Table 7: Single Zone Mega Wall Mount System Troubleshooting (Continued)

Issue

Cause

Corrective Action

Unusual noise or vibration during unit operation.

Clicking noise during operation.

A clicking sound can be heard either

when the unit starts or stops due to

movement of the reversing valve.

These are normal noises for the air conditioner as it shifts into

different modes of operation. Once a mode is activated, noise

or vibration should stop.

Creaking sound during operation.

The plastic parts of the indoor unit

make sounds due to shrinkage

and expansion during sudden

temperature shifts.

Water flowing sounds.

Switching of the flow of refrigerant

through the air conditioner produces

water flowing noise.

Unusual odor emits from indoor unit.

A bad odor can emit from the indoor

unit due to mustiness or cigarette odor

being taken in by the indoor unit from

the room it is located in.

If the smell does not disappear, clean the air filter. If the odor \

persists after cleaning the air filter, contact the installing

contractor.
