Microwave repair: a guide for pros

What customers ask, how to win the job, and what to put on your profile.

Offering microwave repair

You repair microwaves, including the high-voltage parts that hold a dangerous charge after the unit is unplugged. You win this work by following safe discharge and test procedures, and by proving the door interlocks work before you leave.

What customers ask

  • Why does my microwave spark inside?
  • Why is the food cold even though the microwave runs?
  • Is it worth repairing an older microwave?
  • Why won't the door latch?
  • Is it safe to keep using it until you come?

How to win the job

  • On the first call, ask whether the unit heats at all, whether it sparks, and whether the door latches, then give a likely cause and a safety warning if needed.
  • Carry fuses, door switches, latch assemblies and common high-voltage parts for the brands you service, and only work on them with proper training and safe discharge.
  • Inspect the waveguide cover and the cavity for burn marks before you replace any high-voltage part.
  • Test the door interlocks and run a heat test with a water load before you leave.
  • In the quote, name each part, the test that confirmed it and the warranty term.
  • Tell the customer plainly when a unit is not worth repairing, and why.

What to put on your profile

  • Photos of replaced door switches, fuses and waveguide covers
  • The microwave brands and models you service, listed by name
  • Whether you service over-the-range and built-in units

Follow-up that helps the customer

  • Suggest keeping the waveguide cover clean and the cavity free of grease
  • Recommend replacing a damaged door seal before it lets heat or steam escape
  • Remind the customer never to run the microwave with the door open or the latch broken

Licenses and permits

Microwave repair is often not licensed as a trade, but work on high-voltage parts should be done only by trained technicians, and electrical connections can need a licensed electrician. Check state and local rules with your licensing agency before taking this work.

Questions

Do I need special training to repair a microwave?

Yes for the high-voltage parts. Those components can hold a dangerous charge after unplugging, so train properly and follow safe discharge procedures before you touch them.
