If you’ve ever woken up to a cold house and found yourself muttering, “Why my furnace is not turning on?”—welcome to the club. I’ve been in more basements at 6 a.m. than I can count, standing next to homeowners wrapped in blankets, staring at a furnace that refuses to do its job.
Most of the time, that frustration starts with a familiar phrase: “My furnace will not turn on.” Sometimes it’s a gas furnace not turning on. Other times, the furnace does not turn on at all—no sound, no airflow, no heat. And when that happens, panic sets in fast.
Today, I want to talk about those exact situations—but through the lens of a system that avoids many of those problems altogether: the Goodman MBVK electric furnace.
We’ll talk about why furnaces fail to start, why gas systems are especially prone to shutdowns, and how electric furnaces like the MBVK are designed to be simpler, safer, and more reliable when temperatures drop.
This isn’t theory. This is field experience.
The Moment Every Homeowner Dreads
There’s a pattern I see every winter.
The thermostat is set correctly. The house is cold. You hear… nothing.
No blower.
No click.
No ignition.
Nothing.
That’s when the questions start rolling in:
-
Why my furnace is not turning on?
-
Is my furnace broken?
-
Is this going to cost me thousands?
If you’re dealing with a gas furnace not turning on, the list of possible causes is long—and often expensive. Gas systems rely on multiple components all working perfectly in sequence. One failure, and the entire system shuts down.
Electric furnaces like the Goodman MBVK operate differently, and understanding that difference is the key to avoiding a lot of winter headaches.
Why a Gas Furnace Will Not Turn On So Often
Let’s start with the elephant in the room.
When someone tells me “my furnace does not turn on,” nine times out of ten, they’re talking about a gas furnace. And there’s a reason for that.
Gas furnaces depend on:
-
A steady gas supply
-
An igniter or pilot light
-
Flame sensors
-
Pressure switches
-
Venting and exhaust systems
-
Safety lockouts
If any one of those components fails or reads unsafe conditions, the system shuts down. That’s by design—it’s about safety—but it also means more opportunities for failure.
The U.S. Department of Energy does a good job outlining the complexity of combustion-based heating systems and why safety controls are necessary, but complexity always comes with trade-offs.
“My Furnace Will Not Turn On”—What That Usually Means
When homeowners call me and say “my furnace will not turn on,” I walk them through a basic checklist before I ever roll a truck:
-
Is the thermostat calling for heat?
-
Is the breaker tripped?
-
Is the system showing any error codes?
-
Has the filter been changed recently?
With gas systems, even if all of that checks out, the furnace may still refuse to start due to internal safety shutdowns. A dirty flame sensor alone can stop a gas furnace dead in its tracks.
That’s one of the biggest reasons many homeowners are switching to electric furnaces like the Goodman MBVK.
The Goodman MBVK: A Different Kind of Reliability
The Goodman MBVK electric furnace doesn’t burn fuel. There’s no ignition sequence. No flame to prove. No exhaust to monitor.
Instead, it uses electric resistance heating elements, which dramatically simplifies the startup process.
When the thermostat calls for heat:
-
Power flows to the control board
-
Heating elements energize
-
The blower motor moves air
-
Warm air enters the duct system
That’s it.
Fewer moving parts. Fewer failure points. Fewer reasons for the furnace not turning on.

Why My Furnace Is Not Turning On: The Real Root Causes
Let’s talk honestly about the most common reasons furnaces fail to start, regardless of type.
Electrical Issues
Even gas furnaces rely on electricity. If there’s a tripped breaker, blown fuse, or loose connection, the furnace does not turn on—period.
Electric furnaces like the MBVK are fully electrical, but they’re also designed with clear diagnostics and fewer dependencies.
Safety Lockouts
Gas furnaces shut down if they detect anything unsafe—low airflow, improper combustion, blocked vents.
Electric furnaces don’t have combustion-related lockouts, which removes an entire category of startup failures.
Poor Maintenance
Dirty filters restrict airflow. Restricted airflow causes overheating. Overheating triggers shutdowns.
This applies to every furnace, but electric furnaces recover more gracefully once the issue is corrected.
The Psychological Toll of a Furnace That Will Not Turn On
This part doesn’t get talked about enough.
When your furnace will not turn on, it’s not just inconvenient—it’s stressful. You start worrying about frozen pipes, kids getting sick, emergency repair costs, and how fast the house is losing heat.
I’ve seen homeowners panic because their furnace does not turn on during a snowstorm, and they assume the worst.
One of the biggest advantages of electric furnaces like the MBVK is predictability. When something goes wrong, it’s usually electrical—and electrical problems are often faster and cheaper to diagnose.
Why Electric Furnaces Like the MBVK Are Simpler by Design
Simplicity is underrated.
Gas furnaces are mechanical, chemical, and electrical systems rolled into one. Electric furnaces are primarily electrical and mechanical.
That difference matters when it’s 10 degrees outside and your furnace is not turning on.
Electric furnaces:
-
Don’t need fuel delivery
-
Don’t require combustion air
-
Don’t produce exhaust gases
-
Don’t rely on flame detection
That means fewer reasons for the system to lock itself out.
The National Fire Protection Association has extensive research showing that heating equipment failures are often tied to combustion-related safety issues—another reason electric systems are gaining traction.
What Makes the Goodman MBVK Stand Out
The MBVK isn’t just an electric furnace—it’s a whole-home heating solution designed for real-world conditions.
Key features include:
-
Durable heating elements
-
Strong, consistent airflow
-
Compatibility with heat pumps
-
Quiet operation
-
Multiple built-in safety controls
Because it’s often paired with a heat pump, the MBVK also serves as backup heat, ensuring your home stays warm even when outdoor temperatures drop too low for efficient heat pump operation.
This hybrid setup dramatically reduces the chances of waking up to a house where the furnace does not turn on.
Gas Furnace Not Turning On vs. Electric Furnace Not Turning On
Let me be very clear here.
Any furnace can fail. But how it fails matters.
When a gas furnace is not turning on, the cause could be:
-
Gas supply interruption
-
Faulty igniter
-
Dirty flame sensor
-
Blocked venting
-
Pressure switch failure
When an electric furnace like the MBVK is not turning on, the cause is usually:
-
Electrical supply issue
-
Thermostat problem
-
Control board fault
That’s a much shorter list—and a much easier diagnostic process.
Cost, Downtime, and Peace of Mind
Here’s something most homeowners don’t consider.
When a gas furnace shuts down, it often requires specialized parts and safety checks. That can mean longer downtime and higher repair bills.
Electric furnaces typically use standardized electrical components. Repairs are faster. Parts are more readily available.
The Department of Energy’s heating system comparisons highlight how system complexity impacts maintenance and long-term reliability.
The Myth That Electric Furnaces Are “Weak”
I hear this all the time.
“Electric heat can’t keep up.”
“Electric furnaces are expensive to run.”
“Electric systems aren’t reliable.”
Those statements are outdated.
The Goodman MBVK delivers full heating capacity regardless of outdoor temperature. When paired with proper insulation and airflow, it provides consistent comfort even in cold climates.
And because there’s no combustion, there’s no risk of carbon monoxide—a safety advantage that simply can’t be ignored.
When Homeowners Ask the Right Question
Instead of asking “Why my furnace is not turning on?” I encourage homeowners to ask:
“What kind of furnace gives me the fewest reasons not to turn on in the first place?”
That’s where electric furnaces shine.
Maintenance That Actually Makes Sense
Electric furnaces don’t require:
-
Burner cleaning
-
Flame sensor replacement
-
Gas pressure testing
-
Vent inspections
Routine maintenance focuses on airflow and electrical integrity—things that are easy to monitor and address before they become emergencies.
That’s why systems like the MBVK tend to age gracefully.
Final Thoughts from Mike
If you’re tired of dealing with a furnace that will not turn on, or you’ve been burned—literally or financially—by a gas furnace not turning on at the worst possible moment, it may be time to rethink your options.
The Goodman MBVK electric furnace isn’t flashy. It’s not complicated. It doesn’t rely on fire to keep your family warm.
It just works.
And when winter hits, reliability isn’t a luxury—it’s the whole point.
Understanding why furnaces fail is important. Choosing a system designed to fail less often is even better.
That’s the difference electric heat makes.
