Steps

Goal: Confirm the symptom, rule out power and controls, then check the LED strip or call a pro.

  • Plug in the fireplace and turn it on with the remote or onboard controls. If the power indicator is on but the flame LEDs stay off, the LED system has failed.
  • Good: Power or heat works but LEDs do not—proceed to Check power and controls.
  • Bad: Nothing works—check power first.

Check power and controls

Goal: Rule out power loss, remote, and mode settings before opening the unit.

  • Verify the fireplace is plugged in and the circuit breaker is on. Check the wall switch if present. Test the outlet with another device.
  • If the fireplace uses a remote, replace the batteries. Try the onboard controls (buttons on the unit) instead. Check that the flame mode or brightness is not set to off.
  • Good: Power and controls work—the LEDs light. See Verification.
  • Bad: Still no light—proceed to LED path.

LED path

Goal: Check the LED strip connection when power and controls are good but the LEDs still do not light.

  • Unplug the fireplace from the wall. Open the unit per your model. Check your owner’s manual or search “[brand] [model] fake fireplace service manual” for disassembly steps.
  • Locate the LED strip or flame light assembly. Check that the connector is firmly seated. A loose connection can prevent the LEDs from lighting.
  • If the connector is secure, the LED strip may have failed. Replace with a matching part (match the part number; appliance parts suppliers and the manufacturer sell replacements).
  • Good: You reconnected or replaced the LED strip. Reassemble and test—the flame should light.
  • Bad: The unit is sealed and you cannot access the LED strip, or you have checked everything and it still does not light—call a technician or replace the unit.

When to get help

Call 911 if you see sparks, smoke, or fire.

Call an appliance technician if:

  • The circuit breaker trips when you turn the fireplace on.
  • The unit is sealed and you cannot access the LED strip.
  • You have checked power, controls, and the LED connection and it still does not light.
  • You are not comfortable working with electrical components.

Fake fireplaces are often inexpensive—replacing the unit may be more practical than repair.

Verification

  • The flame LEDs light when you turn on the fireplace with the remote or onboard controls.
  • The flame effect appears as expected (flicker, color, brightness).
  • No flickering, buzzing, or burning smell.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm symptom Verify the fireplace does not light—power indicator may be on but flame LEDs stay off.
  2. Power and plug Check circuit breaker, GFCI, and that the plug is firmly seated.
  3. Remote and controls Replace remote batteries, try onboard controls, check flame mode and brightness.
  4. LED strip connection Unplug, open the unit, check the LED strip connector and wiring.
  5. Call a pro Sealed unit, all checks done and still no light, or not comfortable—call a technician or replace the unit.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Whether the power indicator (if present) is on
  • Remote or onboard controls only
  • Steps already tried
  • Model and brand

Does the fireplace respond at all—power light, heat, or LEDs?

Plug in the unit and try the remote or onboard controls. If nothing works, the fault is power. If power or heat works but LEDs do not, the LED system has failed.

Plug in the fireplace. Try the remote or onboard controls. Nothing works: proceed to check power. Power or heat works, LEDs do not: proceed to check controls and LED path.

Power/heat works, LEDs off No response

Is the circuit breaker on and the plug seated?

Power must reach the fireplace. Check the breaker and plug first.

Check the circuit breaker—reset if tripped. If GFCI outlet, press reset. Confirm the plug is firmly seated. Test the outlet with a lamp. Good: breaker on and plug seated. Bad: breaker keeps tripping or outlet dead—call an electrician.

Yes No

You can change your answer later.

Have you checked the remote, batteries, and mode setting?

Dead remote batteries or wrong mode can prevent the LEDs from lighting.

Replace remote batteries. Try the onboard controls instead of the remote. Check that the flame mode or brightness is not set to off. Good: controls work—LEDs light. Bad: still no light—proceed to LED strip.

Yes No

You can change your answer later.

Is the LED strip connection accessible?

The LED strip may have a loose connector or be failed. Unplug before opening.

Unplug the fireplace. Open the unit per your model. Locate the LED strip. Check that the connector is firmly seated. If loose, reconnect and test. If secure, the strip may have failed—replace with a matching part. Good: reconnected or replaced—LEDs light. Bad: unit is sealed or you cannot access—call a pro.

Yes No

You can change your answer later.

Fireplace is working

The flame LEDs light. No further action needed.

Call a technician

Call 911 if you see sparks, smoke, or fire. Call an appliance technician if the breaker trips, the unit is sealed and you cannot access the LED strip, or you are not comfortable with electrical repair. Fake fireplaces are often inexpensive—replacing may be more practical than repair.

Frequently asked questions

Why would a fake fireplace not light?
Common causes: power loss (tripped breaker, loose plug), dead remote batteries, wrong mode or brightness setting, loose LED strip connection, or failed LED strip. Check power and controls first, then the LED connection inside the unit.
Can I fix a fake fireplace that will not light myself?
Yes, for power checks, remote batteries, and mode settings. If the unit has accessible internals, you can check the LED strip connection. Sealed units or complex control boards usually need a technician or replacement. Always unplug before opening.
When should I call a technician for a fake fireplace?
Call an appliance technician if the unit is sealed and you cannot access the LED strip, if you have checked power and controls and the LEDs still do not light, or if you are not comfortable working with electrical components. Fake fireplaces are often inexpensive—replacing may be more practical than repair.
