ac froze up when fan on low speed.
Exactly twice my a/c has frozen up.Once last year and just this weekend. Both times it was very hot and humid and the unit ran all day trying to keep up and at some point the fan speed was set to low...

When the defrost cycle activates on my Dometic Penguin on low fan speed, it interrupts the compressor and speeds up fan temporarily. While it is better than the unit freezing up, to me it is less desirable than not having it happen at all. I have never entered the defrost cycle on medium or high fan speed.
