I have a Holiday Electric Range (who really makes this brand?) and the stove top is no longer working. The Power comes on but the coils do not heat up, however the Oven portion does heat up. This is an old range and I have to movea few things before I can get to the model number etc. Is there any troubleshooting advice someone can share with me or point me in the right direction where I can start first. Your help is appreciated. thanks
