Many new self-contained fractional horsepower refrigeration systems will be shipped from the factory with no service access ports.

There are many ways to waste time on a repair, but one of the more common ways is not having what you need to finish the job.

As more refrigeration systems incorporate electronic controls into their design, it is important for technicians to be able to troubleshoot these electronic devices, such as the pressure transducer.

During the installation of a new walk-in cooler or freezer, it is imperative the box remain square and level during the assembly of its panels.

Occasionally while servicing refrigeration equipment, technicians may come across a system utilizing a water-cooled condenser instead of an air-cooled condenser.

When replacing an older mechanical temperature control, an option for some systems is to replace the older control with a newer electronic version.

Recently, I ran into a scenario where what I thought would be an easy repair ended up being quite a challenge.

A defective tool can lead you in the wrong direction as you try to determine the root cause of a problem.

When electrically inspecting or troubleshooting a compressor, you should always protect yourself against the possibility of terminal venting.

Lack of following these general piping guidelines will result in either a failed compressor or a system not operating at its rated capacity.
