Superheat Problem I had an aircondition installed yesterday by a technician and today I did some measurements and found something that I do not understand. The system is using R407C refrigerant and is 18000 BTU. I found the following: Suction Pressure (70 psig) Suction Line Temperature (93 degrees Fahrenheit) Evaporator Temperature (43 degrees Fahrenheit) Outdoor Temperature (100 degrees Fahrenheit) Does the above mean that i have Superheat 50 degrees? Is this normal?


Superheat is the dif. between suction temp on the gauge and temp on the suction line. Make sure you are measuring the right line/ Normal superheat is between 10 to 14 degrees depending on line length. Russ ... Air Conditioners

I have a Carrier split unit model 38AN009100 that I am using to refrigerate my wine cellar.I know that this unit is not made for this purpose. Is it possible to convert it so I can control my cellar at around 12 degrees C? I was wondering if I could put a wall thermostat in the cellar instead of the actual thermistor controlling the temperature. Thank you for your prompt reply


Well most unite will but out 54 degrees but as far room temp reaching that is highly unlikely. the unite would probably turn into a big hunk of ice and stop! this is more of Refrigeration unite which operate at lower temp. you can buy small ones fair ... Air Conditioners

Just bought a used 1987 Real-Lite truck camper. The roof air unit is Dometic as well as the LP/AC refrigerator. When turned to "cool" the air conditioner really draws down, dims the lights, and eventually blows the home AC breakers. It works fine on blower fan only but as soon as I engage the "cool" settings, big brown out. The fridge doesn't work at all. I'm in the Nashville area. Suggestions


To start with, if it's plugged in to a 15 amp breaker, and extension cord, the compressor starting up may just be enough to trip the breaker. It will draw close to 15 amps on start-up of compressor, and if there is a light extension cord used to plug ... Dometic Rooftop RV Air Conditioner
