This  TSA  workshop  is  designed  for:

• HVAC/R Technicians
• Maintenance Techs who service Air Conditioning / Refrigeration and Heating units and Furnaces

This workshop employs a real-world systems approach to trouble-shooting HVAC Electrical Systems, which begins with a look at the various types of circuit breakers and fuses that protect HVAC systems.  Using multi-meters, participants will trouble-shoot fuses and breakers with the emphasis on what to do if there is no electrical power to the HVAC system.  Next, the workshop will cover electrical diagrams for central air and heating systems, room air conditioners and heating units, and self-contained central systems.  The emphasis will be on how to read the diagrams so that the trouble can quickly and correctly be determined.  As each item on the diagram is covered, workshop participants will take the part in hand, determine what to check and how to check it, and find out what meter reading indicates that it is defective.  This clear and concise training session is about what to do, and how to do it  with HVAC electrical trouble-shooting.

The majority of service problems in air-conditioning systems, heat pumps, and gas and electric furnaces are related to electrical situations.  Participants at this workshop will have opportunities to learn electrical trouble-shooting from the ground up, and they will learn how to put the information they learn to work with actual “hands-on” experience with real-life testing situations.

Participants are encouraged to bring their own diagrams that they would like the workshop leader to help them with to the workshop.  Each participant will be issued a digital multi-meter, which they will learn to use during the workshop, and then take home with them to use when doing future servicing. Everyone who attends this workshop will also be presented a TSA certificate of training.

 Agenda

First and Second Days: 8:00 am – 5:00 pm

Third Day: 8:00 am – noon 

Major topics that will be covered during this training:

• Electrical safety, test instruments, and safe work practices
• Electrical power distribution within a facility
• Electrical voltage, amperage, resistance, and work
• Trouble-shooting fuses and circuit breakers
• Testing hot, neutral, and equipment grounded conductors
• HVAC electrical diagrams – schematics and ladder types
• How electrical loads such as motors, compressors, and heaters use electrical energy
• How electrical relays & contactors pass power in a circuit
• The art of trouble-shooting

HVAC System Electrical Parts That Will Be Tested:

• Electrical circuit breakers
• Compressor contactors
• Electric heating element sequencers
• Compressor starting contactors
• On-off delay timers
• Space thermostats
• Control transformers
• Starting and running capacitors

Upon completion of this workshop participants will be able to:

• Demonstrate how to safely check electrical circuits using a multi-meter
• Determine if a circuit breaker has tripped open or is operating properly
• State 2 conditions that cause an over-current device to open the circuit
• Understand why amperage is a measure of work and voltage is a measure of potential to do work
• Explain how a ladder diagram is used to trouble-shoot a HVAC system
• Determine if a motor is loaded or overloaded

Additional topics that will be covered during the workshop:

• Recording data so that replacement parts can be ordered
• What information is on the unit’s nameplate and why it is important
• Why on-off delay timers may be needed on single phase compressors
• How to select a replacement fan or blower motor
• Air distribution systems components
• Thermostat types placement and adjustment
