Heater on all the time

[Ian5700]

What would cause the heater to be on all the time, regardless of the temperature settings? I know that this could probably be a few different things, when it happened the heater was on and the temperature guage is operating as normal. You can get cold air out of the system with it turned to max ac, but not ac. It produces quite warm air, but not extremely hot air. I assume that the fault is in the control panel and it is just stuck on in the hot temperature range?

Oddly enough, the problem fixed itself today, and the system is working normally now.
