Hello, is the condensate pump sump dry or is it completely full of water, if its completely full it may be the type with a float switch that shuts off the AC when its full

Look into that, we can go from there

Condensate pump is completely dry. I forgot to mention that Honeywell emailed me earlier in the morning and told me the furnace was not communicating with the thermostat, which shows nothing, just a black screen. When we found that the noise we heard was the condensate pump continuously running , we pulled the plug on it. The furnace will not come on.

Thanks, ***** ***** of course is with the thermostat, OR the printed circuit board it is connected to inside the furnace....not at all an easy diagnosis.

.

A technician would simply attach a known good thermostat, and if that allowed the system to work would replace your thermostat.. if that failed he would replace the printed circuit board inside the furnace/air handler.

(after checking to make sure all of the wire connections were correct and that the 3 amp fuse in the printed circuit was not blown etc.)

.

Its time to locate the 'Finish and Rate your expert' link to close the question.... unless you would like me to coach you on a deeper diagnosis using a multi meter, that will take a few hours, there is no additional charge...

In that case you would also need to rate my work so far positively so that I do not loose my shirt going the extra mile for you on this.
