1. Look at the Thermostat
To start, ensure your thermostat is telling your heat to ignite.
- Swap out the batteries if the screen is blank. If the digital display is mixed up, the thermostat might need to be changed.
- Make sure the switch is switched to “heat” instead of “off” or “cool.”
- Make sure the program is showing the appropriate day and time and is set to “run.” If you’re having a hard time overriding the program, regulate the temperature with the up/down arrows and holding the “hold” button. This will cause the heater to turn on if thermostat scheduling is an issue.
- Increase the temperature setting to 5 degrees hotter than the room temperature.
If your furnace hasn’t kicked on within several minutes, make certain that it has juice by toggling the fan switch from “auto” to “on.” If the fan doesn’t start, your heater could be without power.
If you have a smart thermostat—like one designed by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting is very model-specific. Check the manufacturer’s website for support. If you aren’t able to get your Wi-Fi thermostat to work, reachl us at 862-345-6896 for heating and cooling service.
2. Examine Breakers and Switches
Next, you will need to verify your breaker and furnace switch are on.
- Find your home’s main electrical panel. If you have no idea where it is, look for a metallic metal box in your basement, garage or closet.
- Make certain that your hands and feet aren’t moist in advance of opening the panel or breakers.
- Locate the breaker titled “furnace” or “heat,” and ensure it’s moved to “on.” If you discover a tripped breaker, it will be in the middle or “off” position.
- Using one hand, firmly flip the breaker to the “on” spot. If the breaker trips right away and pops back to “off,” don’t try to reset it and get in touch with a team member from Willco Air Conditioning, Refrigeration & Heating Inc. at 862-345-6896 quickly.
No matter your furnace’s age or brand, it has at minimum one regular wall switch positioned on or near it.
- Make sure the control is flipped up in the “on” position. If it was shut off, it could take your furnace up to five minutes to turn on. (If you don’t know where your furnace is located, check your basement, garage or utility closet. It can also be in a crawl space or attic.)
3. Put in a New Air Filter
When we consider heating breakdowns, a dirty, clogged air filter is frequently the top offender.
If your filter is too dirty:
- Your heater won’t keep heating your home, or it might overheat from limited airflow.
- Your heating expenses might go up because your heat is working more often.
- Your furnace might fail too soon due to the fact a dusty filter causes it to work overtime.
- Your furnace may be cut off from power if an extremely filthy filter is the cause of a tripped breaker.
Based on what type of furnace you use, your air filter can be found in the interior of the blower compartment of your furnace, an attached filter case or wall-mounted return air grille.
To replace your filter:
- Cut the power to your heating system.
- Pull out the filter and hold it up to the light. If you can’t notice light through it, use a new one.
- Put in the new filter with the arrow motioning toward the heater to prevent damage.
Flat filters need to be replaced monthly, while pleated filters should be used for somewhere in the vicinity of three months. You may also get a washable filter that you can use for about 10 years. If you have children or pets, you might have to put in a new filter sooner.
To make the process smoother down the road, write with a permanent pen on your furnace housing or ductwork to indicate the airflow direction and filter size.
4. Check the Condensate Pan
Also known as drain pans, condensate pans hold moisture your heater pulls from the air.
If moisture is dripping from within your furnace or its pan has standing water in it, follow these steps.
- If your pan includes a drain (look for a PVC pipe), make sure that it isn’t clogged. If it should be drained, get a special pan-cleaning tablet you can get at home improvement or hardware shops.
- If your pan has a pump, take a look at the float switch. If the lever is jammed “up” with standing water in the pan, reach us at 862-345-6896, because you will probably have to buy a new pump.
5. Check for Furnace Error Codes
If failures continue, look inside your heating system’s plastic window to verify the blower motor’s status. Dependent on the type, the light could also be mounted on the surface of your furnace.
If you see anything other than a solid, colored light or twinkling green light, reach us at 862-345-6896 for HVAC service. Your heating system might be giving an error code that needs specialized assistance.
6. Clean the Flame Sensor
If your heating system tries to run but turns off without putting out warm air, a dusty flame sensor might be responsible. When this takes place, your furnace will make an attempt to turn on three times before a safety feature turns it off for approximately an hour.
If you feel confident with removing the panels from your furnace, brushing off your flame sensor is something you have the ability to do personally. Or, one of our heating service professionals is able to do it for you.
If you are confident cleaning the sensor on your own, you require:
- A 1/4” hex screwdriver or wrench
- Portion of light grit sandpaper, steel wool or emery cloth
- A dry, clean paper towel
- Shut off the furnace’s power through its wall switch or breaker. If your furnace’s gas valve isn’t electric, you have to switch off the gas in addition.
- Remove the heating system’s front panel and trace 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.
- Put the sensor back in.
- Secure the furnace doors.
- Restore power to the furnace. It might run through a set of tests before resuming regular operation. If your heating system doesn’t ignite, the sensor could require replacement or something else could be creating an issue. If this takes place, call us at 862-345-6896 for heating and cooling repair assistance.
7. Reignite the Pilot Light
If you have an older heating system, the pilot light could be out. To reignite it, locate the steps on a sheet on your heater, or try these guidelines.
- Locate the lever below your furnace labeled “pilot,” “on” and “off.”
- Push the switch to the “off” position.
- Wait at least five minutes to limit the possibility for sparking a fire.
- Move the dial to “pilot.”
- Press the “reset” button as you push the flame of a long lighter to the pilot light opening.
- Depress the “reset” lever once the pilot light is ignited.
If you have used the guide twice and the pilot light still won’t ignite or remain ignited, call us at 862-345-6896 for furnace service.
Examine Your Fuel Supply
Try switching on a second gas appliance. If it doesn’t work, your natural gas delivery could be switched off, or you could be out of propane.
