If your MrCool Air Handler is operating erratically, unpredictably, or is unresponsive, it might be due to interference from cell phone towers or remote boosters. To resolve this, try disconnecting the power and then reconnecting it. You can also try pressing the ON/OFF button on the remote control to restart operation.
Why do MrCool DIY emit a bad odor?
If your MrCool Air Handler emits a bad odor, it could be due to a couple of reasons. The unit might have absorbed odors from the environment, such as furniture, cooking, or cigarettes, which are then emitted during operation. Another possibility is that the unit’s filters have become moldy and require cleaning.
Why do MrCool Air Handlers change to FAN mode?
If your MrCool Air Handler changes from COOL/HEAT mode to FAN mode, it could be for a couple of reasons. Firstly, the unit may change its setting to prevent frost from forming. Once the temperature increases, the unit will start operating in the previously selected mode again. Secondly, once the set temperature has been reached, the unit turns off the compressor. The unit will continue operating when the temperature fluctuates again.
Why is dust emitted from MrCool Air Handlers?
If dust is emitted from your MrCool Air Handler, it may have accumulated during extended periods of not being used. This can be mitigated by covering the unit during any long periods of inactivity.
Why do MrCool DIY make noises?
A low hissing sound during operation of MrCool Air Handler is normal and is caused by refrigerant gas flowing through both indoor and outdoor units. Also normal is a low hissing sound when the system starts, has just stopped running, or is defrosting. This noise is caused by the refrigerant gas changing direction or stopping. Squeaking sound is caused by normal expansion and contraction of the plastic and metal parts due to temperature changes during operation.
Why do MrCool DIY Air Handlers emit white mist?
In humid regions, a large temperature difference between the room’s air and the conditioned air can cause a white mist to occur. When the unit restarts in HEAT mode after defrosting, a white mist may be emitted due to moisture generated from the defrosting process.
Why does MrCool Air Handlers indoor unit make noises?
The sound of rushing air may occur when the louver resets it’s position. A squeaking sound may occur after running the unit in HEAT mode due to the expansion and contraction of the unit’s plastic parts.
