You need to make sure your condensing fan motor is working properly, condenser coil is clean, if both is proper you could have a weak capacitor or the system could be low on freon.

May be this tripping your compressor,please check the continuity of the following..
1) Continuity of Compressor if this a loose compression
2) Continuity of Capacitor if this a low capacitance or not functioning.
3) Check the power voltage.

Go to the nearest shop for repair the units,thanks

Is the condenser inside the unit

In a window unit the condenser is in the unit and is at the back of the outside section. With a split system or whole house cooling unit the condenser is always outside. The condenser compresses the cooling gas after it picks up heat from the inside evaporator, and forces the heated gas through a coil with a fan blowing through the coil to drive out the heat. A gas can be compressed, but the amount of heat it contains remains constant. A compressed gas will be hotter than non compressed.

Refrigeration is actually a fairly straight forward easy to understand process....

Refrigeration is actually a fairly straight forward easy to understand process. Although there are several ways that refrigeration can be achieved in a system, the most common is vapor compression, in which the compressor is the heart of the system. The temperature of the refrigerant is related to its pressure. For example R134 is roughly -15 degrees Fahrenheit at no pressure. (Thats gauge pressure and not absolute). When compressed to 250 psi R134 is about 148 degrees. 
 Starting from the compressor, the refrigerant vapor is compressed. In the process it will heat up hotter than the surrounding air. As the refrigerant passes through the condenser, heat is given off since it is hotter than the surrounding air and as a result it condense and turns liquid.(thats why it is called a condenser). The liquid refrigerant then passes through an expansion valve or a capillary tube where it turns into low pressure liquid and as it passes through the evaporator  absorbs heat from its surrounding since it is much colder. This makes the refrigerant turn into gas and evaporates (again it is why it is called the evaporator) absorbing tremendous amount of heat. Then refrigerant vapor  passes through the accumulator in which  moisture accumulates ( why it is called the accumulator) before it is sucked into the compressor to be compressed again. (Why do you think the compressor is called compressor? you know the answer by now) 
 The whole system is really a means for heat transfer for removing heat from one place and expelling it outside  in which the refrigerant is the vehicle.  Heat always travel from hot to cold. If something is hotter than the surrounding, it gives off heat and if it is colder, it absorbs heat. Simple as that. There is a thing called latent heat of vaporization or in thermodynamic term it is called enthalpy of vaporization. This simply means when liquid reach its boiling temperature at a constant pressure it will no longer get any hotter. . For example when you boil water at sea level it stay 212 degrees no matter how much heat you put under the pot. You can also think of it as putting heat into it but it is not doing anymore work. since the water is not getting any hotter. If there was meat in there it would not get soft any faster by adding more heat. The water will just absorb all that heat without getting any hotter. That is just one of those wierd law in physics and it is the underlying principle in theory of refrigeration. It is the fact that when liquid evaporates, it absorbs tremendous amount of heat and carries it away. Rub alcohol on your skin and the skin feels cold as the alcohol  evaporates. Thats a simple form of refrigeration at its very basic. 
 There are other types of refrigeration for example another one is called "absorption system". This kind uses heat to vaporize liquid (usually ammonia and water solution) mixed in an absorbing material. as the subtance evaporates it accumulates on the other end as liquid. When heat is taken away, the whole thing cools down and the pressure drops to a point so that the liquid that has accumulated will evaporate and be collected back on the absorbing material. This produce refrigeration. It has no moving parts no compressor and just uses heat. In fact it can be used as ice maker which is ironic since it works by heat. The last one would be thermoelectric. If current is passed through two dissimilar metals one of the metal will get cold at the junction, and it is called the peltier effect. Coolers that plugs into cigarrete lighter are example of these type of device. They are not really very efficient but have some advantages such as it can be used as food warmer when the current is reversed.

I have a Bonaire split aircondition & heating system. When I use remote controll change mode doesn't work heating mode. Other mode are working properly but heating mode doesn't work.

check the ambient temperature as there is most probably a lock out feature that will not allow reverse cycle to work if the system cannot remove the cold from the evaporator
To understand the system , when in cool mode the outside unit is called the condenser and in effect removes the heat trapped by the evaporating gas in the evaporator to the atmosphere
in the heating mode the roles of the evaporator and the condenser are reversed so that the evaporation of the gas in the now evaporator out side is now compressed in the inside unit and the heat from that compression action is released into the room
read the manual for the unit or talk to an ac specialist and have it explained

Will not Heat or Cool

There may be a compressor problem.
Can you detect if the compress is spinning?

What is the a/c compactor?

I think you mean compressor. It is basically the heart of the A/C unit. It compresses and pumps refrigerant through the unit. It compresses it so the outdoor unit will be able to remove heat from the refrigerant.

Compresser is not running

The condenser fan motor is most likely blown. A replacement fan motor and a run capacitor are most likely needed to get it back in working order.

A/c not cooling

it sounds the problem with the compresser.or may be ur compresser is getting heated quickly and stops working which stops cooling.

Motel style heat and air

Meaning not function of heating,pls apply this the following 1) Possible loose connection to reversing valve pls check this wiring connection.
2) Pls check the sensor to thermostat if this a loose connection.
3) Check the Compressor if this not function or loose compression.( Function but not heating )
4) Check if have a Leakage.

Pls go to the nearest repair shop if not solve,

Thanks & best regards,
