The defrost water freezes and does not go down the drain. The drain is not clogged...could it be the defrost heater?

Answer Hello Joyce. No, the drain has to be clogged, or the unit is not level for the water not to drain. The heater is working if it is melting the ice and causing it to turn into water.
Is the heater made from glass?
