Notes: This guide was prepared with standard equipment in mind. If equipment is special, it may not be entirely applicable. If equipment is still in warranty. Notice: Before trying to correct the noise, determine its cause: conditioned air blower, compressor or condenser blower. Operate the conditioned air blowers only. If this doesn’t cause the noise, operate on cooling. Then disconnect one compressor lead. If the noise stops, the compressor is the source, If not, it is caused by the condenser blower.
