A Few Jobs From One Site

This is one of my regular sites. Last maintenance I was told of a few different issues that had come up but the weather prevented me from investigating. Went back a few days later.
Job 1: Leak search on a MHI high wall split.
Job 2: Repairing a leaking flashing from a roof penetration.
Job 3: Investigating an OPA 550 Temperzone package unit which was going into defrost frequently.
I have an Instagram page where I post other content: @hvacr_tech_aust

With the newer version 4 uc8 boards, they will go into a lockout if a fault repeatedly happens and will stay in lockout even if the unit is power cycled. You clear the lockout by holding down the SW3 button for around 10 second’s. The older version 2 uc8 a lockout could be cleared by a power cycle.

Best way ive found to remove silicone is mini wire brush attachment for your impact. Brings it back like new in seconds.
