The external fan is cutting off when the unit is operating in hot temperatures. The blades stop spinning and the cool air stops blowing.
It seems to have a problem operating in temperatures over 38 degrees celsius. No errors are displayed on the unit inside when this happens. Its just noticeable as the temperature inside starts to rise. Is the unit over heating? Is there a switch that gets tripped at a certain temperature which is causing this?
I thought that these units were designed to operate in hot temperatures as that's when they are required. Has any one got any helpful advise?

Tip: The max point reward for answering a question is 15.
Your question does not include what type of system you are asking about, but the assumption is that it is a heat pump. The loud humming is the compressor running by itself while the fan is off.
This is the typical way a reasonably new heat pump operates:
There is a coil temperature sensor that initiates a defrost period to eliminate the frost/ice build up on the outdoor coil. In the defrost mode, the outdoor fan shuts off and the reversing valve in the heat pump reverses the direction of refrigerant flow to warm the outdoor coil. The same coil temperature sensor senses the temperature of the external surface of the coil and tells the defrost control when the frost is gone initiating another 'reverse cycle' to put it back into heating mode. In the heating mode, the outdoor fan runs again.
If you have the heat pump installed where snow drifts accumulate, you will have a problem extracting heat from the outdoor air, and coil frosting and freezing will be exaggerated. If you have excessive ice build up due to a defosting issue, the ice can actually stop the fan from rotating, but you would hear loud bangind and rattling for hours first as the fan blades come in contact with the ice.
If you do not have drifts, but continually have an excessive amount of ice build up, either the sensor is possibly faulty or the defrost control board is faulty. The sensor's clip could easily have been knocked loose from the coil by ice and is no longer sensing coil temperature and if so the result would be the lack of defrost initiation.
Hi, The overload opens to protect the compressor. It operates in relation the internal or external temp of the compressor, not pressure. With this being said, is or has the compressor ran hot or in a location where temperature increase is possible? I installed a unit in my work van and had a similar issue. I even know better, so in order to control heat I have to install a fan to cool down the compressor. To help you the issue is heat, cooling the compressor will be the only fix if you didn't already do the damage to the compressor. Good Luck
Maybe the beer inside is cold enough to drink, but the green led that indicates it's ok, doesn't light on. So the thermostat may be not operating well or the ambient temperature is too hot. My beertender B100 is operating without turning compressor off. The compressor never stops operating... even when external temperature is under 26 C... but the beer temperature is ok.
often be part cools the processor and take out the hot air from
the laptop has been suspended by some dust and other and then back hot
air into the Laptop exceeded the level of temperature and it is based
laptop stop to protect the processor in this case has to be clean this
part well inside a process need to be an expert and you can always use
an external fan placed underneath This is temporary and
must be clean and refrigerator always change the fan if necessary. You
can find and external cooling unit is available in many stores and there
are many shapes and types.finally remove any usb devices that connected in you pc and tray again &tray by another charger

Yes you can BUT.... you will need to use an external fan directed at the rear of refrigerator with the fiberboard cover removed. If you do not use an external fan the chassis of the refrigerator will get hot to the touch and the freezer will warm up. Ice-maker will probably stop working and ice-vream will get soft due to the rise in freezer temp. Just use a small external fan directed at the condensor coils and it will work fine until you get a new fan. There is the possibility that you might get an error code saying the condensor fan is open. You made no mention of a model number and the more advanced units will error. If you experience this error problem... just remove the fan blade and let the motor run BUT you will STILL have to use an external fan until you get a new fan blade.
I love the 02 Cool rechargeable/battery operated fans and have them running in my home and office daily. However, they do have a limited lifespan. I get about 6-9 months of daily use before the fan motor goes dead and the blades stop turning. However, I'll keep buying them. I live in an area where we frequently lose power and the rechargeable/battery operated feature pays off when it does so on a hot day.
