Oven light and fan work but the oven remains cold
The light is not evidence that the heating circuit is healthy. We inspect element continuity, selection controls, temperature feedback and the relevant wiring after safe isolation.
Defy cookers may combine oven heating, electric hotplates or gas burners in one appliance. Fault isolation starts by identifying which section is affected and whether the equipment uses electricity, gas or both.

Tell us what needs fixing. We'll contact you to discuss availability, diagnosis and next steps.
Defy cookers may combine oven heating, electric hotplates or gas burners in one appliance. Fault isolation starts by identifying which section is affected and whether the equipment uses electricity, gas or both.
If one plate is cold while the oven and other hotplates work, the fault may be local to that heating zone. If every section fails, supply or cooker-wide switching needs attention before multiple components are condemned.
An oven that lights up but remains cool illustrates why visual indicators are only part of the diagnosis. We consider selector functions, heating elements and control feedback. Tripping under heat is a separate electrical safety issue.

A single plate fault can involve its element, switch or terminals. If several plates fail together, we consider cooker supply and distribution before replacing individual components.
Oven door sealing, fan distribution, failed elements and thermostat behaviour can all affect temperature evenness. Testing actual heating response helps narrow the issue.
Ignition components, burner contamination, gas supply and flame supervision may require inspection. Gas-system adjustments and repairs must be performed by suitably qualified technicians.
The following information will help us plan the right assessment and confirm the nature of the fault without asking you to dismantle equipment.

We distinguish electric cooking faults from gas ignition and burner problems because their safety requirements are different. Do not keep testing a cooker with suspected leaking gas or a breaker that repeatedly trips.
The economical repair may be a replaceable control or element, but electrical damage or gas-system safety problems must be assessed in full. We explain the relevant safety checks and part compatibility before work proceeds.
A single electric plate that is cold may need its local heat control and element checked. A cooker with several dead functions needs examination of the incoming supply and switching arrangements first. An oven lamp can stay on while the heating circuit fails, so its operation is not confirmation that the element is receiving proper power. Tell us which modes work, whether the problem is intermittent and if a protective breaker trips when a particular function is selected.
A Defy cooker using both electricity and gas needs fault information for the exact section that is failing. Gas burner ignition and unstable flame issues demand gas-safety competence; electric oven tripping and failed hotplates require electrical isolation and testing. Do not adjust regulators or bypass protective controls yourself. If gas is suspected to be leaking, avoid switches and flames, ventilate where safe and seek immediate appropriate assistance. We will discuss routine service options only after the immediate risk has been addressed.
Practical answers before you arrange a repair enquiry in Pretoria or Centurion.
No. Heating circuits and control paths can fail independently of the light.
Gas components and connections should be handled only by appropriately qualified personnel following applicable requirements.
