Now Thursday and Friday I will say it ran just about 24/7 except for night when I have it go to 66, at which time it will cycle. Ours had an issue since we bought the house that at temps below freezing at random the outside unit would be shut down in lockout mode for low pressure, the unit would be frosted over, and the breaker for the aux heat would be tripped. It was completely at random and could go a long time then suddenly do it. Winter would then be over and I would forget about it until it happened again the next winter. When it happened I would reset the tripped breaker, short the defrost pins and it would go into defrost mode and be fine. All I have read indicate that the defrost board is fine if jumping the pins puts it into defrost.
I also had read about testing the coil temp sensor and/or make sure it was attached. This one is hard wired to the board so not really a way to test it. The sensor was properly attached to the coil as well. Finally I decided to get someone to look at it but thought before I do, I’m just going to order a new board for it. I did that which comes with the hard wired sensor of course. I also went ahead and replaced the breaker. Never had a problem since. I suspect perhaps it was the coil sensor not seeing it needed to defrost, when the heat strips kicked on it would trip the breaker.
