Isolate the appliance before removing covers or panels for any reason. All tests for continuity should be carried out with a battery operated test meter only.
The most likely cause of overheating will be a failure of the thermostat contact points or sealed pressure system. In such a case you will need to fit a new compatible replacement unit.
Slow initial heating-up times or uneven heat distribution within the oven is usually caused by the failure of one element. Simple testing of the element will highlight the faulty item.
Failure to heat up at all may be either the thermostat or elements. As elements are the easier of the two to check for continuity, a simple process of elimination will indicate where the fault lies. Read the rest of this entry »
Throughout this post, references are made to meters and their use in continuity testing of individual parts of the appliances and their connecting wires. All testing and checking for ‘open’ (not allowing for current flow) or `closed’ circuit (allowing current to flow) must be carried out using a battery-powered multimeter or test meter. Testing should never be carried out on live items under any circumstances. Appliances must be disconnected from the mains supply. Read the rest of this entry »
