A furnace that will not turn on is one of the most frustrating problems a homeowner in Woods Cross can face, especially when temperatures begin to drop as summer fades. You expect the unit to kick on when the thermostat says it is time to heat things up, but instead, nothing happens. That silence can mean discomfort and stress for everyone in your home. Whether it is the middle of the night or early in the morning, having no heat can quickly turn into a serious issue when left unresolved.
It could be a simple fix or a sign of something more technical. Knowing the right steps to take when your furnace refuses to run is key to getting the situation under control quickly. Here is a simple breakdown of the most common causes and what you can check before reaching out for help. While some of these steps might diagnose an easy fix, others are best left to our professionals who handle furnace repair in Woods Cross every day.
Check the Thermostat
Start with the easiest step. If your furnace is not turning on, the thermostat may not be communicating properly with the system. Thermostats can be tricky because they are small devices that have a big job. One misstep in their settings or power supply can shut down your entire heating cycle.
Follow these points to check if the thermostat is set correctly:
– Make sure it is set to “heat,” not to “cool” or “off”
– Set the target temperature a few degrees higher than room temperature to trigger the furnace
– If your thermostat uses batteries, replace them with new ones and see if the display lights up or responds
One homeowner in Woods Cross thought their system was broken, but the actual cause was a set of nearly dead thermostat batteries that could not keep the signal strong. A quick battery swap had the furnace running again in minutes.
If your thermostat is unresponsive, the buttons do not work, or the screen is blank even after changing batteries, it could be a deeper issue such as wiring problems or internal failure. That is the right time to speak with our technicians for a full inspection.
Inspect the Power Supply
If the thermostat seems to be working fine, the next thing to check is the actual power to the furnace. A furnace that is not getting power cannot start at all, so it is important to find out if there is an electrical or switch-related issue.
Here is what you should look at:
– Confirm the switch near the furnace is turned on (this looks like a light switch)
– Check that the furnace is securely plugged in, if applicable
– Inspect your electrical breaker panel; furnace switches can trip and stop power from reaching the system
– See if any fuses are blown or breakers flipped; reset or replace them carefully if safe to do so
– Examine visible cords and wires for any signs of fraying, wear, or rodent damage
Never force a plug or adjust wires if you are unsure. A furnace with steady power will often hum faintly or have indicator lights on the control board. If there are no signs of power at all and none of the above steps help, that usually means it is time to bring in our professionals for a full check of the electrical components.
Examine the Furnace Filter
An overlooked but important part of your furnace system is the air filter. Dirty or clogged filters block airflow, putting stress on the unit and stopping it from igniting properly. If air cannot move through the system the right way, safety sensors can shut the furnace down to avoid damage.
A quick filter check should be part of your regular home routine and is definitely something to do if the furnace will not turn on. Here is what you can do:
– Locate your furnace filter panel and remove it carefully
– Inspect the filter against a light source; if you cannot see through it, it is too dirty
– Look for dust, pet hair, or debris buildup
– Replace disposable filters with the correct size and rating, usually found on the edge of the old filter
– Reinsert the new filter facing the correct direction (follow the arrow on the frame)
In Woods Cross, where dry conditions stir up more dust during certain times of year, homeowners often find that filters need changing more often than expected. One quick swap can make a big difference in performance.
If your furnace turns on briefly and shuts off again or will not start at all after a new filter is installed, there may be issues affecting airflow sensors or pressure switches from longer-term buildup. At that point, contact our technicians to evaluate internal parts that require professional handling.
Reset the Furnace System
Sometimes, a reset is all it takes to get a furnace running again. Modern systems have safety features that turn off the unit under abnormal conditions such as overheating, a power loss, blocked vents, or failed ignition cycles. The reset button can help restart things.
Follow these steps to reset the system safely:
1. Turn off power to the furnace at the breaker.
2. Locate the reset button. It is usually found inside the blower compartment or near the motor. Read your unit’s label or instructions when possible.
3. Wait at least 30 seconds with the power off.
4. Press the reset button once firmly. Do not hold it down or push it repeatedly.
5. Restore power and wait a few minutes to see if the system restarts.
Only use the reset once during troubleshooting. If it does not work, stop and do not keep pushing the reset. Multiple resets can damage internal components or disable safety mechanisms. That may point to deeper problems such as a malfunctioning ignition sensor or faulty gas valve. These types of problems should always be handled by our trained professionals who know how to service high-voltage and gas-powered equipment.
