The unit is a Bosch HBC 84E 653B approx 2.5 years old. Although the oven function is working fine, the microwave, regardless of the time set + or -, the duration symbol comes and the microwave switches itself off after a number of seconds. We cannot turn off the duration icon to rectify this.
Its difficult to tell in such a short time, but it runs but doesn't seem to be heating.
No; just set the timer for 1 minute; same sounds a usual, but it switches off after @ 45 seconds, with no apparent heating.
Thanks Ian, the problem is the main control board. unfortunately they don't sell parts for that only the complete board. I can help you replace this, its really easy and requires only a few hand tools. But there are some concerns you need to be aware of. Microwave ovens can contain lethal voltages even when power is removed!!! But you wouldn't be working anywhere near that spot. I can help you get the part as well, or if you decide, you can have an appliance tech do this repair for you. It will still be quicker and cheaper if you have the new board before calling them. I will stick with you until this is fixed but since this may take some time, if you will rate my service in a positive fashion thus far before you close this page, the system will allow me to schedule free follow ups with you and also ensure your question will NOT close or time out;-) You will then be able to contact me at anytime at no additional cost until we have this fixed for you. Thank you Ian and have a great Sunday! Tech Michael
you offered to advise me on the replacing of the board for my Bosch combo oven /microwave ( yesterday the 18th). Could you give me details of the specifications and prices so that I can buy one please.
with thanks, Ian
Hi Michael; if its a simple fix then I'd be grateful for the information as to where to get the board, how much etc. Thanks, Ian Macrae
Thanks Michael; what is the exact description of the board when ordering ( I already have the Er numbers etc from the plate ).
OK Michael, thanks for that. I will call them and check prices, which will decide whether I go ahead. To be honest I'm not very impressed with the various Bosch products I've had recently, especially this one.....tries to do two functions, neither of them very well; too complicated system and incomprehensible instruction manual. I'll let you know the outcome. Ian
No more info needed thanks; I've decided not to change the board, just use the 'combi' as a 2nd oven with a separate microwave. Thanks for your help anyway, Ian Macrae.
