Thank you, Doug. I was hoping you'd show up. I've got the older 5 button CCC. I finally did get the heat pump to go into defrost yesterday when it was 33 degrees out. I did notice that it appears as though the word "defrost" only appears on the CCC when the unit is actually defrosting, that is, when the fan is off and the freon reversed. I thought it would stay on from 30 to 42 degrees to let you know it was in the defrost state. If that is what it's supposed to do, that is, stay on the entire time that its between 30 and 42 (approximately), then the sensor is definitely bad. I'm pretty well convinced that is what is wrong. So I'll order one. They list two, one that is 24 inches and the other 48 inches, but from the pictures it looks like only the 48 inch one has the red plug that's correct for my control box. I can't tell for sure from the picture about the 24' one.
