BRITANNIA oven not heating up – what could be the problem?

It’s one of the most frustrating problems. Your BRITANNIA oven may seem to be working — the fan is spinning, the light may be on — but there’s no heat at all.

You leave it on, wait… and nothing cooks.

This is a common issue with Britannia ovens, and in many cases it can be fixed without replacing the whole appliance.

So what’s usually causing it?

1. Faulty selector switch

This controls where power is sent inside the oven. If it fails, the oven can appear to be working, but the heating elements won’t receive power.

👉 Often the issue if:

• The oven works in some settings but not others
• The grill works but the oven doesn’t
• The issue is inconsistent

On Britannia range cookers, a fan running with no heat is a well-documented fault on models such as the SI-106T and SI-9TV series. The multi-position selector switch can develop burnt or failed oven contacts that cut power to the heating element while the fan, light and thermostat indicator continue to operate as normal.

2. Broken heating element

This is the part responsible for generating heat inside the oven.

👉 More likely if:

• The oven doesn’t heat at all in any setting
• You noticed weaker heating before it stopped
• Sometimes visible damage or no glow

3. Thermostat issue

This controls and regulates the oven temperature.

👉 More likely if:

• The oven heats but not consistently
• Food comes out undercooked or uneven
• The temperature feels unstable

If any of these situations apply to you, it’s very likely that one of these parts needs replacing.
