As a fireplace technician with years of hands-on experience in diagnostics and repair, I’ve found that many electric fireplace malfunctions can be resolved with a simple reset. Issues like display glitches, no heat output, or persistent error codes often stem from safety triggers or brief power interruptions. Knowing how to reset the unit correctly not only restores normal function but also helps prevent unnecessary service calls. Most models come equipped with built-in reset mechanisms, and understanding how to safely access and use them can save time and ensure long-term performance. Most models have a reset function built in, and knowing how to use it can save you time, money, and stress.
Safety First
Unplug the Unit and Allow It to Cool
Before anything else, always unplug the fireplace from its power source. This prevents electrical hazards and ensures a safe reset process. Give the fireplace 5–15 minutes to cool down. This time helps dissipate any residual charge in the system and protects internal components from accidental damage during the reset.
Locating the Reset Mechanism
Built-in Reset Button or Switch
Some electric fireplaces come with a clearly labeled reset button. You might find it on the front control panel, near the main power switch, or inside a back or side access panel. If your unit includes one, this button is typically the quickest way to trigger a system reset.
Thermal Limit or Circuit Breaker
High-end models sometimes include a manual reset for the thermal safety shutoff system. These are usually hidden behind a panel and may require a firm press or switch flip to activate. Check your unit’s manual if you’re unsure where it’s located.
Step-by-Step Reset Process
Step 1: Power Off & Unplug
Turn off the fireplace completely, then unplug it from the wall outlet. Let it sit for 5–15 minutes to reset internal safety features and allow any built-up heat to disperse.
Step 2: Press or Flip the Reset
If your fireplace has a reset button, press and hold it for 5–10 seconds. If it uses a switch, flip it once and wait. This signals the control board to clear any stored faults.
Step 3: Reconnect Power
After waiting, plug the unit back in. Some models will restart automatically, while others may require you to press the power button or use the remote to turn it back on. At this point, your fireplace should return to normal operation.
Verification & Troubleshooting
Check Error Codes or Blinking Lights
Most resets clear error codes, but if lights keep blinking or codes reappear, the issue may be deeper. Refer to the fireplace manual for specific error descriptions.
Test All Fireplace Functions
Turn on the flame effect, adjust the heat setting, and test both the remote control and manual controls to confirm everything is working properly.
Inspect for Blockages or Faulty Components
Sometimes the root cause is physical. Clear dust from intake and exhaust vents, inspect power cords for wear, and make sure the thermostat setting is above room temperature so the heater will engage.

When to Call a Professional?
If your electric fireplace continues to show error messages, won’t heat, or remains unresponsive after a full reset, it’s time to call a technician. Persistent overheating, buzzing sounds, or electrical odors are signs of internal faults that need expert attention. According to repair expert Mia Langford,
“Repeated resets are a sign the fireplace is protecting itself; don’t ignore what your unit is trying to tell you.”
Conclusion
Resetting an electric fireplace is a simple but powerful fix. Unplug the unit, wait 5–15 minutes, press the reset, and reconnect power. In most cases, that’s all it takes. Keep your vents clear, monitor for repeated errors, and don’t hesitate to call a pro if the same issues keep returning. As heating expert Daniel Cruz puts it,
“A good reset restores function, but regular care prevents problems from starting in the first place.”
