Thermador Induction Cooktop: not heating

Possible Causes

Cookware not positioned correctly or multiple items interfering

How to Identify: Cookware placed off-center or too close to other items, with the display not showing the correct cookware item.

Part: Cooktop sensing system

Power supply or connection issues

How to Identify: Cooktop not receiving full power; circuit breaker tripped; no power to the outlet.

Part: Electrical supply/circuit

Cooktop internal fault/error condition

How to Identify: Error codes shown on display, unresponsive controls, or shutdown behavior not linked to user actions.

DIY Solutions

Verify and Switch to Induction-Compatible Cookware

Easy 2-5 minutes

Tools Needed: magnet

1. Place a magnet on the bottom of your cookware.
2. If the magnet does not stick, switch to magnetic cookware suitable for induction.
3. Ensure the base is flat and of sufficient diameter for the zone (as recommended by Thermador).

⚠️ Safety First: Do not use cookware that does not make magnetic contact as the cooktop won’t heat.

Correct Cookware Placement

Easy 1-2 minutes

1. Center the cookware on the cooking zone.
2. Remove excess items from the surface if multiple pieces are too close.
3. Try switching positions if the display does not show the cookware on the intended zone.

Check Power Supply and Circuit Breaker

Moderate 5-10 minutes

1. Check that the cooktop is plugged in or correctly wired.
2. Check the circuit breaker for tripped switches and reset if necessary.
3. Verify the outlet is supplying power using another device.

⚠️ Safety First: Exercise caution when inspecting electrical panels.
