I have a Nordyne Intertherm High Eff Furnace about 4 months old. The gas valve began cycleing on and off during operation and was cutting out prior to the warming cycle being completed. I noticed excessive water in the condensation drain line and with an outdoor temp of -18 degrees I thought maybe the line had froze up under the house and drained the line manually. Would a frozen condensation drain backing up to the Inducer Assy cause the gas valve to malfunction?
