I have three units on the boat here in Daytona Beach. Salon unit is a Cruiseair RX30C. Last week, while we were away and the units were on, the main breaker tripped, killing the water pump and the main unit. Found it pretty quick, reset breaker and everything worked OK. Today, I noticed the salon wasn't cooling very well, and when I touch the compressor unit coils, the top one was quite warm compared to the lower ones. Water flow is good, clean strainer. Would the coil temps indicate low freon, or something else?

If you are the one that has replaced triacs…I can say this….Remove the Yellow wire from the triac….If the thing it is powering shuts off….The Triac is good….The yellow wire is the signal wire that tells it to close and send power to whatever it's powering…

Sorry…I was reading PM's (which btw I wish folks would not do…send me email please)

The coil temps indicate a lot…Hot coils don't usually indicate low freon…If it was low they would not be hot…

What you are describing seems fairly normal….Hot coil on top & cooler coil below is good…

If the lower coil is hot too, then it may be time to flush….

OK, couldn't remember if hot on top cool on bottom was good or vice versa.

I'm running the main unit now (9:30 PM) set to 74 degrees, and the temp difference with an IR gun is 20 degrees (76 & 66).…That's 10 degrees, not 20…(we are looking for 15 to 18 degrees)

Cool air from vent is just that…cool, not cold...Was the actual cabin temp 76 ? And can the system suck hotter air from anywhere but the cabin ?

During the afternoon, it was lukewarm.

The coils now aren't the same as this afternoon. Now, neither is appreciably warmer than the other (top vs bottom)

The top of the compressor housing is quite warm. Not burning hot, but I wouldn't want to leave my hand on it

IR gun says top coil 108, bottom coil 93, compressor 140...This suggests you are low on R-22.  

Because it isn't doing much good, I turned the main unit off...Yes that's best till you get the charge checked because of that compressor temp…Adding R-22 will lower the compressor's temp, but raise the coil temps which is ok.

Company coming tomorrow though, and it'll be hot in here without the main unit.

Any clue what the problem could be? Other two units are running fine, and cooling nicely.

Yes I am on here all day…Well at least in the mornings, and then several times all afternoon & into the evening…Often from my phone…

I do like to teach & help, but it's also part of business & the hope that folks will buy from me for that help over other sites that might be slightly cheaper…

Old School Service & Support is the way I see it  

What is most frustrating is when someone comes here for free advise, then buys a cheaper unit, and comes back here for more free advise on that unit…I expect it to happen somewhat, but once identified, I'm usually not very helpful to the folks that do it…

Let us know how it works out…

Seen the filter thing many, many times: http://marine-ac.com/forum/mai…..e-checkup/

Please find that leak or you will burn up that compressor
