Hi I have a Clare Hecla furnace and I have a problem where I've set the controls at OFF-110F and ON-150F with the limit at 170F. My furnace blower runs continuously 38mins to 24 minutes at a time and shuts down for a 2.5 minutes average. When the heater is on the blower continuous running and never stops for the heat. My heater runs on for 2.5 minutes and then shuts off for 12 minutes and turns back on. I'm trying to get the blower and the heater to run synchronized but the blower almost always runs continuosly. It is late October and its getting to -5C at night, so if anyone can give me some advice about what to do it would be much appretiated.
