Thank you gentlemen for the prompt response and valued advice. I went to my father's house to remove the motor and blower unit this morning. When I arrived I turned the furnace on and it fired up immediately for a few minutes as usual. Then suddenly the motor kicked in and began working. This threw me off and I was pleasantly surprised but also concerned that if the problem re-occurred that I would have no idea as to the actual problem. The motor sounded fine and there was no strange sounds coming from it or the blower unit. My father who is a month away from being 90 was relieved and we went upstairs to talk about old war stories over a cup of coffee. Long story short, the furnace went off after reaching the proper temperature and when it came time to kick back on, the burners ignited but no motor or blower action. So, it looks like I will need to call someone in to determine what the problem is. I checked the wiring for corrosion and it all looks good. I lubed the motor shaft and also the blower motor shaft and bearings and the unit motor comes on intermittently. Anyway, your help was appreciated. Will give a tech a call tomorrow to see what the problem may be. thanks Alan
