AC Issue I'm not sure?

Last night was hot this morning was cool. My AC was short cycling it would come on run for 25-30 seconds and cut off it did that untill I got up and lower the set point. Has anyone else expirenced this?
  • I had a similar experience when my fan setting was on auto. Instead, changed it to Hi setting and worked fine. Set it on low fan and worked fine. Each time I set it on auto it would cycle back and forth between high and low fan. When that happens the compressor will stay on but the fan will cycle back and forth similar to a short cycle symptom. You might see if yours is doing the same. I've found it's a common problem with Dometic units.
  • I think it was set to cool. Back home now will try it tomarrow. Thanks for the tip!
  • Do you have it set for "automatic" at a set temp? The system will run until it hits the set temp and then shut off, and restart when temp rises above that number.
