Hey eveyone, we slept really well last night until we woke up to a non-working air conditioner. ( We are in Texas, so this is urgent!) We can see ice on the compressor and chunks of ice seem to be falling off. Can anyone tell me why it iced up to begin with and how to prevent it from happening again? It seems to be cooling down now.
Welcome to the forum. It would help if you said what type RV and AC unit you are using. Is it a rooftop unit, a portable, or some other type? I'm sure you will receive a bunch of responses from those members who know a lot more about this problem you are having once they have a few added bits of info, etc. Hope your problem will be resolved shortly...........

i could be wrong on this, but i think the unit needs plenty of airflow to help defrost the coils. check your filter to make sure its clean to allow air to flow.
Yep, and if you have a fan speed selector switch, keep it set on high. Many, but not all, RV air conditioners have a temperature sensor inserted in the coils that shut off the compressor when icing conditions are sensed. Occasionally, the sensor vibrates out of place and no longer tells the compressor to shut down.
Yep, when we had a travel trailer, if we didn't keep the fan on high it would ice up. Plus i removed the cover from inside the trailer, and used that aluminum tape to seal off the two air compartments inside that chamber. It was poorly made or at least poorly installed allowing warm air to mix with the cold air. There are a few You Tube videos showing what I did and it helped get us colder air when it was hot outside. Very easy to do.
Icing on your AC compressor can result from low refrigerant levels, restricted airflow (due to clogged filters), or thermostat settings set too low. To prevent this, change air filters regularly, schedule maintenance, ensure proper insulation, and set your thermostat at a reasonable temperature for Texas weather. If issues persist, consult a professional HVAC technician for a thorough diagnosis and solution.
