Sorry been away from computer. The switch feels just right just not switching on slow speed fan. I am aware that it should only work when the unit is at a certain temperature and I can assure you it was very hot when I tried but nothing. Wondered if it could be the sensor?
Thank you Michael. I have just been on to the parts people and they are looking into which parts I will require.
Still waiting . They are arriving in the UK this coming week and will be with me the week after.
