Hi Lisa, could be the thermostat has tripped or is damaged or your heating element has gone. Do you know someone who could check these for you? Thermostats can sometimes be reset and if it is the heating element or a new thermostat that is required,after checking, then there's plenty of places on this site that people have recommended for spare parts. Alternatively if you know someone that is an electrician or knows an electrician they will be able to do this job for you at a reasonable price. Remember that before you open up any appliance to disconnect if from the power supply.
