That's good that you replaced your compressor and dryer on the 2001 Durango and evacuated and vacuumed the system for 1 hour.

Not everyone can do that.

Now, the problem is the safety lock out.

In my experience with Cadillac automobiles from the 1990s and 2000 and beyond, the safety lockout is erased when disconnecting the battery for 3 to 5 minutes, and reconnecting.

This erases the lockout feature in these cars. I suspect that you have a similar problem on your Dodge.

Also, check that all of the connections are ok at the harness to sensor connectors for the high pressure and low pressure sides.

Sometimes this can be the problem.

The fuses should also be checked to make sure none blew out under the hood:

SOURCE: Last year I got my ac refilled with r 134 and it all leaked out in a day. My mechanic told me that I needed a new condenser. I changed the condenser and the lines myself. Now I don't know if I should

The system has to be evacuated and recharged you didn't say what type of car but this has to be done on all 134 leaks faster then r 12 as a thinner gas

I own a Fogel Fridge Model # VR-17-RE-PR Recently

It is important to know if the compressor itself is running. If there is a loose connection to the compressor via the start/over load relay (normally attaches directly onto the compressor), or if the start/over load otself is bad the compressor will not run. Best way to tell is via gauges but I doubt your frig has ports. Check to see if your compressor is really hot. Could be bad start/over load relay or bad compressor. Try unplugging your frig for say 30 min then, with your hand on top of a cool compressor, plug the frig back in and see if compressor smoothly vibrates for at least 5 min without becoming very hot or shutting off even though fan continues to run. The fact your fan is running TYPICALLY means the thermostat is calling for lower temps and the fan/compressor kick in together.

Refrigeration and Absolute Vacuum

I have noticed some good advice here when it comes to pulling a vacuum and recharging a refrigerator. I also have seen some not so good response to answers when it comes to someone that is new to pulling a complete vacuum. *Refrigerators and absolute Vacuum are about the most difficult combinations to obtain. First mankind has never achieved absolute vacuum and the closest we will come in our life time to complete or absolute vacuum is in outer space. When repair is done to a sealed system there are a few things to remember. 1 Once a sealed system is opened never leave it unsealed to the outside environment. Most new refrigerators have ester oil as a lubricant and ester oil will draw moisture from the air and hold it in the oil resulting in the oil carrying moisture particles up the capillary tube and creating a blockage that appears as if the suction side is pulling a deep vacuum. 2 Always replace filter drier with a new filter drier and arrow pointed into the correct direction. 3Always find and fix a leak in a sealed system before recharging. * Some leaks are in the Yoder Condenser Loop and the only way to fix is to bypass. This will sometimes show up as sweating around the door frame but much better to deal with than complete refrigerator replacement. 4Pull a vacuum as long as it takes to boil off any moister that may be trapped in the sealed system. If system has no leaks and you use a heavy duty vacuum pump this is about a hour. 5Always test gauges for leaking seals in gauges before spending so much time pulling any vacuum. *Bad gauge seals will result in moisture or poor vacuum results. 6Always charge refrigerators by weight. *Refrigerators use very little Freon. 6-8 ounces, over or under charging will result in poor cooling results all the time. 7Never try to solder steel to copper piping with just silver solder. * Always use eutectic solder for soldering copper to steel. * In this case eutectic solder is defined as Flux-Coated Silver Brazing Alloy. For example Safety-Silver 45 by Harris. 8Always use the correct oil for the correct refrigerant. * Too much, too little or wrong lubricant will damage the system. If you have questions please let me know, Thanks, Sea Breeze Here is more....... As we talked earlier I did some research on Fijitsu Split systems and as always with these units they is very little in instructions or model/size category to give good solid answers to all the possible problems you may be having. I do know with my experience that the R410A are critical during installation that they havea very good and long vacuum during pre-charging the lines during installation. One little bit of outside air in the lines will cause extreme head pressures that will also simulate some of the symptoms you described today. R410a runs at 60% higher pressure that the older R22 units did and purge and clean silver solder of fittings is critical to the unit's performance. Even a crimp in a discharge line makes for problems during installation. here is a link=> Brochure here=> If you need more answers feel free to contact me here or through my profile and again Thanks for using Fixya, Sea Breeze

I have a Mini Split Airconditioning Unit and I found a leak at the flaring where my Suction Line comes the Condenser. How can I fix the flare. Must I isolate freon first somewhere in the system so as to be...

There is seldom a means by which the refrigerant can be isolated in this type of system. Moveover, since the system has had a leak, the refrigerant in the system is no longer usable. It is made of HFC-125, HFC-32 and HFC-134a in specific proportions. When a leak occurs, these components will leak at separate rates and the remaining refrigerant (if any is left) is no longer capable of doing the work of a virgin refrigerant.

Refrigeration flare fittings are 45° and are made with special tools. While there are 'washers' that can be inserted into the fitting when it's exposed, they are not that effective all the time. Remember that the pressure at the condenser part of the system can well exceed 300 psig.

The refrigerant, Genetron 407C, is the replacement for HFC-22. It has no 'replacement' per se.

It's my opinion that this is an issue for a reputable HVAC technician, and not a homeowner. To do the job properly, you would need a new filter/drier, flaring tool and torch if the line is not long enough for it to be re-flared and reconnected, vacuum pump and virgin refrigerant. I would bet that the location of the leak is such that the system is all but flat at this time, and you need a precisely measured amount of refrigerant to re-charge the system.

If you've not yet done so, TURN THE SYSTEM OFF to protect the compressor from damage.

1997 Mustang GT,hooked up R-134 to low fitting can still full not charginng,compresor working,what do i need to check next.

The R134 sorry to say, should not be sold to the public.
They required a licence to buy R12 ,R22 Etc but not 134

What you do or did was let air into the system,when you hooked up the short hose. There was air in it. Now it is in the system

Also the only way to charge any A/C system,not just vehicles,is to recover all refrigerent,repair leaks,pull a vacuum,check to see if it holds,them charge to thje required oz or weight. You have know way of knowing what was in the system when you started. If you had to add you have a leak. Now you put holes in the atmosphere and help out global warming.

Not trying to be cute here,just referencing how refrigerant physics works.

You can not push in what dupont calls freon,even under pressure, unless you heat it,so it changes state at some point. Has to go in under a vacuum.

You need to pull a vacuum now, to remove the air.
While you can compress air,you CAN NOT compress the water vapor in it. In fact you can damage you compressor.

Sandwich prep refrigerator too warm.

It sounds as though you have a clogged capillary tube, cannot be sure without suction and liquid line pressures and temps but if you can, ask the tech if the suction pressure seemed to be low, if so, replace the capillary tube with the proper length and diameter tube, replace the liquid line dryer and pull a GOOD vacuum on the system and recharge it, refering to the rating plate for the proper amount and type of refrigerant.

things you need(to do it properly) vacuum pump,r134a gauges and leak detection of some sort first locate lowside port connect blue connector from gauge to it (lowside is the skinny hose)connect vacuum pump to yellow line open valve on blue guage manifold.
pull a vacuum to less than 30" hg for thirty minutes.close bluevalve on manifold watch needle make sure pressure doen't rise if no change in pressure after 15 minutes no leak.if pressure does rise then you have a leak and need to find it.(cheap/messy way use get a can of 134 with dye in it fill system and let it run look for dye on system usually on pump around back of clutch,unless you replaced a compnent recently then check all fittings and seals.)
you will add r134a through the yellow hose.

Need to know normal pressure for 134-a to recharge my refrigerator

Depending upon the way you charge it you could introduce air into the system. The lines need to be bleed before charging to make sure the refrigerant is in the charge lines and not air. Most folks that do not do this for a living make that mistake.

With air in a 134 system problems will abound. The only way to really charge a system is to use a vacuum pump to pull it down then charge to the correct lever in ounces as provided on the label of the refrigerant u purchase

Replace compressor

This type of work is normally performed by a certified technician. System refrigerant must be recovered prior to working on the system. After refrigerant is recovered from the system the lines can be removed from the compressor stub tubes by heating up to the flow point of the solder used. Number 15 silver solder has a flow point of 1385°F. Re-brazing the lines to the replacement compressor is best done after cleaning the line and using a small amount of flux. I use #45 silver solder to connect the lines to the compressors on a replacement. Flow point of #45 is 1185°F. The system filter/dryer should be replaced. After all connections are made a vacuum must be drawn on the system to remove air and none condensible gases and moisture. Refrigerant charge is critical on these system and should be weight in according the the amount stated on the name plate.
