Replacing an oven ranges from moderately easy (for standard plug-in units) to difficult and risky (for hardwired or gas units). A simple, like-for-like swap is an easy DIY, but hardwired electric or gas ovens require certified professionals.
If the oven uses a standard plug and meets local regulations, you might be able to install it yourself. However, hardwired ovens should always be installed by a qualified electrician.
Should I Repair or Replace my Oven? Oven repair costs range from $150 to $400, making repairs more affordable than replacement when your oven needs simple fixes or parts. You should replace your oven when repair costs exceed 50% of a new unit's value, especially if your appliance is over 15 years old.
New oven cost ranges from $750 to $3,000, with an average cost of $2,000. Prices vary based on oven type, size, fuel source, and installation requirements.
An electric oven typically lasts between 13 to 15 years, though high-end models can reach up to 20 years with proper care. Its longevity depends heavily on frequency of use, how often you clean it, and how well you maintain the internal heating elements.
When your oven is over 20 years old, you'll likely want to replace it when it needs a repair costing more than $500. After 20 years, replacement parts often start becoming scarce and the oven may continue to have failures as additional parts begin to wear out.
Incorrect temperature: Calibrate the oven or replace a faulty thermostat. Oven won't turn on: Check power, then seek professional help for electrical or gas issues. Broken oven light: Replace bulbs or consult a pro for wiring issues. Door issues: Handle stuck or misaligned doors with expert repairs.
You should start looking for a new oven if it requires frequent, costly repairs (the "50% rule" dictates replacing if a repair costs more than half the price of a new unit), shows signs of internal rusting, fails to reach or maintain temperatures consistently, or emits gas smells or strange odors.
Many folks go by the 50-50 rule. If the appliance has reached 50 percent of its expected life and it costs more than 50 percent of the cost of new, buy a new one. Oven failures can start with underperformance. For example, a family favorite just doesn't come out like it used to.
The sort of oven you own will determine how long it will last but in general, you should be looking around replacing yours before the 15 year mark: Electric Ovens: 13 - 15 years. Dual-Fuel Ovens: 15 years. Gas Ovens: 15 Years.
The Most Common Oven Repair Problems Homeowners Face
Temperature problems are another common warning sign. If your oven suddenly takes much longer to cook food or fails to reach the correct temperature, it could mean the thermostat or heating element isn't working properly. On the other hand, an oven that overheats can be even more dangerous.
First, check the user manual or specs online for your oven's electrical connection rating. If it says the oven uses more than 3kW, it will need to be hardwired. Some powerful double ovens, for example, have ratings up to 4.4kW and will absolutely need hardwiring.
This can be very dangerous, only a licensed electrician can complete this work safely. The team at NewAge Electrical can arrange safe installation of your new oven, including disconnecting and removing the old one and upgrading the electrical circuit and wiring if necessary.
You usually need an appliance repair engineer or a domestic electrician. Many faults (heating elements, thermostats, fans, control boards) are best handled by an appliance repair specialist, as they're trained to diagnose and repair specific oven components.
Holiday Sale Periods (May, September, and November)
Certain holidays have become synonymous with appliance discounts, and for good reason. Many shoppers wait for these times to make big purchases, and retailers respond with competitive pricing across most major brands.
Small appliances with the shortest lifespan typically include kitchen appliances like toasters, blenders, and coffee makers. These tend to have more limited warranties and are generally less durable compared to larger household appliances like refrigerators or washing machines.
Watch out for unsolicited "FINAL NOTICE" letters or aggressive sales tactics using scare language. Key indicators of a predatory plan or poor provider include vague contract terms, unverified company reviews, and arbitrary maintenance clauses used to deny claims.
The most reliable oven brands generally include GE Appliances (including GE Profile and Café), LG, and Bosch. These brands consistently score highest in customer satisfaction and require the fewest repair service calls compared to the industry average.
Here's what to watch out for.
About 8–12 years old: It depends on the specific issue, overall condition, and the cost of the repair. About 12–15+ years old: Replacement often makes more sense, especially if repairs are stacking up or performance is inconsistent.
Electric heating systems and tumble dryers tend to be the most expensive electrical items to run because they use large amounts of power over extended periods. Other high-cost appliances include electric ovens and immersion heaters.
The top 5 worst appliances to leave on standby
If your old cooker was installed many years ago, your kitchen's electrical circuit may not meet current safety regulations. For example, the engineer may need to install a new cooker circuit, upgrade the circuit breaker, or add a cooker switch. These additional electrical works can add £80 – £150 per hour to your bill.
