Hi Vishnudas, the reason your m/wave is not heating can be down to 2 things, but the most likely with sanyo is that the magnetron (the thing that makes the microwaves) has gone, unless this was an expensive model it is probably not much more to purchase another new unit. For any further assistance parts etc contact me via microwave-repairs.co.uk. The rules of this site prohibit me from giving an email address in a reply.
kindest regards
