1. Introduction
This manual provides essential information for the safe and correct installation, operation, and maintenance of your Dometic Quick Thermocouple L25 (Part No. 2868877). A thermocouple is a critical safety device in gas appliances, designed to detect the presence of a flame. If the flame extinguishes, the thermocouple signals the gas valve to shut off the gas supply, preventing dangerous gas leaks. Please read these instructions thoroughly before installation and keep them for future reference.
2. Safety Information
- Professional Installation Recommended: Installation of gas appliance components should ideally be performed by a qualified service technician to ensure safety and proper function.
- Disconnect Power and Gas: Before attempting any installation or maintenance, always ensure the gas supply to the appliance is turned off and the appliance is disconnected from any electrical power source.
- Gas Leak Check: After installation, always perform a thorough gas leak check using a suitable leak detection solution. Never use an open flame to check for leaks.
- Use Original Parts: Only use genuine Dometic replacement parts to ensure compatibility and safety.
- Ventilation: Ensure adequate ventilation when working with gas appliances.

4. Installation / Setup
This section provides general guidance for replacing a thermocouple. Specific steps may vary depending on your appliance model. Refer to your appliance's service manual for detailed instructions.
- Preparation: Ensure the gas supply to the appliance is turned off and the appliance is disconnected from any electrical power. Allow the appliance to cool completely if it has been in use.
- Access: Carefully access the area where the thermocouple is located. This may involve removing cooktop grates, burner caps, or control panels.
- Locate Old Thermocouple: Identify the existing thermocouple. It is typically a metal rod or probe positioned near the burner flame, connected by a thin metal tube to the gas valve.
- Disconnect Old Thermocouple: Disconnect the thermocouple from the gas valve (usually a threaded connection) and carefully remove the probe from its mounting bracket near the burner.
- Install New Thermocouple: Insert the new Dometic Quick Thermocouple L25 probe into the mounting bracket, ensuring it is positioned correctly to be enveloped by the burner flame when lit. Connect the other end securely to the gas valve. Do not overtighten.
- Reassemble: Reassemble any removed parts of the appliance.
- Test for Leaks: Turn on the gas supply. Before lighting the burner, apply a gas leak detection solution to all connections made. Look for bubbles, which indicate a leak. If a leak is detected, turn off the gas immediately and tighten the connection. Repeat until no leaks are present.
- Functionality Test: Light the burner. The flame should heat the tip of the thermocouple. Hold the control knob in the 'on' position for a few seconds (as per your appliance's instructions) then release. The flame should remain lit. If it extinguishes, recheck the thermocouple's position and connection.

5. Operating Instructions
The Dometic Quick Thermocouple L25 operates passively as a safety sensor. When the burner is lit, the flame heats the tip of the thermocouple, generating a small electrical current. This current keeps the gas valve open, allowing gas to flow to the burner. If the flame goes out (e.g., due to a draft or boil-over), the thermocouple cools down, the electrical current stops, and the gas valve automatically closes, shutting off the gas supply to prevent unburnt gas from escaping.
No direct user interaction is required for the thermocouple's operation beyond ensuring it is correctly installed and functioning as part of the appliance's safety system.
6. Maintenance
- Regular Inspection: Periodically inspect the thermocouple for any signs of damage, corrosion, or carbon buildup.
- Cleaning: If carbon buildup is observed on the thermocouple tip, gently clean it with a soft brush or fine sandpaper. Ensure the tip is free from obstructions to allow proper flame contact.
- Replacement: If the thermocouple shows signs of damage, or if the burner repeatedly fails to stay lit after releasing the control knob, the thermocouple may need to be replaced.
7. Troubleshooting
- Burner Does Not Stay Lit:
- Ensure the thermocouple tip is directly in the flame path when the burner is lit.
- Check that the thermocouple connection to the gas valve is secure.
- Clean any carbon buildup from the thermocouple tip.
- If the issue persists, the thermocouple may be faulty and require replacement.
- Smell of Gas:
- Immediately turn off the gas supply to the appliance and ventilate the area.
- Do not operate any electrical switches or create any sparks.
- Check all gas connections for leaks using a leak detection solution.
- If the smell persists or the source of the leak cannot be identified, contact a qualified gas technician immediately.
