Domestic Appliance Technician VS Appliance Service Technician: What's the Difference?

 An information session at Herzing College in Toronto

Household appliances bring our lives such comfort and convenience, it's hard to imagine a world without them.

Most of the self-contained electric and gas-powered appliances that we rely on each day were invented in just the last century. They have done wonders to increase our recreation time and make our lives so much easier.

Many people don't think much about their home appliances until something goes wrong and they have to call an expert for repairs. Faulty appliances can create higher energy consumption or even become dangerous.

Service professionals make the necessary repairs to give your appliances their maximum life, so they can run efficiently, effectively, and safely.  

If you enjoy working with your hands and are good at solving problems, there are rewarding careers available in the appliance technician trade.

Read on to learn about the similarities and differences between two great career paths: domestic appliance technician and appliance service technician.


What do Appliance Service Technicians do?

Appliance service technicians repair, maintain, and install various types of appliances and other household products. These include:

  • Washing machines and dryers
  • Dishwashers
  • Ovens, ranges, and other cooking units
  • Refrigerators and freezers
  • Microwaves

They may be self-employed or work for service companies, appliance sales companies, apartment complexes, or wholesalers.

House calls are often a part of the job, which means making a thorough inspection of the problem and using your expertise to quickly figure out how to fix it.

Servicing larger appliances takes a certain amount of physical strength and stamina, because you may have to move equipment out from the wall or work in cramped spaces.

A good attitude and communication skills are essential for house calls. Quickly and effectively doing your job while maintaining a pleasant manner will help to ensure repeat business and referrals.

Installing and fixing major appliances often involves interpreting electrical schematics (like blueprints) and product manuals, understanding the different components needed to make devices work, and ordering replacement parts.

You may have to take measurements and test equipment using various tools, or do some soldering, brazing, and welding if the job calls for it.

In appliance technician training, students learn about the electrical, electronic, and plumbing aspects related to the job, and get thorough training in safety and the use of power tools.


Domestic Appliance Technicians vs Appliance Repair Technicians

Although these job titles may sound very similar, domestic appliance technicians have a very different focus than appliance service technicians.

The major difference is that domestic appliance technicians work primarily with gas-fired appliances like:

  • Furnaces
  • Hot water heaters
  • Boilers
  • Some types of refrigerators

These professionals understand the fundamentals of heating, ventilation, electrical, and air handling systems. 

Although newer gas ranges and other appliances use innovative electric parts and sensors to make them much safer and more efficient than older models, they are still relatively complex to repair.

Because of the potential risks resulting from gas-fired appliances that are incorrectly installed or are malfunctioning, comprehensive safety training is especially important in this trade.

In pre-apprenticeship domestic appliance repair training, you'll learn all electrical and mechanical safety requirements as well as how to safely handle propane and natural gas.


Domestic appliance technicians work on residential and commercial gas-fired appliances. That means they must get certified by the Technical Standards and Safety Authority (TSSA).

If you choose this training path, you will learn piping, appliance venting, and relevant business practices based on the TSSA's curriculum. You'll be prepared with the necessary knowledge to pass the Gas Technician 3 certification exam at the end of the course.

Gas Technician 3 is the beginner level. It's the starting point for newcomers to the domestic appliance repair trade.
