If "the operating noise" is the cooling fan for the magnetron, it keeps going when the time is up to cool it down. Mine does the same, but actually says "COOL"

If "the operating noise" is the cooling fan for the magnetron, it keeps going when the time is up to cool it down. Mine does the same, but actually says "COOL" on the screen when it does so.
- thaumasiotes 4y agoThe problem with this is that it prevents you from knowing when the microwave has finished.
- caf 4y agoThe cooling fan isn't supposed to be an audible "microwave is on" alert. That's not its design function. Perhaps the actual audible alert on yours should be louder.
- folmar 4y agoMy old microwave oven has a fan that is on only when the microwaves are on. If that was possible in 1985 it can be made the same way now.
- caf 4y agoNo doubt it was some combination of lower power, physically larger or simply more prone to failure. Do you suppose the designers go to the trouble of a cool-down timer just for the hell of it?
- folmar 4y agoI always use Reverse Hanlon's Razor, so I suppose they do it in bad faith. /s Actually I guess they both shave off weight/cost and design for built-in model first (that are naturally more heat-constrained) and make standalone variant as an afterthought.
- LorenPechtel 4y agoIt's more reliable if you connect the cooling fan to a thermostat rather than the power switch. Otherwise the hottest time is actually after you turn it off (as heat from the inside leaks to the outside but is no longer being cooled by the fan.)
