The motor in water coolers is the most sensitive part that breaks down for various reasons. In many cases, repairing the water cooler motor is expensive, and if the motor burns out, there is no other choice but to replace the motor. The following are among the common reasons for the water cooler motor not turning on, which are often easily fixed, and if they are detected early, more serious problems can be prevented for the cooler motor.
Incorrect adjustment of engine strap
In water coolers, the belt acts as an intermediary between the pulley (pulley) and the motor and transfers the engine's driving force to the pulley. This force eventually causes the rotation of the large money and cooler blades. Incorrectly adjusting the tension of this belt on the pulley and the motor, to the extent that the belt is loose or too tight, it eliminates the possibility of the pulley and the motor moving and prevents the water cooler motor from starting.
Inadequate location of the water cooler
Water coolers are often installed on the roof. This place exposes the cooler to direct sunlight, wind, rain and snow. Strong sunlight by increasing the temperature of the environment around the cooler can cause severe pressure on the engine and ultimately, it will burn.
Using a water cooler canopy that fits the dimensions of the cooler and can protect all parts of the cooler from the sun's rays. Avoiding the middle hours of the day in hot seasons plays a very effective role in preventing serious damage to the water cooler engine.
Blue Fuse Fuse
Fuse is one of the important and vital parts in water coolers, which prevents damage to the motor in the event of a sudden increase in the voltage of the electric current. A broken fuse or so-called blown fuse can be the reason why the water cooler motor does not turn on.
Since this part is located near the cooler motor and any tampering with it without expertise can lead to accidents and electrocution, we strongly recommend it. Leave the health check of the water cooler fuse or its replacement only to experts.
Cooler
The motor of the water cooler burns out due to reasons such as power fluctuations, not having regular annual service, not performing lubrication, the temperature of the environment around the cooler is too high, or even the end of the useful life of the motor. A semi-burning engine usually does not have the ability to start, and even if it does, it will not provide the expected performance. In this case, the cooler motor will burn completely if not treated immediately, and you will have no choice but to replace it.
Blue air conditioner
The breakdown of the on and off switch of the cooler is the easiest reason for the water cooler not turning on. These keys are responsible for connecting and disconnecting the electric current to the engine, and in case of damage, the electricity will not reach the engine and as a result, the cooler will not turn on.
Problems related to the water cooler capacitor
In models with a starting capacitor, this part acts as a source for temporary storage of electrical energy and by receiving electricity and sending it to the engine, it causes the engine to turn on and take off in a short period of time.
Cooler power cord failure
The decay or interruption of the power cord of the cooler causes the power to not reach the motor and as a result, the water cooler does not turn on. This problem usually occurs due to placing the cooler in the wrong place or not installing a canopy for the cooler, wear and tear due to the long life of the water cooler, poor quality wiring of the cooler, and... Damage to the motor of the cooler or electrification of the body greatly increases, it is better to have the cooler with this problem checked by a specialist and replace the rotten wiring as soon as possible.
The connection of the electricity to the cooler body
Sometimes, due to reasons such as rotting electrical connections, not using an earth wire for the cooler, problems with the distribution box, connecting the water pump or splashing water on the cooler motor due to the failure of the water supply system inside the cooler or the rupture of the water hose, the body of the cooler is electrified.
< Although all the mentioned reasons can cause the connection of electricity to the body of water coolers, in most cases, this problem is caused by water splashing on the motor. This defect does not exist in gas coolers due to not needing water, and one of the reasons for the superiority of these types of coolers over water models is this advantage.
Cooler engine coil breakdown
The power required to start and start the water cooler motors is provided by the coil, and any problem in the coil will prevent the water cooler motor from turning on. The poor quality of the iron core of the coil, overheating of the coil due to the low percentage of copper, power fluctuations and the use of poor quality wires in the coil are among the reasons that cause the coil of the cooler motor to burn and fail.
Problem in a blue air conditioner speed adjustment system
The engine of all kinds of water coolers works in two slow and fast speeds. The optimal performance of the engine at these two different speeds depends on factors such as the correct adjustment of the engine speed belt, the health of the engine coil, conversion switch and cooler switch. If any of these parts are not in good condition, the cooler motor will not turn on, or if it does, it will only work in slow mode and will not be able to provide the expected distance.
Not adjusting the speed system in the motor of water coolers, in addition to the mentioned problems, It causes malfunction of the water pump, disconnection and connection of the electric current in one of the fast or slow modes, turning on the engine only in the fast or slow speed and being off in the other mode, producing a strange sound or burning smell. So it is better to fix this problem as soon as possible after the repairman diagnoses it.
