Greetings,
You guys have always given me very good information on this site and have helped me diagnose and replace a bad sequencer and fan motor in this unit before and I can not tell you how much I have appreciated that help.
With the mild winter we have been having down here in Chattanooga I have not been having to use my central heat very much. I have two oil filled radiant type heaters that have done a good job most of the winter for me and seem to be more economical that the central heater. I set that to 68 so it only cuts in when the little heaters can't handle the load.
That being said I have noticed on a few recent cold nights that the central heat cuts on but only seems to blow cold air and never seems to bring the temperature up much if at all. It looks like it just runs continuously until the sun comes up and it warms up enough outside for my little heaters to finally bring the temperature back up.
Could I have a bad heating element or some bad relay/sequencers, etc.? Could you offer me some advice on how to determine the problem? I work on X-Ray equipment for a living so I am not squeamish about poking around inside live equipment with a voltmeter.
