all it is is a switch that you will usually find 4 wires coming out of. how it works is you get a call for cooling from ur air conditioning unit and that sends a 24v signal to the contactor and it closes the curcuit and gives power to you condencer. control device to relay power to a load

Does an air conditioner condensing unit with a two-speed fan require a two-stage thermostat?
No!
Condensing unit for heat pump unit making knocking noise What causes my heat pumps condensing unit to making knocking noise?
There could be loosened internal mounts (connecting rods, pistons, pins, crankshafts or other related parts) in the compressor causing the banging or knocking noise. A simple call to a technician should resolve the issue.
What is difference bw condensing and non condensing steam turbines?
A condensing turbine uses all the energy from the steam going from high pressure turbine to secondary turbine to condensing turbine then sends the condensate back for reheating. where a non condensing turbine just uses the high pressure aspect of the steam then returns the low pressure stream back to be reheated. Condensng turbines utilises the entire available drop from high pressure to the vacuum in the condenser; a back pressure turbine only utilises only the top part, whereas an exhaust steam turbine utilises only th bottom part of the pressure drop. Hope that helps.
Why low vacuum trip in condensing type steam turbine?
To protect the mechanical integrity of the unit. The condenser is not designed to hold a pressure and as such must be prevented from any positive pressure above atmospheric. Often rupture discs are fitted as a mechanical prevention against any pressure surge.
Can you replace your straight cool AC condensing unit to a same size unit with heat pump?
Hi, Good question and the answer is ( YES! ) as long <<<< as you are not taking up any fancy ideas of using it as a heat pump. Wire it in and set the reversing valve to stay on cool cycle and never reverse to heat and viola. Some units use energized reversing valve during cool and some de-energized. Its easy to find out. Just try it. Hope this helps: Jimiwane
What device is the only load in the control circuit of a condensing unit?
I think that would have to be some relay or contactor coil for a fan, compressor or relay contacts.
How does the sunshine affect the operation of a condensing unit?
It does Not effect on the operation of a condensing unit
What is the cost to replace a 3 ton condensing unit?
just the condensing unit roughly 1500to2000
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.
Condensing unit wobbles?
A condensing unit should not wobble. If it does wobble, it can lead to issues such as broken lines. It could also cause the compressor to stop working.
What is the average price to replace a condensing unit?
It depends on where you live. Max rate is 90 an hour plus parts. A res. condensing unit up to 5 tons should be about 1500.
What is the seer rating of a heil condensing unit model number n4a34bgkb200 and is this a heat pump?
This is a straight cool 13 SEER condensing unit that uses R410a refrigerant. This is not a heat pump.
How do I find BTU in tons of air condtion unit?
It`s found in the condensing unit model #.
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
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.
If a condensing unit is out of level or wobbles watch for?
stress on the refrigerant lines
What is the tonnage of a goodman condensing unit CK36-10?
It is a 3 ton.
