Oven not turning on: what our engineers find

Ovens

These figures come from NAC's own repair records: 171 oven jobs our engineers attended for this fault. Here is what they found, what fixed it and what it typically cost.

When an oven will not turn on, engineers sometimes find that nothing is wrong with the oven itself. Many ovens will not heat until the clock has been set, so after a power cut or a tripped fuse the display may light up while the oven does nothing. Engineers also sometimes find that the oven's own switch, often tucked away in a nearby cupboard, has been turned off by accident, or that the child lock has been left on, which on some self-cleaning ovens also keeps the door locked. Now and then the socket the oven plugs into has been damaged rather than the oven.

Where there is a genuine fault, engineers sometimes find a worn heating element that trips the electrics, a faulty door lock or main control board, worn door hinges that stop the door closing fully, or a failed selector switch, thermostat or fan motor.

An engineer will usually start by checking the power supply, the clock and the controls, then carry out electrical and safety tests on the parts inside. If a part has to be replaced, it often needs to be ordered and fitted at a second visit, after which the oven is heated and tested to make sure everything works properly.

About the price. £98 to £223 is the typical total paid by customers, including parts and VAT: the middle half of what customers paid on 76 of these repairs. Repairs paid for by manufacturers and insurers aren't counted, because that work is charged at contract rates. It's a guide, not a quote. Your engineer confirms a fixed price before any work starts.

Before you check anything yourself

  • Switch the oven off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
  • If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
  • If it's a gas appliance and you can smell gas, don't use it. Open the windows and call the National Gas Emergency Service on 0800 111 999.

A confirmed repair is a job we repaired where 60 days then passed with no engineer called back to it. Faults and causes are classified by an AI model reading our engineers' job notes, with personal details removed first, and checked against a hand-labelled sample of NAC jobs.
