What to do if my Bosch BMS500-AAM027-1CSXHB operation is erratic?
If your Bosch Air Conditioner is operating erratically, it might be due to interference from cell phone towers or remote boosters. Try disconnecting the power and then reconnecting it. Then, press the ON/OFF button on the remote control to restart the operation.
Why does my Bosch Air Conditioner unit emit a bad odor?
Your Bosch Air Conditioner might emit a bad odor because it has absorbed smells from the environment, such as furniture, cooking, or cigarettes. Alternatively, the unit's filters may have become moldy and need cleaning.
Why does my Bosch BMS500-AAM027-1CSXHB Air Conditioner change from COOL/HEAT mode to FAN mode?
Your Bosch Air Conditioner might switch to FAN mode to prevent frost from forming on the unit. Once the temperature increases, it will resume the previously selected mode. Also, this can happen when the set temperature has been reached, causing the compressor to turn off. The unit will continue operating when the temperature fluctuates again.
Why is dust emitted from my Bosch BMS500-AAM027-1CSXHB Air Conditioner?
If dust is emitted from your Bosch Air Conditioner, it may have accumulated during a long period of non-use. This dust is then emitted when the unit is turned on. To mitigate this, cover the unit during long periods of inactivity.
Why does my Bosch BMS500-AAM027-1CSXHB make noises?
A rushing air sound may occur when the louver resets its position in your Bosch Air Conditioner. Also, a squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit’s plastic parts.
Why do both indoor and outdoor units of my Bosch BMS500-AAM027-1CSXHB Air Conditioner make noises?
A low hissing sound during operation of your Bosch Air Conditioner is normal and is caused by refrigerant gas flowing through both indoor and outdoor units. A low hissing sound when the system starts, has just stopped running, or is defrosting is also normal, caused by the refrigerant gas stopping or changing direction. Squeaking sounds can be caused by normal expansion and contraction of plastic and metal parts due to temperature changes during operation.
Why does my Bosch BMS500-AAM027-1CSXHB indoor unit emit white mist?
In humid regions, a large temperature difference between the room’s air and the conditioned air can cause white mist to be emitted from your Bosch Air Conditioner.
