I haven't rated your response yet as I have only just found your full explanation in my e-mail. This is not you but a poor ask site as I only received part of your reply up to 'remove' then the answer ended! I did try to ask why this had happened but no one replied. As mentioned I appreciate this is nothing to do with you and now I have information I will follow this weekend and do the rating
I have got round to following your reply today and have removed the plastic cover, removed the smaller bulge plate but there is nothing behind it except the complete back cover that I have removed about 20 screws and although it is loose I still cant remove it. There is a cover near the bottom that I removed but that contained the heater element which I tested for continuity then put back. Have I missed something or does it necessitate removing the whole back panel?
The heater was just rows of coiled wire on heat proof card slots, do I have to take these out to access thermostats? Also I do have a test meter but how do I test them plz
At last, how stupid I feel ! I took the heater to pieces without realising it was only 2 screws to remove the unit. I have now done this and there is only 1 thermostat and it is an intregal part of the heater. There is no continuity across the terminals so I guess this is the fault?
Thanks for that, you were correct and I am happy with your diagnosis but it would help people like me if you assume we are clueless as I felt you were dealing with someone with a little knowledge. Things like roughly the amount of screws to remove and when I asked about removing the complete backing would have saved some time and e-mails to you. Having said that, it worked, I am happy so thank you
