WHAT TO DO Firmly plug power cord into electrical outlet. Check circuit voltage at fuse/circuit breaker box. Replace fuse with a time-delay fuse of the correct capacity. Reset circuit breaker. Set System Control to another setting. Wait for power to be restored. Replace fuse with a time-delay fuse of the correct capacity. Do not use an extension cord with this or any other appliance.

Normal operating sounds . . .
When your room air conditioner is operating normally, you will hear sounds such as: l Droplets of water hitting the condenser, causing a �pinging� or �clicking� sound. Water droplets help to cool the condenser. l Air movement from the fan, especially on HI COOL setting. l �Clicks� from the cooling cycle. Sounds also may be caused by house construction - such as vibration of the unit due to wall construction or unsteady window mounting area.
