Troubleshooting
Issue: Unit does not turn on when pressing ON/OFF button
Possible Causes: The Unit has a 3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off.
Issue: The unit changes from COOL/HEAT mode to FAN mode
Possible Causes:
- The unit may change its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating in the previously selected mode again.
- The set temperature has been reached, at which point the unit turns off the compressor. The unit will continue operating when the temperature fluctuates again.
Issue: The indoor unit emits white mist
Possible Causes: In humid regions, a large temperature difference between the room’s air and the conditioned air can cause white mist.
Issue: Both the indoor and outdoor units emit white mist
Possible Causes: When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.
Issue: The indoor unit makes noises
Possible Causes:
- A rushing air sound may occur when the louvre resets its position.
- A squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit’s plastic parts
Issue: Both the indoor unit and outdoor unit make noises
Possible Causes:
- Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units.
- Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise is normal and is caused by the refrigerant gas stopping or changing direction.
- Squeaking sound: Normal expansion and contraction of plastic and metal parts caused by temperature changes during operation can cause squeaking noises.
Issue: The outdoor unit makes noises
Teco Inverter Air Conditioner Manuals
Possible Causes: The unit will make different sounds based on its current operating mode.
Issue: Dust is emitted from either the indoor or outdoor unit
Possible Causes: The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.
Issue: The unit emits a bad odor
Teco Inverter 7300cv Manual
Possible Causes:
- The unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.) which will be emitted during operations.
- The unit’s filters have become moldy and should be cleaned.
Cleaning Your Air Filter
A clogged air conditioner can reduce the cooling efficiency of your unit, and can also be bad for your health. Make sure to clean the filter once every two weeks.
1. The air filter is under the top air inlet grill.
2. Grip the tab on the end of the filter, lift it up,then pull it towards yourself.
3. If your filter has a small air freshening filter, unclip it from the larger filter. Clean this air freshening filter with a hand-held vacuum.
4 Clean the large air filter with warm, soapy water. Be sure to use a mild detergent.
5. Rinse the filter with fresh water, then shake off excess water.

7. When dry, re-clip the air freshening filter to the larger filter, then slide it back into the indoor unit.
