furnace’s power by using its wall switch or breaker. If you don’t have an electric gas valve, you have to switch off the gas along with it.
  • Take off the heating system’s front panel and follow the wire to the flame sensor.
  • Remove the rod and use your sandpaper, steel wool or emery cloth to carefully clean the metal rod.
  • Clear the rod with a paper towel.
  • Screw the sensor back in.
  • Put the furnace doors back on.
  • Switch the furnace’s power back on. It could run through a sequence of examinations before proceeding with regular operation. If your furnace doesn’t start, the sensor may require replacement or something else might be creating an issue. If this takes place, call us at 402-509-5940 for heating and cooling repair help.

7. Light the Pilot Light

If you are using an outdated heating system, the pilot light could be turned off. To light it, locate the guide on a label on your heater, or use these steps.

  • Find the switch below your heating system marked “pilot,” “on” and “off.”
  • Move the switch to the “off” position.
  • Take a break for at least five minutes to avoid starting a fire.
  • Turn the switch to “pilot.”
  • Hold down the “reset” button as you bring the flame of a long lighter to the pilot light opening.
  • Depress the “reset” button once the pilot light is lit.
  • If you have gone through the guide twice and the pilot light still won’t ignite or stay burning, call us at 402-509-5940 for furnace service.

Examine Your Gas Source

Try switching on a second gas appliance. If it doesn’t function, your natural gas source may be shut off, or you may have run out of propane.
