heat/ac help

[workingonadream]

I was running my heat Thursday nite and after several hours caught a high head pressure code. the next morning I checked the discharge side and all was fine. turned the unit back on and it shut off in 5 to 10 seconds, but now im not even getting a code it just starts and shuts down immediately. I don't think it could heat up and build pressure that fast and shut down. its a cruisairs system any thoughts are appreciated thanks

What are the pressures?

 

[workingonadream]

I don't know the pressures didn't have gauges with me to check, the problem is definitely on the a/c- heat side of the system and not the d/c side. even if I have a blockage on that side of some sort I would think the system would stay on for more than 5-10 seconds. I rang out the high pressure switch on the system side and it seems to be fine. would a blockage or low refrigerant cause it to shut down that fast. thanks

Too many variables. Too little information. What model cruaisir and what control system. Does it work in cool? Could a valve be stuck? ....

no doesn't work in cool either, and I don't have the model number with me. I was just wondering in general terms what peoples thoughts were on the unit shutting down so fast. i am hoping it is something on the unit and not the unit itself. just want to know if anyone has had a similar experience and what their problem(s) were . thanks
