Furance hot an not blowing off heat
I have a electric furance it is a coleman evcon, model number 7681-8191/A .standard blend air ll. I can smell it getting hot, yet the blower will not kick on. So I have to go and switch it from auto to on an make the blow work. It does not do the all the time just every now an then(mostly at night). I had a man come last time it done this but he said it has to be doing that at the time for him to figure out what was wrong. Took my money for service call an left. I can not afford to have people in that is not going to fix the problem. I could an would love so help.
