Start with a diagnosis, not an age rule. Repair may make sense when the failed part is available and the appliance can be restored within its installation limits.
Replacement brings fit, clearance, power or fuel requirements and removal and installation work. Warranty terms can differ by product and by who performs the work, so compare them before deciding.
Identify the appliance model and the symptom. A clear photo of the model label can help you record details for the request.
