If the freon in the system gets too low, the low pressure cut off switch won't let power go to the compressor clutch to protect the compressor. You need to have a shop diagnose the AC system possibly just needs a recharge but the system could also have a leak.

Freon was full according to tester he said there's no click when A/C is engaged. Appears that no electrical power is getting to clutch so it can engage.

It "appears", could you explain what that means? It appears your "tester" doesn't know how to test!
