Furnace Repair Checklist
1. Inspect the Thermostat
First, ensure your thermostat is instructing your furnace to turn on.
- Replace the batteries if the monitor is blank. If the digital monitor is mixed up, the thermostat might need to be changed.
- Make sure the control is on “heat” as opposed to “off” or “cool.”
- Make sure the program is set to the right day and time and is programmed to “run.” If you’re having trouble turning off the schedule, 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 trouble.
- Set the temperature setting to 5 degrees above what the room temperature currently is.
If your heat hasn’t turned on within a few minutes, make certain that it has power by switching the fan switch from “auto” to “on.” If the fan doesn’t begin to run, your heating system could be without power.
If you have a smart thermostat—for example one made by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting will depend on your model. Take a look at the manufacturer’s website for help. If you’re still unable to get your Wi-Fi thermostat to work, contact us at 715-504-0533 for heating and cooling service.
2. Inspect Breakers and Switches
Next, verify your breaker and furnace switch are on.
- Find your main electrical panel. If you don’t know where it is, look for a silver metal box in your basement, garage or closet.
- Make sure your hands and feet aren’t moist prior to using the panel or breakers.
- Find the breaker labeled “furnace” or “heat,” and make sure it’s moved to “on.” If you discover a tripped breaker, it will be in the middle or “off” spot.
- Using one hand, quickly turn the breaker to the “on” position. If the breaker trips right away and pops back to “off,” don't try to reset it and contact an expert from Point Heating & Cooling at 715-504-0533 right away.
No matter your furnace’s age or brand, it has at minimum one standard wall switch situated on or close to it.
- Ensure the control is facing up in the “on” spot. If it was shut off, anticipate your furnace could take up to five minutes to start. (If you’re unsure where to find your furnace, look in your basement, garage or utility closet. It could also be in a crawl space or attic.)
3. Replace the Air Filter
When we think about furnace issues, a grungy, full air filter is often to blame.
If your filter is too dirty:
- Your heat won’t keep heating your home, or it could get too warm from restricted airflow.
- Your utility costs could increase because your heater is turning on too often.
- Your furnace might stop working prematurely due to the fact a dirty filter triggers it to work overtime.
- Your heating system may be cut off from power if an excessively clogged filter causes the breaker to trip.
Depending on what type of furnace you have, your air filter will be inside the blower compartment of your heater, an attached filter case or wall-mounted return air grille.
To put in a new filter:
- Cut the power to your heating system.
- Take out the filter and tilt it toward the light. If you can’t notice light through it, replace it.
- Put in the new filter with the arrow facing toward the furnace to avoid 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 replace your filter more often.
To make changing your filter go more quickly down the road, draw with a permanent marker on your heater exterior or ductwork to indicate the airflow direction and filter size.
4. Look at the Condensate Pan
Commonly known as drain pans, condensate pans capture water your furnace draws from the air.
If liquid is leaking from your heater or its pan has too much water in it, use these guidelines.
- If your pan contains a drain (look for a PVC pipe), make sure that it’s clear. If it requires draining, get a special pan-cleaning tablet you can purchase at home improvement or hardware retailers.
- If your pan contains a pump, take a look at the float switch. If the switch can’t be moved from the “up” position with standing water in the pan, contact us at 715-504-0533, because you will probably have to install a new pump.
5. Watch for Heater Error Codes
If failures keep on happening, look inside your furnace’s plastic window to confirm the blower motor’s status. Dependent on the type, the light may also be mounted on the surface of your heating system.
If you see anything else besides a solid, colored light or blinking green light, contact us at 715-504-0533 for HVAC service. Your furnace may be communicating an error code that needs professional help.
6. Brush off the Flame Sensor
If your furnace makes an effort to work but shuts off without distributing warm air, a filthy flame sensor can be to blame. When this takes place, your furnace will make an attempt to ignite three times before a safety feature shuts it down for around an hour.
If you feel comfortable with removing the panels from your heating system, brushing off your flame sensor is a task you can do personally. Or, one of our heating service specialists has the ability to finish it for you.
If you are fine with cleaning the sensor personally, you require:
- A 1/4” hex screwdriver or wrench
- Portion of light grit sandpaper, steel wool or emery cloth
- A fresh paper towel
- Disable the furnace’s power through its wall switch or breaker. If your gas valve isn’t electric, you must shut off the gas in addition.
- Take off the heater’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.
- Clear the rod with a paper towel.
- Put the sensor back in.
- Replace the furnace doors.
- Restore power to the furnace. It might proceed through a set of checks before resuming regular running. If your heating system doesn’t ignite, the sensor might need to be replaced or something else may be wrong. If this happens, get in touch with us at 715-504-0533 for heating and cooling repair support.
7. Relight the Pilot Light
If you are using an aging heater, the pilot light could be extinguished. To relight it, locate the instructions on a sticker on your heater, or use these steps.
- Find the toggle beneath your heating system that says “pilot,” “on” and “off.”
- Turn the switch to the “off” position.
- Wait at least five minutes to prevent starting a fire.
- Turn the knob to “pilot.”
- Press the “reset” button as you move the flame of a long lighter to the pilot light opening.
- Depress the “reset” switch once the pilot light is lit.
If you have gone through the guide twice and the pilot light still won’t burn or remain ignited, contact us at 715-504-0533 for furnace service.
Examine Your Energy Delivery System
Try turning on a second gas appliance. If it doesn’t function, your natural gas source may be turned off, or you may have run out of propane.
