1. Introduction
This document provides essential information regarding the De'Longhi Thermal Fuse TCO 157°C, an original replacement part designed for various De'Longhi electric oven models. A thermal fuse is a safety device that protects the oven from overheating by interrupting the electrical circuit if the temperature exceeds a safe limit. This guide covers safety precautions, compatibility, installation, and troubleshooting.
2. Safety Information
- Electrical Hazard: Always disconnect the oven from the main power supply before attempting any inspection, repair, or replacement of components. Failure to do so can result in electric shock, serious injury, or death.
- Professional Installation Recommended: Installation of electrical components should ideally be performed by a qualified technician. If you are not confident in your ability to safely replace this part, seek professional assistance.
- Original Parts: Use only original De'Longhi replacement parts to ensure proper function and safety.
- Temperature Rating: This thermal fuse is rated for 157°C. Ensure this matches the specifications required for your specific oven model.
3. Product Overview
The De'Longhi Thermal Fuse TCO 157°C is a critical safety component for your electric oven. It is designed to permanently break the electrical circuit if the internal temperature of the oven exceeds 157°C, preventing potential damage or fire hazards. Once activated, the fuse must be replaced.

- EO1835.A
- And many other De'Longhi electric oven models. Refer to your oven's service manual or identification plate for the exact part number.
5. Installation Instructions
Follow these steps carefully for the safe replacement of the thermal fuse. Remember to prioritize safety and disconnect power before starting.
- Disconnect Power: Unplug the oven from the wall outlet or switch off the circuit breaker supplying power to the oven. Verify that no power is reaching the appliance.
- Access the Fuse: Depending on your oven model, you may need to remove the back panel, top cover, or other access panels to locate the thermal fuse. Consult your oven's specific service manual for exact location.
- Identify the Fuse: The thermal fuse is typically a small, non-resettable component connected in series with the heating circuit. It may be housed in a protective sleeve or mounted directly to a metal surface.
- Remove Old Fuse: Carefully disconnect the electrical leads from the old thermal fuse. Note the orientation and connection points if necessary. Remove any mounting hardware.
- Install New Fuse: Mount the new De'Longhi Thermal Fuse TCO 157°C in the same location and orientation as the old one. Connect the electrical leads securely. Ensure all connections are tight and properly insulated.
- Reassemble Oven: Replace all access panels and screws that were removed. Ensure all components are securely fastened.
- Restore Power: Plug the oven back into the wall outlet or switch on the circuit breaker.
- Test Functionality: Turn on the oven and monitor its operation to ensure it heats correctly and safely. If the oven still does not function, proceed to the troubleshooting section.
6. Maintenance
Thermal fuses are designed as single-use safety devices. They are not user-serviceable and cannot be reset. If the thermal fuse has activated, it indicates an overheating event occurred, and the fuse must be replaced. Regular maintenance of your oven, such as cleaning and ensuring proper ventilation, can help prevent conditions that lead to thermal fuse activation.
7. Troubleshooting
If your oven still does not operate after replacing the thermal fuse, consider the following:
- Power Supply: Double-check that the oven is properly plugged in and the circuit breaker has not tripped.
- Other Faults: A blown thermal fuse often indicates an underlying issue that caused the oven to overheat. This could be a faulty thermostat, heating element, cooling fan, or control board. Replacing only the fuse without addressing the root cause may lead to repeated fuse failures.
- Incorrect Installation: Review the installation steps to ensure all connections are correct and secure.
- Professional Diagnosis: If the problem persists, it is strongly recommended to contact a qualified appliance repair technician for a thorough diagnosis and repair of the underlying issue.
