Range cooker oven not heating: what our engineers find

Range Cookers

These figures come from NAC's own repair records: 219 range cooker jobs our engineers attended for this fault. Here is what they found, what fixed it and what it typically cost.

When a range cooker oven stops heating, the cause our engineers find most often is a failed fan oven element, the circular heater behind the fan at the back of the oven. The fan may still turn while the oven stays cold on the fan setting, and other settings or the other oven may carry on working. Quite often the element fails with a trip of the household electrics, after which the oven no longer warms up.

To find the fault, the engineer carries out electrical safety checks, tests each heating element in turn and confirms that power is reaching the fan element. Once the element is shown to have failed, it is replaced and the oven is run up to temperature to make sure it heats as it should. Engineers sometimes also find a slow or faulty fan motor, or worn elements in the smaller oven, and replace those too.

The right element is not always carried on the van, so it often has to be ordered and fitted at a second visit. Engineers sometimes find the oven isn't faulty at all, because on some cookers the clock must be set before the oven will heat.

Why the first-appointment figure differs by brand. Our engineers carry common parts on the van, so those repairs can be finished at the first appointment. Other parts have to be ordered in, and fitting them takes a second visit.

About the price. £165 to £266 is the typical total paid by customers, including parts and VAT: the middle half of what customers paid on 169 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 range cooker 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.
