Diagnostics
How a technician diagnoses it
Our technicians follow the factory diagnostic path for this fault.
- 1Identify which element is involved from the failing function. On the Elise/Mercury 48": the multifunction oven (left hand side) has THREE elements — top, base and fan element. The fan oven (right hand side) has ONE fan element. There is also a broiler element and a stirring fan.
- 2Access is from the rear: remove the right-hand rear cover (4 screws), the terminal cover (2 screws) and the left-hand wire cover (5 screws). This exposes the terminal box area, heating elements, circulation fans and thermostat phials.
- 3Measure element resistance and check for continuity to earth.
- 4On reassembly ensure all rear wiring is clear of the wire covers, then carry out earth bond and hi-pot electrical safety tests.
