FAQ – Thermocouples

How do I know my thermocouple is defective?

If the throttle light on your gas goes off as soon as you release the hold button, it is likely that the thermocouple no longer detects the flame and should be replaced.

Can I use a universal thermocouple?

Yes, universal models are suitable for many domestic appliances. Just check the length and type of connector before order.

Is replacing a thermocouple complicated?

This is a simple operation: disconnect the old one, screw the new one and check the seal. If in doubt, call a professional.
