Is your furnace blowing cold air? It could be an easy fix. In this episode of Repair and Replace, Vance show how to troubleshoot a furnace that is not blowing hot air. If the furnace is blowing cold, is running continuously or won't shut off, then check your thermostat settings. Alternatively, if the furnace blows cold air after ignition, then the limit switch might be faulty.
