Just installed a Dometic non-ducted, 13,500, low profile AC in MBR. It has froze up 3-4 times on me to the point I can barely here the fan blowing at all much less blowing anything into the cabin. The installer told me that the unit has to 'cycle' since it has no thermostat and to put the dial on half or three quaters so the compressor can cycle on/off and to put the fan motor always on high. Well last night left the dial on all the way and froze up again. I then turned the ac dial all the way off to shut the compressor down but let the fan still run on high thinking it would thaw quicker. Well it did. About 30-45 minutes later, water was dripping pretty fast onto my bed! I'm assuming I should have shut the unit completely off b/c I guess the fan thawed the coil and blew the condensation off the drip pan and down to my bedroom. Am I correct or is something wrong with the AC unit? Maybe to much factory charge causing it to freeze up or me not operating it like i should?
