Just before Christmas the thermostat on our Canon failed due to
excessive temperatures and blew the door out. This was repaired at the
time and since then. the oven has worked fine.

Yesterday however, when we were cooking tea, the whole electricity for
the house went off and we had to flip the switch for the main
electricity to the house. From this point onwards, the over will not
heat up, no matter what the temperature setting is. We have contacted
the company who did the work before Christmas and they are saying the
work was only covered for 3 months.

Does anyone have any suggestions on what we can do next, its looking
like a new oven but as this one is only just over 2 years old I'm not
really that keen on forking out for a new one
