On a good compressor using an ohm meter you should get a positive reading from common?
Well, isn't that a happy little question! When testing a compressor with an ohm meter, you should get a positive reading from the common terminal. This indicates that the winding inside the compressor is intact and functioning properly. Just remember to always refer to the manufacturer's guidelines for specific readings and instructions.

When Taking an ohm reading from the compressor terminals to the condensor housing is a way of checking?
Taking an ohm reading from the compressor terminals to the condenser housing is a method to check for electrical shorts or insulation failures. If the reading shows continuity (a low resistance value), it indicates that the compressor windings may be shorted to ground, which could lead to equipment failure. Ideally, there should be infinite resistance, meaning no electrical connection to the housing. This test helps ensure the safety and proper functioning of the compressor in the refrigeration system.
Can the suction valves and discharge valve on a reciprocating compressor be open at the same time?
No, the suction valves and discharge valves on a reciprocating compressor should not be open at the same time. If both valves are open simultaneously, it can lead to inefficient operation, potential damage to the compressor, and a loss of pressure. The design of the compressor relies on the sequential opening and closing of these valves to ensure proper gas flow and compression cycles.
What should the ohm readings be across the 3 windings of the compressor?
The ohm readings across the three windings of a compressor should typically range between 1 to 10 ohms, although this can vary depending on the specific compressor model. The readings should be relatively close to each other, indicating balanced windings. If any winding shows an infinite resistance (open circuit) or significantly different values, it may indicate a problem such as a short or open winding. Always refer to the manufacturer's specifications for the exact acceptable ranges.
Does a reciprocating replace a scroll compressor?
Yes, a reciprocating compressor can replace a scroll compressor, but there are important considerations. Reciprocating compressors typically have a different operating range, efficiency, and noise levels compared to scroll compressors. While they can serve similar applications, factors like space, vibration, and maintenance requirements should be evaluated to ensure compatibility and optimal performance.
What ohm reading should you have on a crankcase heater?
The ohm reading on a crankcase heater can vary depending on the specific model and manufacturer. However, a common range for a properly functioning crankcase heater is typically between 5 to 30 ohms. It is important to refer to the manufacturer's specifications for the specific heater being tested to ensure accuracy and proper functioning of the equipment.
Should you get a reading between the herm and fan terminals on a dual capacitor?
No, you should not get a reading between the herm and fan terminals on a dual capacitor. The herm terminal is for the compressor and the fan terminal is for the fan motor. Reading between them could indicate a short or a faulty capacitor.
Do you have to have car running when applying freon to ford focus?
Yes, in order for the compressor to take on the new coolant and oil charge the compressor ideally should be running. It is posiible to begin charging the system with freon prior to compressor initiation, however to get an accurate reading of the pressure in the system the compressor should be cycling with differential valve operating properly. If it is clogged or the compressor is not cycling then then low side reading will give an elevated pressure while charging the system. Does that make sense?

What does it mean when r-22 gauge reads the same on the low and high sides of a heat pump?
It means either the compressor is not running, or if you are certain it is, the compressor valves are bad. You can verify this by taking an amperage reading and comparing what you read to the compressor nameplate. If the valves are bad the reading will be significantly lower than they should be. Also the compressor will feel hot to the touch and will cycle on and off on it`s internal temperature protection device.
How do you use an ammeter?
The Positive side of the Ammeter should be connected to the positive side of the battery and the Negative side should be connected to the Globe/Conductor/Insulator to provide a valid reading.
How can you test a air conditioner 3 phase compressor?
just disconnect power & get ur Ohmmeter,and test ; Start-Run//Common-Run//Common-Start..... you should get the same readings on all 3 phases if the compressor is good !!
How do you check mega ohms on compressor?
Usually you check mega-ohms by reading the resistance between compressor shell and the windings. There should be a large amount of resistance which means the windings are not shorted to the compressor case or shell. Use a DVM (digital volt ohm meter) to check the resistance.
What is the voltage reading of positive wire in 110V dc?
You should be asking, 'What is the potential reading of a positive wire....?', as 'voltage' means 'potential difference' and you can't have a potential difference on a wire! The positive wire has a potential difference of +110 V with respect to the negative wire.
What causes the air conditioner to stay hot in a Lincoln Town Car?
The most common reason would be that you are low of R-134a. The best way to determine this is to use a gauge and get the PSI reading. (This should be done when the compressor is running and the clutch is engaged). Most auto parts stores are willing to help you get a reading. If you are indeed low of R-134a you need to fill your system to the correct PSI level. (This is determined by the current ambient temperature) If the compressor is not running you could fill the system with one can of R-134a, the compressor should start short cycling. If it doesn't do not put anymore R-134a in and seek professional help.

What are the symptoms of a bad ac compressor on a 98 Lincoln town car?
The symptoms of a bad ac compressor would be a grinding or rattleing sound or a low pressure reading on the high side with a normal pressure reading on the low side. The low pressure will be about 30 to 40 pounds. The high side should read around 150 to 200.
Do you need two jumpers from your outdoor condensor compressor to the start capacitor if you only have one and does it need 220 or 120 if it is a 40mfd rated for 330v?
Do you have a dual capacitor that starts both the compressor and the fan motor? You need 230V to power the compressor. You should have one wire from the capacitor going from the start terminal on the compressor and one going from the common terminal to common on the capacitor.
