Oven and range maintenance: schedule, lifespan and costs
Updated
Overview
The oven and range, whether a single unit or a separate cooktop and wall oven, are among the simplest appliances in the house and among the longest lived. There's no pump, no water and no drain. The parts that fail are the ones that make heat and the ones that control it: a bake element or an igniter, a burner, a thermostat or a control board. The upkeep is cleaning, so grease doesn't build up where it can smoke or burn, and attention to a burner that's lighting slowly or an oven that's running off its set temperature.
Lifespan
An oven or range lasts 13 to 15 years. What shortens that is heat where it shouldn't be and grease where it can burn. A self-clean cycle run on a heavily soiled oven pushes the cabinet to its limits and is a known killer of control boards and thermal fuses on older units. Grease baked onto the elements and the burners shortens their lives and smokes every time the oven heats. Spills left on a cooktop corrode the burner caps and the igniters.
What extends the life is cleaning on schedule, a self-clean cycle used sparingly on an oven that's already mostly clean, and burner caps and grates washed before the spills carbonize. The signs an oven or range is near the end: a control board that fails or shows error codes, an oven that won't hold temperature after the thermostat and the element have been replaced, burners that won't light after new igniters, and an oven door that no longer seals because the hinges have worn.
Maintenance schedule
The one scheduled job, which keeps the rest from being needed.
| Task | How often |
|---|---|
| Clean the oven | every 3 to 6 months |
Alongside it, a few habits: wipe spills off the cooktop while it's still warm, wash the burner grates and caps when they're greasy, and check the oven's temperature now and then with a cheap oven thermometer, since the dial drifts over the years.
Replacement cost
A new oven or range costs $700 to $3,000. The low end is a basic freestanding electric range, and the high end is a large gas or dual-fuel range with convection, or a wall oven and cooktop bought as a pair. Installation is simple for an electric range that slides into the old spot, and a gas range needs a gas connection by someone who knows how.
The repair-or-replace rule: if the repair would cost more than half of a new unit and the range is past the middle of its lifespan, replace it. A control board on a range older than 13 years is often a replacement, since the part is expensive and sometimes no longer made. A bake element, a broil element, an igniter, a burner, a thermostat sensor or a door gasket is a repair, and the elements and igniters in particular are cheap parts that an owner can swap with a screwdriver.
Common problems
- The oven smokes when it preheats: grease and spills baked onto the floor and walls. Clean the oven.
- The oven heats slowly, or not at all: a failed bake element on an electric oven, or a failed igniter on a gas one. Both are visible on inspection and cheap to replace.
- Baking comes out uneven or burnt: the oven is running off its set temperature. Check it with an oven thermometer, and replace the temperature sensor if it's far off.
- A gas burner clicks but won't light: a wet or dirty igniter, or a burner cap that's not seated. Dry and clean the igniter and reseat the cap.
- An electric burner won't heat: the burner, the socket it plugs into, or the switch. Swapping a pair of burners of the same size shows which.
- The oven door won't close tight: a worn gasket or a sagging hinge, which lets heat out and runs the oven long.
FAQ
How long does an oven or range last?
About 13 to 15 years. Regular cleaning and a self-clean cycle used only on a mostly clean oven get it to the long end.
How much does a new range cost?
$700 to $3,000, from a basic electric range to a large gas or dual-fuel range with convection, or a wall oven and cooktop pair.
Is it worth repairing an oven?
Usually, since most oven faults are elements, igniters and sensors, which are cheap. A control board on a range older than 13 years is the exception.
Why is my oven not heating evenly?
The thermostat or temperature sensor has drifted, the element is failing on one side, or the door isn't sealing. An oven thermometer tells you how far off it is.
Is the self-clean cycle safe for the oven?
It's hard on it. The high heat can fail a thermal fuse or a control board, especially on an older oven. Use it on an oven that's already mostly clean, with the kitchen ventilated.
