Since sending the question I've noticed that the display shows the "Inside" temperature but does not show a "Set To" temperature on the Cool setting, only on the Heat setting. So display simply reads "Inside 88". Its a Honeywell TH3210D1004.
OK. No click at the thermostat (the display does light up), and the outside unit is not running. Note the thermostat is on the "Auto" setting. In the "On" setting it turns on the blower but again the outside unit does not come on.
Just pop it off the base on the wall? No problem. What do you need me to look at?
Yes, outdoor unit kicked right on.
Wow. Even though the house was just built 11 months ago and it's all brand new? Would a defective unit explain why I can change the temperature in the "Heat" setting but not even get a "Set To" option in the "Cool" setting?
Well I'll give it a shot. Hope it's a Lowes unit given that it's a Saturday night. If she keeps giving me trouble I'll give you a shout. Thanks for the help!
