Learn Refrigerator Repair
Master The Cooling Loop
Demystify the physics of cooling. If you want to learn refrigerator repair correctly, you must understand the entire thermodynamic cycle. From modern Inverter Compressors to classic Defrost Circuits, learn to determine if it’s an electrical failure or a sealed system issue.

Is It The Compressor or The Board?
Refrigeration is about heat removal. To learn refrigerator repair effectively, you have to distinguish between airflow restrictions, defrost failures, and major system failures. We teach you the “Process of Elimination” so you don’t misdiagnose the problem.
Defrost Systems
The #1 cause of “Warm Fridge / Cold Freezer.” Learn to troubleshoot the heating element, the bimetal termination thermostat, and the Adaptive Defrost Control (ADC). Learn how to force a manual defrost to prove your diagnosis instantly.
Inverter Inputs
Inverters aren’t magic. They just need the right signal to run. We teach you how to test the input voltage (DC) and frequency signal cables (Hz) to ensure the inverter is getting exactly what it needs to work.
System Isolation
Stop guessing. We teach you the diagnostic steps to definitively determine if you are looking at a sealed system leak/restriction, or if it is purely an electrical component failure. Never condemn a good compressor again.
Diagnostic Strategy
Sealed System Identification
This course focuses on electrical and component diagnostics. However, understanding how to identify a sealed system failure is critical so you don’t waste time troubleshooting control boards on a unit with a gas leak.
We teach you to read “Frost Patterns.” A full frost pattern means the system is healthy. A partial frost pattern is the smoking gun of a refrigerant leak. We teach you to spot the difference in seconds by inspecting the evaporator coil.
- ✓ Interpreting Partial Frost Patterns
- ✓ Compressor Amperage Signatures
- ✓ Condenser Heat Transfer Checks
Electrical Analysis
Fans, Relays & Sensors
Modern refrigerators are full of DC fans and NTC sensors. Learn to diagnose if the board is sending the correct voltage, or if the component itself has failed.
When you learn refrigerator repair with ATA, you learn to trust your meter. We teach you how to condemn a bad main control board through a strict process of elimination, verifying inputs and outputs before you order expensive parts.
