If your TEKA oven works on some settings but not others, the fault is usually more specific than it seems.
You turn the knob to fan oven — nothing. Switch to conventional — it works fine. Something inside is failing selectively.
This is a fairly common fault with TEKA ovens and in most cases points directly to a problem with how power is being distributed between functions.
So what's usually causing it?
1. Faulty selector switch
The selector switch controls which function receives power. Each setting uses a different internal contact — when one or more contacts fail, only the functions linked to working contacts will operate.
👉 Often the issue if:
- Specific settings work but others do nothing
- The grill works but fan oven doesn't, or vice versa
- The pattern of which settings work stays consistent
On Teka ovens, the selector switch is a highlighted fault point in repair guides specific to this brand. When individual contacts fail, certain programme positions stop responding while others continue working — Teka built-in models typically need to be pulled from their housing to access the switch from behind the control panel.
2. Wiring fault on a specific circuit
A loose or damaged wire on one particular circuit can cut power to a specific function without affecting others.
👉 More likely if:
- The fault appeared suddenly after moving the oven
- You can see or smell signs of burning near the back panel
- The affected setting has never worked since installation
3. Element failure on a specific function
Each cooking mode uses a different element. If one element fails, only the settings that rely on it will stop working.
👉 More likely if:
- The selector switch has been tested and is working
- You can see visible damage inside the oven cavity
- The fan runs but no heat is produced on that setting
If any of these situations apply to you, it's very likely that one of these parts needs replacing.
