I HAVE MY COMPRESSOR MAX AKHL1230E AND IT NEVER TURNS OFF IT JUST KEEPS RUNNING

Hi
your pressure switch is bad. so it isnt cutting off the compressor. the part number is N003306SV and can be obtained from Dewalt on Servicenet.
Detail

Good luck and hope this helps

Typical scare thing friend.Don't be concerned with it.Keeps running just to keep the collant circulating.Most newer models do this per the manufacturer.

Hello
Check that the pressure switch is installed correctly,meaning there is a in and out.There should be.
If not try turning the pressure switch around or installing it reverse of what it is now.

Also there should be an adjusment on the switch to stop it from releasing at a certin pressure.I think 150psi is max.Set it below.

Hello: Max cooling is when the recirculate door opens. With the recirculate door open, 80% of the air flow comes from inside of the car and 20% is outside air. That makes the cooling more efficient. Normal a/c operation is 100% of airflow comes from the outside. These settings have nothing to do with compressor operation. Also Decreasing or increasing the amount of cooling has nothing to do with compressor operation, what that does is control the amount of air going from the evaporator core either through or past the heater core. The a/c compressor runs the same amount of time regardless of settings on the control panel. Also in cool weather the compressor runs in the defrost mode to keep the windows from fogging up. None of these settings affect performance, the only time performance is affected is wide open throttle (WOT) in that mode the engine computer shuts off the compressor to allow max power of the engine, ie: passing gear.. When A/C is selected the compressor is on, none of the settings will affect gas mileage, ie, low/high, max/normal 60 degree or 90 degree.

Pressure switch out of adjustment or no good. There are 2 adjustments on it, 1 for cut in and 1 cut out.

Ingersol Rand compressors are driven by a variety of motors and gas engines. They set the rpm of the pump based on the required cfm /psi output required by the customer and power source. Your compressor has aprox 12- 15 hp gas engine that develops full power at about 3600 rpm of the engine. The pump will most likely be turning about 1000 rpm. Easy to check, just mark both pulleys and count the number of turns of the engine pulley compared to the pump. Pump specifications can be found at www.grainger.com. You will find that most ingersol pumps turn from 650-1200 rpm for max output. You will max pump life if you are able to keep rpms low (600 - 1000 turns). The pump will not lubricate properly if you turn too fast. The compressor needs between 5 and 15 hp depending on the cut-out pressure. Full hp is required as the pump neers 175psi. Good luck with your project.

ONE OF THE MOST COMMON CAUSES FOR A SERVICE CALL IS EXACTLY WHAT YOU STATE, THE MAX SETTINGS ARE SET AND STILL ITS NOT GETTING COOLER, ESPECIALLY IN FRIDGE SECTION RIGHT?
IF YOU ARE MAKING ICE THATS DRY THE FREEZER IS OK,
THE PROBLEM 90% OF THE TIME IS THIS
AS THE FRIDGE SECTION IS RELIANT 100% UPON THE COLD AIR MIGRATING INTO THE FRIDGE COMPARTMENT VIA A LITTLE FLAPPER DOOR THAT OPENS OR CLOSES OR IN BETWEEN AS WELL , THUS ALLOWING MORE OR LESS AIR TO MIGRATE INTO THE REFRIGERATOR SIDE FROM THE FREEZER SIDE
THE STUPIDEST THING IS THE FRIDGE SAYS MAX COLD ON BOTH SETTINGS, ONE ACTUALLY CONTROLS THE COMPRESSOR AND DETERMINES HOW LONG THE COMPRESSOR WILL RUN IT USUALLY IS OFF AND 1-10 , THE ONE THAT TURNS OFF THE COMPRESSOR ISNT THE ONE THAT DETERMINES THE REFRIGERATORS TEMP! THE OTHER SETTING FOR COLDER FREEZER DOES!!!! TAKE THAT SETTING BACK OFF OF MAX FOR COLDER FREEZER AND THE LITTLE FLAPPER WILL OPEN ALL THE WAY , WHEN SET FOR MAX COLD THE FRIDGE SIDE STARVES!, ANY SETTING 1-10 SHOULD STILL KEEP THE FREEZER FREEZING AND MAKING ICE IS THE KEY! IF IT CAN THEN ITS NOT A REFRIGERATION PROBLEM , IT IS A CIRCULATION ISSUE

Unplug the compressor power chord. If you can turn the flywheel, then nothing is stuck. Plug in the power chord and try the compressor again. If it does not work, return the compressor for a replacement.

If you can't turn the flywheel, then something is stuck, return the compressor for a replacement.

If you can't return the compressor for a replacement, then try to take it apart to locate the problem and fix it.

It looks like there might be a knob which sets the max air pressure coming from the compressor. If there is one, this may have been turned down.

There are usually 3 pressure settings on an electric compressor. Compressor max, pressure switch cut on, and pressure switch cut off.

Inside the control unit is a spirally spring like diapragm, it holds a ball bearing that should shut off the compresor at max pressure. The ball bearing has probably fallen inside the tank. Now it won't shut off so it tries to keep runniong. The back pressure cause an overload on the compressor motor and so blows the breaker. You need a bigger ball bearing or a replacement diaphragm. However you cannot get parts as there is a safety recall see this site: http://www.cpsc.gov/cpscpub/prerel/prhtml02/02108.html
