HAIER Oven Works on Some Settings But Not Others – Reason & Fix

If your HAIER 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 grill — it works fine. Something inside is failing selectively.

This is a fairly common fault with HAIER 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 Haier ovens, the selector switch is mounted behind the front fascia and controls power distribution across all cooking functions. When individual contacts degrade, they cause specific settings to fail while leaving others fully operational — a fault pattern that points directly to the switch before any other component is considered.

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.
