Quick Answer
Twelve simple habits — correct preheating, gentle cleaning methods, regular seal checks, and avoiding overloading the racks — can keep an oven performing well for fifteen or more years.
Most of these habits cost nothing and take only a few extra seconds per use of the oven.
An oven that's cared for properly can comfortably outlast one that isn't by many years. Here are twelve habits worth building into your routine.
12 Oven Care Tips
- Always preheat before cooking rather than starting cold
- Avoid lining the oven floor with foil, which can affect heat distribution
- Clean spills while the oven is still warm but not hot, before they bake on
- Use the self-clean function sparingly and as directed
- Avoid abrasive cleaners on the door seal
- Don't overload racks — allow space for heat to circulate
- Check the door seal periodically for gaps or wear
- Test temperature accuracy with an independent thermometer occasionally
- Don't slam the oven door, which can affect the seal and hinges over time
- Keep the exterior vents clear of dust and obstructions
- Book an annual professional service, especially for gas ovens
- Address unusual smells or uneven cooking early rather than ignoring them

Frequently Asked Questions
Does lining the oven floor with foil cause damage?▼
It can — foil can block heat distribution and, in some ovens, cause damage to the heating element if it touches it directly.
How often should oven temperature accuracy be checked?▼
Checking once or twice a year with an independent oven thermometer is a good habit, especially if you notice cooking results changing.
Is it bad to overload oven racks?▼
Yes — overcrowding restricts airflow, particularly in fan-forced ovens, leading to uneven cooking results.
Can these habits really extend an oven's lifespan to 15+ years?▼
Combined with an annual professional service, yes — most oven failures are accelerated by neglect rather than simple age alone.
