Good morning Tricia,
Here is a link to the best place for that main board for your HOB.
Its best to simply call these guys as they do not list all parts on their website that they carry;-)
Please cal espares to order the main control board: Call 0844 9777 888
Once you have the board I will instruct you on how to replace this part;-)
In any case, I will stick with you until this is complete.
Please rate my service kindly.
Also it is the only way I am credited for my time and expertise with you.
Once you rate, I will be notified and will add your question to my priority list so you can reach me anytime until this problem is solved.
Then you can reach me by simply replying to this message anytime.
Thank you and have a wonderful weekend Tricia!
