Steve, Two items will cause frequent clicking in the electrical compartment. You either have the original 25 amp cooling fan circuit breaker which would need to be up-graded to a 40 amp. If the 40 amp is installed than you have a low freon charge.

The obvious decrease in power is no longer apparent as the fans cycle on and off but the clicking noise is still there and seems about as frequent as before. Is this the normal operation of the unit or have I installed it incorrectly ? After all, the installation is so easy. Vin 2528
