Furnace Repair in Newark, OH

To begin, make sure your thermostat is instructing your furnace to turn on.

Swap out the batteries if the screen is blank. If the digital screen is jumbled, the thermostat may need to be replaced.

Make sure the switch is set to “heat” rather than “off” or “cool.”

Ensure the program is showing the correct day and time and is set to “run.” If you’re having a hard time overriding the program, set the temperature by using the up/down arrows and press the “hold” button. This will make the furnace to ignite if thermostat programming is causing a problem.

Increase the temperature setting to 5 degrees warmer than the room temperature.

If your furnace hasn’t kicked on within several minutes, make sure it has power by toggling the fan switch from “auto” to “on.” If the fan doesn’t begin to run, your furnace could be without power.

If you have a smart thermostat—like one made by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting is very model-specific. Take a look at the manufacturer’s website for help. If you still can’t get your Wi-Fi thermostat to work, call us at 740-344-5497 for heating and cooling service.

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

Look for your house’s main electrical panel. If you don’t know where it is, search for a gray metal box in your basement, garage or closet.

Make sure your hands and feet are dry before touching the panel or breakers.

Find the breaker labeled “furnace” or “heat,” and make sure it’s switched “on.” If the breaker has tripped, it will be in the middle or “off” position.

Using one hand, firmly switch 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 professional from Luikart Heating & Cooling at 740-344-5497 right away.

No matter your furnace’s age or brand, it has at least one standard wall switch located on or near it.

Make sure the switch is flipped up in the “on” position. If it was turned off, anticipate your furnace could take up to five minutes to turn on. (If you don’t know where to find your furnace, take a look at your basement, garage or utility closet. It could also be in a crawl space or attic.)

When it comes to furnace breakdown, a filthy, clogged air filter is frequently to blame.

If your filter is too dirty:

• Your furnace won’t be able to stay on, or it could overheat from limited airflow.
• Your energy bills could be higher because your furnace is turning on too often.
• Your furnace could stop working too soon because a dirty filter causes it to overwork.
• Your furnace can be disconnected from power if an excessively dirty filter causes the breaker to trip.

Depending on what make 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 replace your filter:

1. Turn off your furnace.
2. Take out the filter and hold it up to the light. If you can’t see light through it, replace it.
3. Insert the new filter with the arrow pointing toward the furnace to avoid damage.

Flat filters should be replaced once a month, while pleated filters should last about three months. You can also get a washable filter that will last about 10 years. If you have children or pets, you may have to change your filter more often.

To make the process easier in the future, use a permanent marker on your furnace housing or ductwork to show the airflow direction and filter size.

Commonly known as drain pans, condensate pans catch water your furnace pulls from the air.

If water is dripping out of your furnace or its pan has standing water in it, follow 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, use a special pan-cleaning tablet you can get at home improvement or hardware stores.
• If your pan contains a pump, take a look at the float switch. If the switch is stuck “up” with standing water in the pan, contact us at 740-344-5497, because you will probably need a new pump.

If malfunctions continue, take a look inside your furnace’s plastic window to verify the status of the blower motor. Depending on the model, the light could also be attached on the outside of your furnace.

If you see anything other than a steady, colored light or blinking green light, call us at 740-344-5497 for HVAC service. Your furnace may be emitting an error code that needs professional help.

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

If you feel comfortable with opening up your furnace, cleaning your flame sensor is something you can do by yourself. Or, one of our heating service specialists can do it for you.

If you want to clean the sensor yourself, you’ll need:

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

Next:

• Shut off the furnace’s power by using its wall switch or breaker. If your gas valve is not electric, you will need to shut off the gas as well.
• Lift off the furnace’s front panel and follow the wire to the flame sensor.
• Unscrew the rod and use your sandpaper, steel wool or emery cloth to gently rub 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 might proceed through a set of checks before proceeding with regular operation. If your furnace doesn’t ignite, the sensor may need to be replaced or something else might be wrong. If this happens, call us at 740-344-5497 for heating and cooling repair assistance.

If you own an older furnace, the pilot light could be out. To relight it, find the instructions on a label on your furnace, or follow these steps.

• Look for the switch on the bottom of your furnace labeled “pilot,” “on” and “off.”
• Turn the switch to the “off” position.
• Wait at least five minutes to avoid possibly sparking a fire.
• Turn the knob to “pilot.”
• Press the “reset” button as you bring the flame of a long lighter to the pilot light opening.
• Release the “reset” button once the pilot light is lit.

If you have followed the instructions twice and the pilot light still won’t light or stay lit, contact us at 740-344-5497 for furnace service.

Try turning on another gas appliance. If it doesn’t work, your natural gas service could be turned off, or you could be out of propane.
