What is a contactor for a Central Air Unit?
The relay actuated by the thermostat which starts and stops the compressor and condenser fan in the outdoor unit.
What is a contactor coil?
a contactor is generally looks like a small box connected to an electric circuit. it is what controls electricity flow to a motor. in the middle is normally a way to push in the contactor to manually check to see if either the motor works or if you have electricity.
What is wrong if a old ac unit never shuts off when thermostat is in auto do you think its the relay?
The AC unit is fully controlled by the contactor. If the unit turns off by thermostat control such as setting tstat to off, the contactor is ok. The thermostat could be the problem though. yeah i understand that but when i say old unit i mean its so old that the thermostat only have two cables the red one and the white one! the auto and cont the unit has it in the indoor unit!!!
Where is the AC condenser unit located?
The AC condenser unit is located right in front of the radiator.
How do you fix a 12000 btu Goodman AC split unit if the evaporator starts but the condenser contactor coil is not getting the 220v supply when you turn it on?
You dont say if the the contractor pulls in ? IDoes it? Three AC servicemen could not repair this same problem last year. These were very experienced servicemen and they had the same problem you have here - if you are stating it correctly. The condenser contactor coil - also called a relay coil is supplied by a 24 volt supply via the thermostat in simple systems. It tells the relay out in the condenser unit to connect the 220 volt feed line to the compressor. That sugger is going to come on. Your facts are wrong or your 220 volts is not on the relay input.
Why does the air conditioning compressor keep operating long after the system is turned off?
The contactor on the outdoor unit is probably stuck. Disconnect the power to the indoor unit, then disconnect the power to the outdoor unit and take a look at the contactor.

What could be the problem on an air handling unit controlled by a three phase motor with two speed settings low and high that is tripping out its high speed contactor?
With this type of installation there should be two magnetic contactors for each speed. Check the full load amps of each speed of the motor and set the corresponding heaters of the respective contactor for the amperage of that speed.
What the reason for Compressor and condenser fan not starting?
ONLY COMMON POINTS TO BOTH ARE: LINE VOLTAGE TO COND. UNIT;FUSES, BREAKERS, DISCONNECT. LOW VOLTAGE TO CONDENSING UNIT CONTACTOR COIL; WIRING, T-STAT (NEED POWER COMING FROM Y and C), (24vac) in a call for cooling. CHECK FIRST AT AHU OR FURNACE CONTROL BOARD. JUMPER FROM R and Y to bypass t-stat. DO NOT JUMPER FROM "C" TO ANYTHING, THIS WILL BLOW FUSE OR TRANSFORMER. CONTACTOR (I'VE FOUND BUGS STUCK IN CONTACTS TOO) lc
