If you’ve ever searched for “Lennox furnace reset button,” “how to reset a Lennox furnace,” or “Lennox blower motor reset button location,” you know how intimidating it can be when your furnace stops working. Even though your home may have a Goodman MBVK electric furnace, understanding the principles behind furnace reset buttons, blower motor safeguards, and troubleshooting logic is universally helpful.
I’m Savvy Mavi, and in this guide, we’ll explore everything you need to know about Lennox furnace reset buttons, their locations, how to reset them safely, and why your system may need a reset. While the Goodman MBVK may not have a physical reset button, the underlying safety and diagnostic principles are the same.
What the Lennox Furnace Reset Button Does
The Lennox furnace reset button is designed as a safety feature. Its main purposes include:
-
Shutting down power to the furnace in unsafe conditions
-
Protecting the blower motor and heating elements
-
Preventing overheating or electrical damage
-
Allowing the system to restart safely once the fault is cleared
The blower motor reset button specifically protects the motor from damage due to overheating or electrical faults. Pressing the reset button manually restores operation after the issue has been resolved, but it’s important to identify the underlying cause before repeatedly pressing it.
Why You Might Need to Reset Your Lennox Furnace
Several situations can trigger a need to reset:
-
Overheated Blower Motor – Caused by airflow restrictions, dirty filters, or blocked vents.
-
Electrical Surges – Power fluctuations can trip safety mechanisms.
-
Control Board or Sensor Issues – Faulty sensors or boards may cause the system to lock out.
-
Short Cycling – If the furnace starts and stops frequently, it may need a reset to resume normal operation.
A reset is not a permanent fix; it is a diagnostic tool indicating that a deeper inspection may be required.
Lennox Furnace Reset Button Location
The reset button location varies by model:
-
Often found on the blower motor housing
-
Usually a small red or black button labeled “RESET”
-
On some models, it may be recessed behind a panel for safety
For general troubleshooting, consult your Lennox furnace manual, which provides precise location details. Even if you own a Goodman MBVK, understanding reset button placement helps you conceptualize safety interlocks and control logic.
How to Reset a Lennox Furnace
Here’s a safe, step-by-step approach:
-
Turn Off Power – Switch off the furnace at the breaker to prevent electrical hazards.
-
Locate the Reset Button – On the blower motor or control panel.
-
Inspect the Furnace – Check for airflow restrictions, dirty filters, or debris near the blower.
-
Press the Reset Button – Firmly press and release; do not hold it down.
-
Restore Power – Turn the breaker back on and set your thermostat to call for heat.
-
Observe Operation – Ensure the blower motor starts, elements energize, and the system cycles normally.
If the reset trips immediately, further inspection is required by a qualified technician.
Safety Considerations When Resetting
-
Always disconnect power at the breaker before pressing reset.
-
Avoid repeated pressing without addressing root causes.
-
Do not bypass safety features; the reset button is a protective mechanism.
-
If the furnace continues to trip, call a professional.
Even the Goodman MBVK electric furnace relies on similar interlocks and control logic, though resets may be electronic rather than a physical button.
Troubleshooting Lennox Furnace Reset Button Issues
If you experience repeated trips or the furnace doesn’t respond to a reset:
-
Check Airflow – Ensure vents are open and filters are clean.
-
Inspect the Blower Motor – Overheating or mechanical resistance can trigger trips.
-
Examine Electrical Connections – Loose or corroded wiring may cause intermittent faults.
-
Test Control Boards and Sensors – Faulty components may require professional diagnosis.
-
Observe Operating Patterns – Short cycling or uneven heat may indicate larger system issues.
Proper troubleshooting avoids damage to both the furnace and home wiring.
Comparing Lennox and Goodman MBVK Safety Logic
While the Goodman MBVK electric furnace may not have a manual reset button, it includes:
-
High-limit switches – Shut off heating elements if temperatures get too high
-
Blower interlocks – Ensure airflow before heating elements energize
-
Electronic diagnostics – Alerts for control board or sensor issues
Understanding Lennox reset logic helps owners of Goodman systems conceptualize how electric furnaces protect themselves, ensuring safe and efficient operation.
Maintenance Tips to Reduce Resets
-
Replace or clean air filters regularly
-
Keep vents unobstructed
-
Schedule annual furnace inspections
-
Monitor thermostat settings and ensure proper calibration
-
Clean blower assembly and ductwork
Regular maintenance reduces the likelihood of blower motor trips or reset button activation.
When to Call a Professional
Call a licensed HVAC technician if:
-
The reset button trips repeatedly
-
Heat output is inconsistent after a reset
-
Blower motor makes unusual noises
-
Breakers trip during furnace operation
-
The furnace is old or shows signs of component failure
Professionals can test wiring, control boards, and blower motors safely, ensuring long-term reliability.
Conclusion: Reset Buttons as a Diagnostic Tool
The Lennox furnace reset button—and by extension, blower motor reset features—are crucial safety devices. Knowing their location, function, and proper reset procedure empowers homeowners to handle minor issues safely and identify when professional service is needed.
Even if you own a Goodman MBVK electric furnace, understanding these principles helps you:
-
Interpret system shutdowns
-
Recognize when airflow or electrical issues exist
-
Safely restore furnace operation
-
Prevent damage to components
A reset button is never just a fix—it’s a signal that your system needs attention. Savvy furnace owners treat it as such, ensuring both safety and consistent home comfort.
