I have an electric Kennmore Dryer DWSR-ELE-2406028-CV54 that seems to run OK, but the heat is not coming on. There are no blockages on the vent and the filter is clean. What can you suggest?

Before you do anything on the machine you should first verify you have 220 vac. Unplug the machine and test you outlet with a meter that can handle 220 vac, no lottle pens please.
