Step-by-Step Fix

Safety & Preparation

Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).

  1. Before you start, always switch off the cooker at the mains isolation switch or pull the plug from the wall socket for safety. Then, check the circuit breaker or fuse box to ensure the cooker's dedicated circuit hasn't tripped; reset it if necessary, or replace a blown fuse in the plug.
  2. With the power safely isolated, carefully inspect all visible heating elements in the oven and on the hob for any signs of damage like breaks or discolouration. If an element appears faulty, or if specific zones aren't heating up, this suggests a localised element failure that will require replacement.
  3. Check if the oven light or display is working; if not, ensure the timer and function selectors are correctly set as per your manual. For temperature issues, try setting the oven to a moderate temperature and listen for the thermostat clicking on and off, which indicates it's attempting to regulate heat.
  4. Examine the oven door seal around the entire perimeter of the door for any gaps, tears, hardening, or loose sections. A damaged or worn seal can allow heat to escape, leading to inefficient cooking and increased energy consumption, so it should be replaced if faulty.
  5. If you've followed these steps and the problem persists, or if you feel uncomfortable performing any of these checks, it's safest to contact a qualified appliance technician. They have the specialist tools and expertise to diagnose and safely repair more complex internal faults.
