The Bosch engineer who changed the lamp in our microwave also pointed out a large capacitor that should he checked was completely discharged by putting a heavily insulated pair of pliers across it. I imagine if you left one off for a day or so that would also be safe but I would still do the plier trick.

I thought it a daft design that the bulb couldn't simply be replaced from the outside once the outer casing was off. But maybe it has to be that way to keep emissions to the minimum.

Most microwave ovens seem to be designed that was Gary.

We used to have a Neff and I replaced it with a Siemens (Neff/Bosch/Siemens - same outfit). On neither of them could you replaced the bulb without removing the microwave and stripping it down, unlike conventional ovens which usually have a removable glass cover. I think the upshot is that they don't want non-technical householders replacing microwave oven bulbs as perhaps they might not replace the screening grille correctly.

When I came to replace the built-in oven and microwave which became unreliable after 20 years, I switched off the cooker isolator box only to find it was still live. On investigation, the electrician who wire up the house when newly built, had for some inexplicable reason, wired it incorrectly so that whether the switch was on or off, the appliances were still live. So much for 'professionals'. I had to switch off at the consumer unit and re-wire the cooker isolating switch before I fitted the ovens.

Our microwave gets used 4 minutes a day to cook my breakfast porridge - our NEF dishwasher built-in when the house was built has never been used in 23 years. More trouble than washing up!
