Microwave problems are more than an inconvenience. No-heat issues, sparking, or a door that will not latch can point to serious electrical or safety faults. ARS Repair and Installation Services Inc. Toronto repairs all major microwave brands used in homes, condos, rental units, staff kitchens, and small commercial spaces.
We service countertop units, built-in models, and over-the-range microwaves. If your microwave is not heating, shutting off mid-cycle, making loud noises, or showing error codes, our technicians find the cause and restore safe, reliable operation.
Why Timely Microwave Repair Matters
Microwaves rely on high-voltage parts, safety switches, and control boards that must work together. When one part starts to fail, stress is placed on the rest of the system. Waiting too long can turn a simple repair into a full component failure.
A properly repaired microwave will:
- Heat food evenly without cold spots
- Run without sparks, burning smells, or arcing
- Keep the door and safety switches working correctly
- Operate without shutting down mid-cycle
- Work quietly at normal fan and motor levels
Why Microwaves Malfunction
Over time, heat, moisture, and repeated door use wear down internal components. Electrical parts can weaken, safety switches can go out of alignment, and moving parts can fail.
Common causes include:
- Weak or failed magnetron
- Faulty high-voltage diode, capacitor, or transformer
- Broken or misaligned door switches and latches
- Turntable motor or drive coupler wear
- Control panel, keypad, or display failures
- Damaged waveguide cover or interior arcing
- Cooling or airflow problems inside the cabinet
We test each system carefully and explain what failed, why it happened, and the best repair option before any work begins.
Common Microwave Issues We Fix
- Microwave runs but does not heat
- Sparking or arcing inside the cavity
- Door will not close or unit will not start
- Turntable not rotating or turning unevenly
- Buttons not responding or display not working
- Microwave shuts off during or shortly after start
- Loud humming, buzzing, or grinding noises
- Burning smells, hot cabinet, or tripped breaker
- Error codes or intermittent power issues
If you notice any of these symptoms, stop using the microwave and schedule service to prevent further damage.

Amazing service… This Samsung fridge has had an issue with the ice maker since I bought it. After multiple complaints to Samsung and multiple companies coming to my house wasting my time and just thawing it out and saying it's a design flaw, I almost gave up. Then I gave it one more chance, and ARS was the company that came and finally solved my problem. The technician was super nice, and you could tell he knew what he was doing. The ice maker has never worked better—no more freezing!!!!!! Thanks, ARS; you did an awesome job.
Thank you for great service. The issue was with the Samsung ice maker; then more issues were added, and everything was broken. Basically, the fridge and freezer warmed up. So after a few times fixing and figuring out what's wrong with it, everything works perfectly now. Thanks to the knowledgeable technician.
The ARS technician Qaiser was friendly and very knowledgeable. He came to assess my washing machine. He asked a lot of questions to help him understand the issue. He stayed for a full spin cycle to make sure I knew what the problem was, leaving me feeling very confident that it was fixed. And he shared good advice too. I will call ARS again and ask for Qaiser in the future and have already recommended him to family.
Your technician, Andre, came on time to fix the washing machine that did not spin properly. He was very efficient and knowledgeable. I also liked his attitude; he was very thorough, explained where the problem was, and proceeded to fix it. I was very satisfied with the service; the technician was indeed well-trained and competent.
We had a simple repair, and there were no issues. The repairman arrived when promised, was polite, and did the job as expected. I would use ARS again.
What great customer service! We had an issue with ice forming in our Samsung fridge since the water was not draining out as it should. We reached out to Samsung Canada to resolve the issue. Samsung Canada referred us to ARS, and we are so glad they did. They promptly scheduled an appointment, and Andre, the technician, did a great job. He arrived on time and finished the work promptly. He also shared some tips to keep the fridge working efficiently. The issue was resolved, and the fridge is working properly. We're very happy and thankful for the great service.
We were all set to purchase another stove when we remembered ARS repair. They arrived when expected and resolved our problem, saving us hundreds of dollars. We'd highly recommend them for any appliance repair.
I had a problem with the fridge. The ARS repairmen arrived on time and did the job very professionally. Highly recommended.
Our LG fridge stopped cooling. LG referred us to ARS to repair our fridge. They were very helpful and booked our service to the earliest date possible. The technician was very friendly and professional. Within hours, the compressor was changed, the fridge was fixed, and it was working like new. Great job, ARS!
The tech that arrived to service my fridge was friendly and professional and efficiently diagnosed the issue. The best part was they had the part on hand and were able to complete the repair in one visit. The tracking system to see where in line you are for that day's service calls is a very helpful feature, which allowed me to minimize the time spent waiting for the technician to arrive. Overall, I would highly recommend ARS.
