In this HVAC training video program, Jim Johnson follows up on "Deciding Where To Begin" (VID 319-01 with specific component tests technicians can perform to determine the specific failure that is the cause of general complaints of "not cooling", "not blowing air" or "no heat."
Specific Tests Covered In This DVD Are:
...Testing transformers.
...Testing contactors.
...Testing potential relays and start capacitors.
...Testing compressor motor windings.
...Testing multiple speed fan motors and fan relays.
...Testing thermostats.
...Testing gas valve coils.
You can use this video as an independent study guide, or it can be used in conjunction with an available Instructor's Guide that contains transparencies a facilitator can use on an overhead projector, along with instructor notes and instructions on how to present additional information to technicians while conducting an in-house training session. Interactive technician/student workbooks that are intended for use during an facilitator-led training session are also available.
