Experiencing a furnace breakdown in the night can be a homeowner’s winter nightmare. The cold creeps in swiftly, comfort gives way to shivers, and the thought of waiting until morning for a repair can be daunting.
Sometimes, the solution to a furnace breakdown is straightforward and within your capacity to fix. Before you make that emergency call, work through the following simple checks.
If your furnace decides to take a nighttime hiatus, don’t panic—reach out to a reliable heating emergency services company in Colorado to bring back the warmth without delay.
Inspect the thermostat
Often, the culprit behind a furnace malfunction is as simple as incorrect thermostat settings. Ensure that your thermostat has been set to the “heat mode” and is set at a temperature higher than the room temperature. This can sometimes be overlooked, leading to an unnecessary emergency call.
Also, check if the thermostat’s batteries need replacement or if the device requires a reset. Thermostat malfunctions can mimic signs of a furnace failure, so confirming its proper operation is a critical first step in troubleshooting.
Check the circuit breaker
Circuit breakers protect your home against electrical overloads. They automatically cut off power when the system becomes strained. When your furnace stops working, checking the circuit breaker is essential.
A tripped breaker is easy to address by simply locating your electrical panel, finding the breaker labeled for the heating system, and ensuring it’s in the “On” position. If it tripped, flip it to “Off” and back to “On.”
This could very well resolve the problem and restore your furnace to working order. However, if the breaker trips repeatedly, this may indicate a more serious electrical issue, and it’s advisable to contact a professional.
Examine air filters
A blocked air filter can affect airflow, leading your furnace to work harder than necessary and, in some cases, triggering an automatic shutdown for safety reasons. It’s wise to routinely check and replace your furnace’s air filter, as this simple maintenance task can prevent unexpected shutdowns.
During a nighttime furnace failure, inspect the air filter and replace it with a new one if it’s visibly dirty or clogged. You might find that this quick fix is all that’s needed to get your furnace up and running again, bringing back warmth to your home and providing a temporary solution until a professional can conduct a more thorough inspection.
Look at the furnace switch
Just like any other electrical appliance, furnaces have a dedicated switch that can sometimes be accidentally turned off. This switch is usually located on or near the furnace and resembles a standard light switch. Verifying that this switch is in the “On” position is crucial.
An accidental bump or an uninformed family member might have turned it off, leading you to believe the furnace has a significant problem. By simply flipping this switch back on, you could potentially restore your furnace’s functionality and reinstate heat to your home during an otherwise chilly night.
If the switch is already in the “On” position, it could indicate a more serious issue, and it’s best to call a professional for assistance.
Observe the pilot light
The pilot light is a small burning flame that ignites the main burner. If this light goes out, the furnace cannot produce heat. Checking the pilot light in the event of a furnace malfunction during the night is a constructive step.
You’ll want to ensure that it is lit, and if not, follow the manufacturer’s instructions to re-ignite it safely. Sometimes, it could be a simple issue, such as a draft that has blown out the flame or a temporary loss of gas supply.
If the pilot light doesn’t stay lit, the problem might be a faulty thermocouple or a clogged pilot orifice, which will require professional service. Nonetheless, assessing the pilot light could offer a quick solution and provide immediate relief from the cold.
