Vintage Air Compressor Cycles On And Off

The system works great im getting 50 degree air and the evap box isn't sealed yet, trouble is the compressor never. With the engine off and the ignition switch on acc, you could turn the blower on and off with no problem.


I'm charging a brand new system.

Vintage air compressor cycles on and off. The efficiency of the superflow design allows the use of a smaller area. Typically this means that you are low on freon. The problem is that the air compressor cycles on and off.

Clean or replace your air filters. The cycle switch did work on 2 parts, when no pressure on system it would not engage the compressor clutch and with only one can of 134 in the system it would cycle the clutch rapidly on and off, did ta=hat till i got the charge up to around 30. I evacuated the system (30 for two hours).

Your air compressor tank pressure has fallen to the normal cut in pressure setting, the pressure switch has tripped to on and power is flowing to the motor circuit, the motor starts, the pump starts pumping, then before the tank pressure reaches the normal cut out pressure, the compressor motor stops, then starts, then stops and so on. I added just a quarter can of refridgerant to it just in case it is low to see if it alleviated the situation. Short cycling, when the compressor constantly shuts on and off, is one of the most common air conditioning problems.

The engine was running and the a/c would not come on. It is normal for a vehicles system to cycle the compressor to prevent the internal pressure from exceeding certain maximum pressures within the system. Say your car takes 1.75 lbs.

Went back and talked with the seller. The compressor clutch kicks on and off randomly during the driving. That will usually tell you how much freon your system takes.

However i think i have gotten the holley solenoid to work though. I'm assuming you have a trinary, or binary switch and that the compressor cycles on and off? As long as it isn't rapidly cycling on and of it is working properly, however if it is rapidly.

Vintage air gen iv, sanden compressor, binary switch. This is an otherwise well running 1998 taurus. Your compressor is short cycling.

Compressor strongly cycles on and off and pressure fluctuates between 20 and 45, low side port tube is frosty but no freon will flow into system. Air conditioning trouble shooting faq's from vintage air the following guide will help the installer determine if a problem exists in the system that would cause a malfunction. The solenoid is much stronger at the very end of it's travel.

Also be a problem in the compressor's starting relay and/or overload protector or in the compressor itself. Drain down to full mark on sight gauge. There is no pattern to it.

Look under the hood for a yellow or blue sticker with a/c info on it. Its fairly quick and sporadic. When the clutch switch has failed, it will usually produce a few simple symptoms to look out for.

I had autozone test my alternator. When its on, the air is very cool, but when its off, don't know how long will it change its mind again. I pieced together an ac system, nothing on it is factory, i wired it with a relay, a gm style cycle switch mounted on the drier and a vintage air binary switch on the high side.

After exhaustive internet searches, i learned that vintage air is sensitive to voltage spikes and a spike will turn it off. I didnt want to add more in case i. Ac was always good, until recently.

This can be measured by multiplying (height x width x thickness). Cycling on and off is normal but yours is way way too fast. Over time, the contacts wear out and the switch must be replaced for the ac to function.

Sometimes an air compressor will turn on and off rapidly in an unending fashion, this is an occurrence known as short cycling. To make up for it he got one of those vintage air compressors for free (or what ever it will cost him to fix the gas tank). (this can be measured by multiplying the height times the width times the thickness.) this rule only applies to the tube and fin style;

The air pressure cycles a clutch mechanism. Poor idle performance could be a bad pump (not moving enough) or insuficient airflow (mechanicle fan at idle) across the evaporator. I think the motor is going out (stink of ozone bad when it runs).

Your system may have a rotary or slide type thermostat. If you are experiencing problems in the physical operation of the unit (blower speeds, door operation, etc.) we encourage you to refer to the wiring diagram located in. The efficiency of the superflow™ design allows the use of a smaller area.

Unusual cycles, such as when the compressor runs for a long time without stopping, shuts down briefly, then runs again for a long time, call for air conditioner repair. The a/c works well at first then quits cooling. I'm using a sanden 508 with my vintage air and the compressor cycles on & off frequently.

The good news is that it does not mean that your air compressor is broken or defective, however there is something going wrong that requires immediate attention so as not to permanently damage the air compressor on your. I would welcome any ideas and suggestions. The air flow from the vents is low and the compressor cycles infrequently.

I still need to run it more to make certain but so far, so good. The strange thing is the electric motor never turns off. As this switch continuously cycles on and off, the ac system operates its electrical contacts which subjects the switch to a high amount of wear.

From my prior question on 7/21/18 on my 2014 honda accord air compressor cycling on and off every 15 seconds and following the suggestion of topping off the refrigerant since it was still blowing pretty cold air during the 15 second cycling. The a/c never gets cold, so meti s even blow hot,and mpressor clutch infrequently cycles off.

A/c never gets cold and the ressor clutch cy es frequently. I'm at 35 and 165 in about 76 degree weather, i do notice that some times it will drop to 30 for a bit then come back up. Turn off vacuum pump, system holds vacuum without any needle movement at all for 2 hours.

Regardless if idling or driving, the a/c compressor clutch cycles on and off constantly. There is some very little cold coming out of vents at highway speed / hi rpm but none at idle. It could also be caused by the compressor shutting off and trying to come back on too soon afterward.

I added about 3/4 of a 16 oz container of r134a and it still cycles every 15 seconds on and off but really keeps the car frosty to the point the.
