Air Conditioning - Rheem condenser shuts off, high presure reset

I have a Rheem RAND condenser, it will switch off after 30mintues - 2 hours and i will have to hit the high pressure reset button to get it going again. The system is only about 2 years old.

Even at the sharp angle of the second pic, I can tell that the outdoor coil is filthy and needs a good cleaning.

That coil should be cleaned at the begining of each cooling season.

i cleaned out the outside coils with a pressure washer, but its still switching off. Ive also noticed that the compressor gets "boiling" hot, could there be too much refrigerant in the system?

Update: I just talked to my AC/heating guy and he says the lines that go from my condenser to blower have too much of a vertical slope so it makes the compressor work hard and overheats it, which is true this unit cools my 2nd floor and almost go directly up my house, to the attic where the blower is located.

Update2: Problem solved, line was clogged by peice of solder

Pressure wasing coils doesn't do a good job of cleaning and can damage the coil.

Find an A/C supply house in your are and buy a "Coil Gun" made by NuCalgon. Also buy a gallon of foam brite condenser coil cleaner. Disregaurd the mixing directions of the foam brite and follow the coil gun directions.

You are supposed to clean the coil from the inside out but the compressor does get in the way. So do it both ways.

Wet the coil first as pflor said. Wash with coil gun on low (E) setting and watch the dirt foam out. Rinse and reaply. Rince and try it our. You will see a difference.

Add this to your spring outdoor chores.

You probably packed the dirt in tighter with the pressure washer. The Cleaning chemical is the way to go. I have never used a coil gun, I just use a simple garden sprayer to mix the chemical in and spray it onto the coil and then a water hose for rinsing. I will have to check into that coil gun thing and may GIT ME ONE if it is not real expensive, how much cash did you invest thar dad?

It's about 30 to 40 bucks, least when I bought mine.

Prove it to yourself same as I did to Techs here after moving here.

I was out on a Pm with another guy. You know, clean condensors, change filters & belts, check all elec connections, log the unit etc..

So this guy, Ronnie, pulls his pump up to the roof, mixes, rinses the coil (inside out to his credit) sprays both sides, rinces, and repeats. Ronnie is finished with the coil and remarks it's time for the next one.

I asked "You think that coil is clean?", "Yes, thats how we do it.". Watch this, I went down and got my gun.

I must admit I did have an advantage as the coil (and dirt) was very wet at this point. But you should have seen Ronnie's face when he saw all this dirt and bugs and junk foaming out of the coil.

Did it twice, second time mostly white foam. Rinsed and told Ronnie, that is a clean coil.

Have a few more stories (perhaps better) but you get the idea. I use mostly 3 to 1 rather than 10 to 1 (Foam Brite bottle directions) becuase you will use more product at 3 to 1 than your used to. Also the first pass will really loosen stuff for the second or third.

May have to raise the rate of the cleaning, but when you are done you will know It Is Clean.

Not sure who is there and listening, but I'm a single mom needing to know where is the reset button located on the rheem. Last year I had the same problem I'm having now, not blowing cool air, and it cost me $75 for someone to come out and push a reset button. Help please!!!!!

Hello
Can you tell me where the reset button is located on the rheem. Cost me $75 last year for a repair person to hit that button. Help!!!!!!

Look at the side of the outdoor unit where the pipes enter. TH side with the metal cover. On the bottom there is a small red button.

There isn't a room full of people here just waiting for the next post. Just waiting to give a suggestion.

If you wanted faster answers you might have tried to open a new thread all alone, so people would know it was new and not an add on to something that is pretty much over..

Good Point dad, she may just be a bit grumpy from the heat though, she did wait 4 minutes between posts
