Our IQ500 oven thermometer failed 3 weeks after our warranty expired. The oven became inoperable. Siemens offered a service technician to visit a week later. The call out fee would be DKK1.395,00 plus parts. Warranty should exist to protect the company where necessary. Choosing to enforce the terms when a component fails just outside of warranty, but well within its useful lifetime does damage to the brand. In this case we are two parents to three children who will look elsewhere for our future white goods purchases.
