Electric cookers are among the most widely used cooking appliances in Nairobi homes and apartments. They are clean, consistent, and straightforward to operate. At Cooker Repair, we repair electric cookers daily and understand their faults inside out. Here is your guide to how they work and what goes wrong.
How an Electric Cooker Works
An electric cooker converts electrical energy into heat through resistance. On the hob, this happens via solid hotplates — cast iron rings with embedded resistive coils — or, in more modern models, ceramic glass surfaces with radiant elements underneath.
When you select a heat setting, you are adjusting how much electrical current flows through the element. Higher current means more heat. On traditional solid plate hobs, the heat builds gradually and retains warmth after switching off. On sealed plate or radiant hobs, the surface glows red when hot.
In the oven cavity, two separate elements handle different functions. The lower element is the primary baking element, while the upper element serves as the grill. A thermostat senses the oven’s internal temperature and switches the lower element on and off to maintain your chosen setting. A selector switch lets you choose between oven-only, grill-only, or combined functions.
Key components include: hob heating elements or hotplates, the oven baking element, the grill element, the thermostat, the selector switch, control knobs, the door seal, and the oven lamp.

Efficiency and Safety
A faulty element on an electric cooker often goes unnoticed at first — you may simply think the cooker is a bit slow before realising a ring has partially failed. Meanwhile, a malfunctioning thermostat silently drives up your electricity bill while under or overcoating your food. Early repair pays for itself.
