How to Replace a Grill Element with a Built-in Thermostat Capillary

⚠️ SAFETY FIRST: IMPORTANT

Electricity can be lethal. Before attempting any repair, ensure the appliance is fully isolated from the mains power. If you are not confident using a multimeter or working with high-voltage components, consult a qualified engineer. Never work on a "live" circuit.

This is on the top upper oven on this twin cavity oven cooker model.

Not a hard job just 2 wires and 2 screw on this model and most models to be fair but this one does make it a bit more difficult that you have to open up the copper tube holding element and pull it out it can be hard to get the capillary tube out, try to open the copper out carefully and steady. Try not to damage capillary tube as you may cause damage and further expense and time on repair.

Does your top oven or grill only have two settings—"Cold" or "Burned"? Many dual-cavity hobs use a grill element with a capillary thermostat probe tucked inside a copper shroud. Replacing these is a bit more involved than a standard element. In this guide, I’ll show you how to swap it without damaging the delicate copper tube.

The "Golden Rule" for Capillary Tubes

The copper tube (capillary) is filled with a special gas or fluid. If you kink it or snap it, the thermostat will fail instantly, and the oven will either stay cold or run dangerously hot.

• Handle with care: Use long-nose pliers to gently open the copper shroud.

• No sharp bends: When threading the new probe in, keep the curves gradual.

Step-by-Step Replacement

1. Access the Rear: You’ll need to get to the back of the cooker to disconnect the wiring. Always isolate the power first!

2. Disconnect & Map: Pull the spade connectors off. Take a photo first so you know which wire goes to which terminal (usually two for power and one for earth).

3. The Probe Pull: Use your pliers to open the copper shroud inside the oven cavity and carefully slide the thermostat probe out.

4. The Front Screws: Open the door and remove the two screws holding the element to the oven roof. The element should now slide out.

5. Test the New Part: Before you screw everything back in, use your multimeter on the Ohms (Ω) setting to ensure the new element isn't a "dead on arrival" unit.

Remove the wiring but make not of what goes where so you return them back to

both retaining screws removed the element will just pull free 

Element is out you can test it with the multimeter again if you wish and test new on prior to fitting
