Why does the circuit breaker trip when I turn on my Dimplex Indoor Fireplace?
- S
  Sue FosterAug 18, 2025
  If the circuit breaker trips or a fuse blows when you turn on your Dimplex Indoor Fireplace, it could be due to two main reasons. First, the current rating of the circuit breaker or fuse might be exceeded by the combined power draw of the fireplace and other appliances on the same circuit. Try plugging the unit into another outlet or installing it on a dedicated 15 amp circuit. Second, there might be a short in the unit's wiring, in which case you should trace the wiring in the unit.

This document provides a comprehensive service manual for Dimplex electric fireboxes, covering various models including XHD23L/XHD23G, XHD26L/XHD26G, XHD28L/XHD28G, XHD33L/XHD33G, and DF26L-PRO, DF26DWC-PRO, DF28L-PRO, DF28DWC-PRO. It outlines the function, usage, and maintenance features of these devices, emphasizing safety and proper handling.

The Dimplex electric fireboxes are designed to provide the ambiance of a traditional fireplace without the need for venting or fuel. They feature realistic flame effects and, in some models, a heating function to supplement room warmth. The devices are operated via a main control board, which manages various components such as the heater, flicker motor, flame LED strip, and log set or media bed LEDs. Some models also include a touchpad for user interaction and a remote control for convenient operation.

Function Description:

The primary function of these Dimplex electric fireboxes is to create a realistic fireplace experience. This is achieved through several integrated components:

Flame Effect: A flicker motor, combined with flame LED strips and a reflective surface, generates a dynamic and lifelike flame effect. The intensity and movement of the flames can often be adjusted to suit user preference.
Heating (Optional): Many models incorporate a heater assembly that provides supplemental heat to a room. This feature can be turned on or off independently of the flame effect, allowing for year-round enjoyment. A thermistor monitors the temperature to prevent overheating and ensure safe operation.
Log Set/Media Bed: Depending on the model, the firebox includes either a realistic log set or a media bed (such as crushed glass or ice chunks) illuminated by LEDs. These elements enhance the visual appeal and contribute to the authentic fireplace look.
Control System: A main control board acts as the central hub for all functions. It receives commands from the touchpad or remote control and activates the relevant components. This board also includes safety features to prevent malfunctions.

Usage Features:

The Dimplex electric fireboxes are designed for ease of use and offer several features to enhance the user experience:

Intuitive Controls: Models with a touchpad provide a user-friendly interface for adjusting settings such as flame brightness, heat output, and timer functions. Remote controls offer added convenience, allowing users to operate the firebox from a distance.
Independent Operation: The flame effect and heating function can typically be operated independently. This means users can enjoy the visual ambiance of a fire without heat during warmer months, or use the heater alone if desired.
Adjustable Settings: Users can often customize the flame brightness and, in some models, the speed of the flicker effect to create their desired atmosphere. The heater may also have multiple heat settings.
Safety Features: Built-in safety mechanisms, such as a thermistor to prevent overheating and automatic shut-off functions, ensure safe operation. Users are advised to allow at least 10 minutes for the heating elements to cool off to avoid accidental burning of skin when servicing.
Easy Installation: The fireboxes are designed for straightforward installation into a mantel or wall opening. The manual provides detailed instructions for accessing and removing components for maintenance or repair.

Maintenance Features:

Regular maintenance is crucial for ensuring the longevity and optimal performance of the Dimplex electric fireboxes. The manual provides detailed instructions for various maintenance tasks and component replacements:

Accessing Components: The top panel and bottom panel of the firebox can be removed to gain access to internal components such as the main control board, heater assembly, flicker motor, and LED strips. Specific instructions are provided for each model to ensure safe and proper access.
Component Replacement: The manual includes exploded parts diagrams and replacement parts lists for various models, making it easy to identify and order specific components. Instructions are provided for replacing:
- Heater Assembly: If the heater is not turning on or cutting out after a short time, the heater assembly may need replacement.
- Power Supply: Issues with the power cord or the device not turning on may indicate a faulty power supply.

- Flame Base LED Strip: Similar to the flame LED strip, issues with the flame base LED strip can affect the overall illumination of the firebox.
- Media Tray / Media LED Strip: For models with media beds, issues with illumination may require replacement of the media LED strip.
- Log Set: If the log set is not glowing or is positioned improperly, it may need adjustment or replacement.
- Remote Control: If the remote control is not functioning, it may need to be replaced or its batteries checked.
Wiring Diagrams: Comprehensive wiring diagrams are provided for different models, which are essential for troubleshooting electrical issues and ensuring correct reassembly after maintenance.
Troubleshooting Guide: A detailed troubleshooting guide helps users diagnose common problems based on symptoms, providing potential causes and solutions. This covers issues such as circuit breaker trips, power cord warmth, firebox not turning on, unresponsive remote control, and problems with flame effects or heating.
Safety Precautions: Throughout the maintenance sections, warnings are given regarding disconnecting power before attempting any maintenance to reduce the risk of electric shock or injury to persons. Users are advised to allow heating elements to cool down before handling.
