Have a LG Electric Stove Range and one of the front cook tops was not heating up every time correctly. Contacted Jim & Daves and they diagnosed problem as the relay board needed replacing. The part had to be ordered and when it was in, the technician arrived at the appointed time and quickly replaced the relay board within about 15-20 minutes. I was very pleased with the technician and the company's professionalism. I would highly recommend them.
