If you’ve ever owned a gas or electric furnace, you’ve probably come across the phrase “furnace reset.” For homeowners of Rheem furnaces, this often involves finding the Rheem furnace reset button location, knowing how to press it, and understanding why the system needs resetting in the first place. Questions like “how to reset a Rheem furnace” are incredibly common during winter months when heat is critical, and frustration is high.
But what happens when you compare traditional furnaces like Rheem to modern electric systems like the Goodman MBVK electric furnace? The reset button isn’t just a button—it’s a safety mechanism, a signal, and sometimes a source of confusion. In this article, I’ll explain everything you need to know about resetting furnaces, walk through Rheem reset procedures, and show why the MBVK takes a different, simpler approach to furnace reliability.
What Is the Rheem Furnace Reset Button?
The Rheem furnace reset button is a safety feature designed to protect the furnace from repeated ignition failures. In most gas-powered furnaces, when the system attempts to ignite the burners and fails, it goes into a “lockout” mode. This prevents dangerous situations such as unburned fuel accumulation, delayed ignition, or damage to the furnace control board.
The reset button allows homeowners or service technicians to manually clear the lockout and attempt ignition again. But it’s important to note: this is not a solution to underlying problems—it’s a temporary override to restore operation while diagnosing the root cause.
Rheem Furnace Reset Button Location
Finding the Rheem furnace reset button location can be confusing, especially for first-time homeowners or those unfamiliar with furnace design. Typically, you’ll find the reset button:
-
Inside the burner access panel or near the blower compartment
-
On the primary control module or integrated circuit board
-
Sometimes labeled “RESET” and often colored red for visibility
The exact placement depends on the furnace model and year of manufacture. Older Rheem furnaces often have a prominent button near the gas valve, while newer models integrate it into the control module inside the main access panel. For reference, Rheem provides diagrams in the owner’s manual detailing reset button location and function (Rheem Furnace Support).
Knowing the location is critical, but it’s equally important to follow proper safety precautions before pressing the button.
How to Reset a Rheem Furnace Safely
When homeowners search “how to reset a Rheem furnace,” the general process is straightforward, but it should be performed with caution:
-
Turn off the furnace power using the service switch or breaker to ensure safety.
-
Wait a few minutes to allow any residual gas to dissipate.
-
Locate the reset button inside the furnace access panel.
-
Press the button once (do not hold it for more than a few seconds).
-
Restore power to the furnace and observe the ignition sequence.
After a reset, the furnace should attempt to ignite. If the burners light and the blower operates normally, the issue may have been a temporary ignition failure. However, repeated need for resets usually indicates a more serious problem, such as:
-
Dirty flame sensors
-
Faulty igniters
-
Gas pressure issues
-
Control board failures
Rheem provides detailed troubleshooting steps for persistent ignition issues (Rheem Furnace Troubleshooting Guide).
Why Resetting Isn’t a Long-Term Solution
While the reset button gets the furnace working again, it does not fix the underlying mechanical or electrical problem. Pressing the button repeatedly can actually:
-
Mask an ignition problem
-
Stress the control board or ignition components
-
Increase the risk of delayed ignition or burner failure
Professional inspection is always recommended if you find yourself pressing the reset button more than once or twice in a short period. A qualified technician can evaluate whether components like the flame sensor, igniter, or gas valve need replacement.
How the Goodman MBVK Electric Furnace Differs
Here’s where the comparison gets interesting. The Goodman MBVK electric furnace doesn’t use a flame, gas valve, or igniter. It produces heat entirely through electric resistance elements. That means the concept of a reset button for ignition simply doesn’t exist.
Instead, the MBVK includes:
-
High-limit safety switches to prevent overheating
-
Automatic blower control to manage airflow
-
Stage sequencing for electric heat strips
-
Diagnostic codes displayed via control board
Because there is no combustion, you don’t have to worry about flame failures, lockouts, or repeated resets. In other words, the MBVK eliminates an entire class of common furnace problems that homeowners encounter with gas furnaces like Rheem.
For detailed MBVK technical specs, see Goodman’s product resources (Goodman MBVK Product Page).
Benefits of the MBVK Over Traditional Gas Furnace Resets
When comparing a Rheem furnace with a manual reset button to a modern MBVK electric furnace, the advantages are clear:
-
Simpler Operation: No need to locate a reset button or troubleshoot igniters.
-
Increased Reliability: Electric elements are less likely to fail abruptly than gas ignition systems.
-
Lower Maintenance: No burners, flame sensors, or gas lines to clean and inspect.
-
Safer for Homeowners: No risk of delayed ignition, gas leaks, or carbon monoxide exposure.
Electric furnaces also integrate seamlessly with heat pumps, thermostats, and smart home systems, providing more control over indoor comfort.
Common Misconceptions About Furnace Resets
Many homeowners mistakenly believe that pressing the reset button fixes their furnace permanently. Some think holding the button longer will help, which is not true—over-holding can damage the control board. Others assume the reset button is only for emergency use, but in reality, repeated resets are a warning sign that professional service is needed.
In contrast, with the MBVK, if a high-limit switch or fault occurs, it’s automatically logged by the control board. Homeowners rarely need to intervene manually, which reduces risk and frustration.
Troubleshooting Tips for Rheem Furnace Reset Issues
If your Rheem furnace requires frequent resets, consider these steps:
-
Inspect the flame sensor and clean it if dirty.
-
Check the igniter for cracks or wear.
-
Ensure gas supply is uninterrupted and valves are fully open.
-
Observe airflow to confirm the blower is operating properly.
-
Evaluate control board codes for faults or lockouts.
Remember: repeated resets without addressing the underlying issue can lead to further damage or unsafe operation. For guidance on persistent problems, consult troubleshooting documentation (HVAC.com).
Why Switching to Electric Heat Eliminates Reset Worries
Homeowners tired of chasing reset buttons often ask me whether switching to electric heating is worth it. The MBVK provides a compelling solution:
-
No igniters or burners to fail
-
No lockouts to manually reset
-
Predictable, reliable heat every time you turn on the thermostat
-
Lower long-term service costs compared to gas furnace maintenance
From my experience, families in manufactured homes, tight condos, or areas without reliable gas service appreciate the peace of mind that comes with electric heat.
Installation and Compatibility Considerations
Installing a Goodman MBVK in place of an older gas furnace requires some planning:
-
Electrical service must support the MBVK’s kW rating
-
Duct sizing and airflow must match the furnace output
-
Blower and cabinet orientation should align with the existing space
While installation is straightforward for a qualified HVAC technician, homeowners appreciate that the MBVK doesn’t require gas connections, venting, or a reset button that might confuse them.
Final Thoughts from Mike Sanders
The Rheem furnace reset button serves a critical safety role in gas furnaces, but it’s also a reminder of the complexity and maintenance demands of combustion-based heating systems. Frequent use of the reset button is never a long-term solution—it signals underlying issues that require inspection.
Electric systems like the Goodman MBVK furnace take a different approach. By removing combustion from the equation, they eliminate the need for manual reset buttons entirely. That means fewer service calls, lower maintenance, and more predictable heat for homeowners.
Whether you’re replacing an aging gas furnace or upgrading a mobile home system, understanding how resets work—and why some modern systems don’t need them—is a key step toward reliable, safe, and comfortable heating.
