Typically oven stoves should last between 10 and 15 years, so if your oven is more than 15 years old, now might be an appropriate time to consider a full oven replacement. Repair is always an option, until repairs cost more than the oven is worth. If the oven breaks down constantly, it may mean that the unit is reaching the point of no return. Ongoing replacement of parts and paying for repairs can add up quickly, so buying a new furnace would make more financial sense.
Plus, you won't waste time waiting for the technician. Stoves usually last about 15 years, although they can last longer if you have a gas stove. It's quite easy to know when the stove needs to be replaced, as it will stop heating evenly and you may have difficulty cooking food. You shouldn't take any risks when it comes to your stove, as it can be dangerous.
In general, ovens can last about fifteen years before they need to be replaced. So, if your range is younger than that, you can wait to buy a new one. However, anything older than fifteen will need to be replaced. The best ovens will last for years, approximately 15-20 years.
If your oven suffers from one problem after another, you've been consulted with a professional repair company and they've confirmed that it can't be repaired, then it's time to consider replacing it. This applies to both gas and electric stoves. Knowing when to repair and replace your appliances can prevent you from being stranded without them when you need them. However, at some point, there is an important line between an appliance that can be repaired and one that needs to be replaced.
