KitchenAid KHHC2090S Microwave Oven Repair

Most common issues on this model

  1. A grease-clogged cooling path that makes the oven halt on long programs
  2. A burned patch on the waveguide cover
  3. Metal showing through the cavity coating and starting to rust
  4. A keypad with faded print

A grease-laden cooling fan is where a KHHC2090S starts to go wrong, and it is a quiet process. First the fan blades pick up a film, then the airflow weakens, then the oven begins to stop during longer programs. It is also sold as the KHHC2090SSS.

We deal with it by opening the cabinet and clearing the air path from intake to vent. Then we run the oven for a full program with the cover off, watching fan speed. A fan that slows under load goes on the repair list, because it will only get worse.

Next, a look at the waveguide cover and cavity paint, and a test of the keypad. You get a written price before any part is ordered, and our work comes with a 30-day workmanship warranty.

KHHC2090SKHHC2090S questions
Why does my KHHC2090S stop during a long program but work for short ones?

Heat builds over time, so a restricted cooling path only shows up on longer runs. We clean the path and test the fan, then run a long program to confirm the fix.

Is a scorched mark on the wall inside serious?

It points to the waveguide cover, a thin sheet that can crack once it scorches and then spark. Stop using the oven, and let us replace the cover and clean the wall around it before the next use.

Can I wash the keypad with a cleaner?

Use a barely damp cloth and wipe gently. Sprays can seep under the membrane and short the pads, which is a common reason keys begin to repeat or stop answering, so avoid spraying directly on the panel.
