You are low on Refrigerant. you are cycling on the low pressure control.

no freon, no cold air.

my compressor keeps tuning on and off(on then one sec. latter off then two sec latter on for one sec. then off and so on) I do have good Psi. but it just blows warm air? Can someone help me?

[2hatelibs]

did you ever work for the usps, how slow can you talk???

[Mooseguy15]

@TheTarrMan how does it turn on and off like that usally if it turns off the compressor is under to much preassure meaning it;s not equalized so it doesnt have th power to overcome the head preassure so they shut off. so i don't see how yours starts and restarts cause i usally gotta wait min 30secs. max 5 mins

Here is a good website:

Manifolds for pressure testing? Perfect way to loose an eye. Seen it happen.

clloyd234 how are you hope you are doing good i have a question i asked already this question but i want ask it again hoppfuly you can answer it the yellow hose of the gauges is connected to nitrogen tank and blue hose of the manifold connected to robinaire machine to vacuum it is this the way thanks again great video

[ilookedupandsaw]

@theASEtech Blue hose is connected to the low side or suction line

[theASEtech]

this is the first time i see this video and is is very nice the way you are showing how is done the charging and evacuating in the system i would like ask something that i dont see when you are pressure testing i see the yellow hose connected on the nitrogen but the blue hose where is connected on what part of the machine i appreciate the answer and nice meeting you at the video thanks

Great video thanks mate. A note though it's good practice to never open the bottle with the regulator open to working pressure side. As I'm sure you may rememebr from school there is a Bourdon tube inside the gauges, they have been proven to become less accurate over time from doing this, and have also been known to fail due to this. Best to Open the bottle, then Open the working pressure, as working pressure side is delicate inside due to the Bourdon tube. Cheers mate. IC.

@JISINSANE3 is correct.. Amonia was replaced by Freon because of a several reported deaths from the use of methyl chloride as a refrigerant...Amonia was tarred along with Methyl Cloride and Dupont / GM developed FREON...IMO and others ive talked to, Freon was only replaced because there was no longer big money to made in it..  R134a allowed the chemical companies and service industry to charge higher prices on supplying and servicing an inferior refrigerant prone to leaks, compressor failure
