My tumble dryer is only blowing cold air and does not dry the clothes. I have thoroughly hoovered all parts of the dryer to ensure that the filter and unit is fluff free, but this has made no difference. I am guessing that the thermostat needs replacing, and believe that this is the right part for my Candy CDC266, but cannot seem to work out how to get to it to change it! Have you got any advice that would help me to track and replace the part please? Thank you.
