Stay on a real pathway
Residential, Commercial Refrigeration, Full Diagnostic, and Technical Systems tracks.
Certificates are FixGrid Academy skill-track certificates, earned by completing the labs and modules in a track. They are not a licence and not an official industry certification.
Appliances and commercial refrigeration have gotten more electronic, not simpler.
Inverter compressors, control boards, and sensor-driven sequences mean guessing costs money. What holds up is structured practice in technical judgment — interactive labs, real service scenarios, and graded decisions that show you where your reasoning breaks down before a customer does.
The focus is steady
Diagnose accurately, repair once, and back it up with verifiable proof of skill.
Practice judgment, not just theory.
Step onto a real service call, clear the safety gate, and choose your next test. Branching scenarios with graded decisions, corrective feedback, and a Maya AI tutor beside every step — built for technicians, supervisors, and engineers who need to keep their diagnostic reasoning sharp.

Safety gate
Diagnosis stays locked until the machine is safe.
Branching choices

Why train with FixGrid Academy
System Understanding
Build a working knowledge of motors, pumps, sensors, control boards, inverters, sealed systems, and wiring — the real building blocks of household appliances and commercial refrigeration.
Diagnostic Method
Learn a repeatable process that narrows a complaint systematically, confirms root cause with measurements, and supports sound repair-or-replace decisions in the field.
Sequence and Control Logic
Understand what a machine is supposed to do and in what order, then compare expected sequences against actual behavior instead of swapping parts.
Practical Diagnostic Judgment
Graded labs and corrective feedback that build the judgment to call it right on a fridge, ice machine, walk-in, or rooftop unit under real service pressure.
Technical Systems Curriculum – 16 Modules
A complete professional path designed to raise the standard of field technicians:
- Deep component and system knowledge
- Structured diagnostic method
- Machine sequence training
- Integrated troubleshooting
- Real-world application focus
Depth matters because the equipment keeps getting more electronic.
This curriculum develops applied judgment for appliance and commercial refrigeration work.
Training that covers the equipment you actually get called on
FixGrid Academy puts you on the call: you clear the safety gate, choose the next test, and work through the result. Residential laundry and refrigeration, commercial refrigeration, and rooftop units are covered in the same measured, evidence-first process — so your method holds up no matter which machine you're standing in front of.
Interactive labs, not lectures
Scenario-based practice where you decide the next test. Wrong turns get calm coaching that reinforces the reasoning you will use in the field.
Verifiable certificates
Finish a learning path and receive a skills-based certificate with a unique credential ID anyone can verify publicly.
Residential + commercial paths
Residential Technician, Commercial Refrigeration, or the Full Diagnostic Technician path covering ice machines, walk-ins, reach-ins, and RTUs.
Documented, verifiable professional capability
Complete the labs in a track and earn a skills-based certificate with a credential ID anyone can verify — a clear record of the judgment you have demonstrated.
Residential Technician Path
Certifies structured diagnosis of the three complaints that fill a residential schedule — no drain, no heat, and no cooling. The track proves a repeatable order of operations: confirm the complaint, rule out the cheap causes, then prove the component with a measurement before condemning it.
View trackCommercial Refrigeration Path
Certifies the judgement commercial refrigeration demands: separating airflow, defrost, and sealed-system faults on ice machines, walk-ins, and reach-ins, using measured conditions rather than a parts swap.
View trackFull Diagnostic Technician Path
The broadest credential FixGrid Academy issues for scenario-based diagnostics. It certifies measurement-driven fault isolation across residential laundry and refrigeration, commercial refrigeration, and packaged rooftop equipment.
View trackTechnical Systems Technician Path
The Academy's deepest credential. It certifies component-level understanding across motors, pumps, sensors, protection devices, control boards, wiring, inverters and system controls, a repeatable diagnostic method, and the ability to read machine sequences and locate a fault at the stage where it occurs.
View trackFixGrid Academy — Connected Appliance Diagnostics
Certifies the method current appliances demand: identify the unit exactly as printed, classify the control, read every software version, check the bulletin before replacing a board, apply the correct brand update path, and only then test the component. Covers GE, LG, Samsung and the Whirlpool group, plus cross-category clinics and a mixed-fault capstone.

Technicians earning more after the Academy
"The inverter and start-relay lab changed how I approach a no-cool call. I stopped guessing at compressors and my callbacks dropped."
"Ran three techs through the labs. Fewer callbacks, faster diagnostics, and the verifiable certificate gives customers real confidence."
"I had zero experience six months ago. Practising the labs with Maya answering my questions in the field made me job-ready in eight weeks."
