HVACR Troubleshooting Fundamentals: 30 Electrical, Refrigeration & Air Flow: Troubleshooting Scenarios PowerPoint Bundle
This PowerPoint bundle includes both the HVACR Troubleshooting Fundamentals: 15 Electrical Troubleshooting Scenarios PowerPoint and the HVACR Troubleshooting Fundamentals: 15 Refrigeration Systems Troubleshooting Scenarios PowerPoint.
These troubleshooting PowerPoints give HVACR instructors, service managers, and trainers the opportunity to help develop their student's/technician's troubleshooting skills in a PowerPoint presentation format.
Electrical problems presented include:
A heat pump that's not keeping a building comfortable;
A comfort cooling system that's not performing like it should;
A no heat complaint;
An electric furnace that's not keeping a house warm enough;
A two-stage air conditioner that's not working;
A small commercial unitary system that's not heating;
A split system that's blowing fuses;
A condensing gas furnace that's not heating;
A package unit that's not cooling;
The excessively expensive heat pump;
An electric furnace that's not heating enough;
A system that's blowing warm air… a no cooling complaint;
An ice machine that's not dispensing cubes properly;
A comfort cooling system that's not keeping up with the load.
Refrigeration system problems include:
Normal refrigeration pressures, a sweating suction line, and excessive current draw;
Lower than normal system pressures and compressor current draw that's far below normal;
Lower than normal pressures and a higher than normal current draw;
System pressures lower than they should be and a low current draw;
High side lower than normal and low side in a vacuum;
Vacuum on the low-pressure side, high side higher than normal;
Low side pressure in a vacuum, high side pressure slightly higher than it should be, current draw lower than normal;
Differential between low and high side pressure side of the system are closer together than they should be;
High side pressure higher than it should be, current draw of the compressor excessive;
Equipment with a history, customer's complaint is that the house is always sticky;
A follow up on a heat pump reversing valve replacement;
A customer's complaint that the house just isn't as comfortable as it should be;
A rooftop air conditioner that doesn't keep the store comfortable on hot days;
A new installation of a comfort cooling system in a ranch style home;
A follow up on a compressor diagnosis.
Answers to the troubleshooting scenarios are presented on a separate slide in the PowerPoint which will allow the instructor/trainer to present the problem along with details of the scenario, have class interaction, and then display the answer. This is a great way to engage your class and improve their critical thinking skills!
