Talking Lessons learned

Hey Newbies, here's one for your books. I got up this AM in Florida where it's been extremely hot and humid. Being new a full timing we decided to go with a single A/C unit to see how it holds up until we leave this Hot & Humid State. This morning I found that my A/C unit was cycling on and off every few minutes and the temp was slowly rising, so I panic. I cleaned the filter and tried it again. After it would shut off it would not come back on until it decoded to. I checked all the wires and voltage and all was fine. While standing at the thermostat, scrathing my bald head the A/C unit came on and went right back off. Since I didn't have a shirt on I felt the air which was hitting the thermostat directly since I had turned the vent yesterday to blow into the bathroom. When the door was closed the air hit the thermostat directly and the A/C unit has a five minute recycle time. I turned the vent away from the thermostat and problem solved and blood pressure is back to normal. Ducted air is great but you have to be smarter than it is. Have a great day, I will now.

Same thing happened to me. I had gone to bed early that night. I'm a light sleeper so everytime the AC cycles it can/does wake me up. This is why I usually switch the fan to ON instead of AUTO when I go to bed to lessen the cycling noise. This particular night I forgot to set the fan to on. I kept tossing and turning constanly being awakened by the cycling of the AC, every five minutes. I kept thinking, why is it doing that? I never did wake up enough to go check things out.

I finally got up in the morning and found that someone had turned one of the vents so that it was blowing directly on the thermostat.

I was so glad that it was something simple.

Yeh, I'm like you. I turn the fan on at night too just to keep the air moving so I didn't notice the cycling until I got up this morning and turned it back to auto. Boy what a big relief after I figured it out.

Thanks for the posts, guys! Something as simple as this is just the kind of thing that many people might have overlooked. It makes so much sense when you think about it, and it may have saved me from a similar situation down the road.

Thanks again!

Ice

I don't know about RV A/C but I do know that when a home A/C unit starts building up ice it is usally caused from low freon in the condenser.

Running an RV A/C with the fan on low can cause it to ice up also. Usually in high humidity.
