Built-in microwaves are worth fixing

Book microwave & range hood repair

A countertop microwave is easy to replace. An over-the-range or built-in microwave isn’t: it’s mounted to the cabinets, it doubles as the hood for your stove, and a new one has to fit the same space. That’s why most of our microwave work is on built-in units. On a wall-oven combo, the wall oven repair and the microwave can be done in one visit.

We repair over-the-range microwaves, built-in and drawer microwaves, wall-oven combos and range hoods. GE, Whirlpool, Samsung, LG, KitchenAid and Bosch are the brands we see most, and GE microwave repair leads the list.

Where built-in microwaves fail

The most common microwave failure is simple: it runs, the light is on, the plate turns, but the food stays cold. That’s usually the high-voltage diode, the magnetron or the high-voltage capacitor. These are parts that hold a dangerous charge, so this isn’t a DIY repair.

A microwave that does nothing at all often has a blown internal fuse, frequently caused by a failing door switch. Buttons that don’t respond usually point to the touch pad or the control board.

What goes wrong overhead:

  • Plate turns, light on, food still cold
  • Completely dead, no display
  • Buttons don’t respond or press themselves
  • Sparks or a buzzing noise inside
  • Hood fan won’t run or is very loud
  • Hood lights out or vent damper stuck

Sparking inside the cavity is often worn waveguide cover or damaged paint inside the oven. If you see arcing, stop using the microwave until it’s checked.

Range hood problems are usually the fan motor, a switch, or a light socket that’s been cooked by years of heat from the stove below. A loud, rattling hood fan is often a grease-loaded fan wheel that can be cleaned or replaced. If the burners below are acting up too, we can take care of the stove repair on the same visit.

Testing a microwave where it hangs

  • Brand and symptom on the phone tell us which high-voltage parts to bring.
  • Most testing happens with the unit still on the wall; it comes down only if it must.
  • The capacitor is discharged before anyone touches the high-voltage side.
  • Diodes, door switches, fuses and hood parts are stocked; you approve the price first.
  • A cup of water gets heated and the hood fan run on every speed before we leave.

The math on a built-in microwave

Countertop microwave? It’s almost always cheaper to replace it. Built-in or over-the-range? Call us first.

For over-the-range and built-in microwaves, repair usually wins. Diodes, door switches, fuses and hood fan motors are modest repairs, and replacing the unit means new mounting, fitting it to the cabinet and sometimes new trim. That math plays out constantly on microwave repair in Deerfield calls, where many units date from remodels around 2000.

A failed magnetron on an older, inexpensive over-the-range model is where we’d tell you to compare prices with a new one. The repair price comes first, and a no costs only the $75 diagnosis.

Microwave and hood questions

Hood fan or the oven itself?

Tell us whether the fan, the light or the heating quit, plus the brand; that decides which parts come with us.

(224) 778-9765
Why would a microwave run without heating?

Usually the high-voltage diode, the magnetron or the capacitor. These parts hold a dangerous charge even when unplugged, so please don’t open the microwave yourself.

Do you repair over-the-range microwaves?

Yes, that’s most of our microwave work. We test it in place and only take it down from the cabinet when we need to.

No display, no sound. Is a dead microwave worth fixing?

Often it’s a blown internal fuse caused by a failing door switch. That’s a small repair on a built-in unit.

Can you fix the fan and light on my range hood?

Yes. Fan motors, switches, light sockets and stuck vent dampers are all common hood repairs.

Can a stuck microwave drawer be fixed?

Yes, including Sharp, Bosch and GE drawers. Door and track problems are the most common issues.

Is it safe to keep using a microwave that sparks?

No. Stop using it until it’s checked. Sparking can damage the magnetron and can start a fire.
