What is an AC binary switch?
From TBI Products. This Binary switch provides 2 essential air conditioning functions. It Protects the system (by disengaging the compressor clutch) from excessive high pressures or low system pressures. Don't forget to install a safety switch. via
How does a binary pressure switch work? (video)
What is the difference between a binary switch and a trinary switch?
A “Binary Switch” incorporates both of these protections into one switch. A “Trinary Switch” incorporates both high and low pressure cutoffs, plus adds an “electric fan engagement signal” (at 254 PSI) feature to help bring internal temperatures down. via
What does an AC low pressure switch do?
Your car's air conditioning system has two switches that protect the compressor and the refrigeration circuit. The low pressure switch turns the system off when the pressure is too low to prevent damage to the compressor. Like all parts of your vehicle it has a limited lifespan. via
How do you wire an AC to an electric fan? (video)
How much freon does a vintage air system hold?
Vintage Air's standard charge recommendation is 1.8 lbs (28 oz) of 134A refrigerant. This charge will be correct for most standard installations (dash-mounted systems), but some additional refrigerant will be required for a trunk-mounted system with a liquid line of more than 12 ft. via
How do I test my AC pressure switch? (video)
What's the purpose of a pressure switch?
Pressure switches are used to monitor pressure in pneumatic systems by providing an output when a set pressure is reached, as well as improving operation and safety. via
Where is the AC low pressure switch located?
The low side service valve is located in the line that runs from the compressor through the evaporator (firewall) and up to the condensor on the low pressure (suction) side of the system. via
What is a C trinary switch?
Before we get too far, it is important to understand what a trinary switch does. It is a safety switch for air-conditioning systems. It is a three-function switch (tri-nary). It automatically shuts off the power to the air-conditioning clutch if the refrigerant pressure gets too high or too low. via
What is a Trinity switch?
The Trinary switch is a 3 function switch. Protects the system from excessive high or low system pressures plus it will automatically operate electric radiator or condenser fans as needed for maximum system performance. via
How do I know if my AC pressure switch is bad?
If the AC is cutting on and off rapidly, unable to cool the cabin, or failing to turn on the compressor, you should replace your AC pressure switch. via

How do you wire an AC fan with a trinary switch? (video)
How do you wire a dual electric fan? (video)
How do you wire a 4 wire trinary switch? (video)
How do I fill my Vintage Air air conditioner? (video)
How can I mess up my AC unit?
Can you flush a parallel flow condenser?
That's because a parallel-flow condenser cannot be flushed – only replaced. Since flushing the system is always recommended when replacing a failed compressor, if your customer needs a new compressor, odds are they'll need a new condenser too. via
How much does it cost to replace an AC pressure switch?
The average cost for air conditioning refrigerant pressure switch replacement is between $247 and $263. Labor costs are estimated between $61 and $77 while parts are priced at $186. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. via
How do you bypass an AC pressure switch? (video)
What happens when AC is overcharged?
Having too much refrigerant in your AC can damage the compressor. This can happen because the excess refrigerant will likely collect inside the compressor and cause subcooling, wherein temperatures are below normal. Furthermore, the extra refrigerant can flood the compressor and damage its mechanical parts. via
What are two types of pressure switches?
There are two main types of pressure switches:
Are AC pressure switches normally open or closed?
The electrical contact of a pressure switch is typically NC (Normally Closed), NO (Normally Open), or changeover. via
Where should a pressure switch be installed?
Installing the pressure switch on the top or air side of these hydro tanks has been the norm. Placing the pressure switch on the air side of the tank eliminates any possibility of hydraulic shock on the pressure switch. Newer systems using bladder type tanks rarely have this option. via
What causes low pressure switch trip? (video)
What would cause an AC clutch to not engage?
Several reasons may cause the AC clutch not to stay engaged. A blown-out fuse, a low-pressure switch lockout, a bad clutch coil, a gap in the wire to the clutch coil, a bad engine coolant temperature switch, or poor ground. via
Which AC port is low pressure? (video)
Does radiator fan come on with AC?
The condenser fan (if it has a dedicated fan) or the radiator fan most always comes in (with AC on) when the compressor discharge pressure (or, alternatively, the liquid line one; look for where a sensor or a switch is located on the high pressure line) rises over an operative threshold. via
How do you wire a dual electric fan to a toggle switch? (video)
What causes low pressure on high side of AC?
For the most part, it could be a component failure, such as a faulty condenser or condenser fan. If either of the latter fails, the AC's refrigerant (or Freon) can't be sufficiently cooled, causing issues with the pressure readings. Or else, it might be a problem with over-gassing with refrigerant. via
How do I know if my AC clutch relay is bad?
Common signs include inconsistent cooling, not hearing a click from the compressor turning on, and no cold air. via
Can you fix a pressure switch?
Because it gets so much constant use, the pressure switch is the most common failure point for a well pump. Fortunately, it is also easy to repair and replace. via
How do you troubleshoot a pressure switch?
If your switch won't turn on, this could be a sign your tank pressure is above your switch's cut-in pressure. Try running some water elsewhere in the building to reduce pressure below the cut-in level. You can also try gently tapping on the pressure gauge, the switch, and the tank. via
