Hi, welcome to Just answer
Please tell me its complete model number and/or how old is it ?
Also please elaborate not working ... is it completely dead or it works and then stops so that I can tell you what is causing this ?
OK, do you hear any unusual sounds from the microwave when its trying to start ?
ok, the problem seems to be with the power board that is bad and will need replacement
a new one will cost you around £180 including labor, looking at the age of the unit its better to buy a new one...you can also get a repair quote from www.repaircare.co.uk
