Most common issues on this model

  1. A blower that roars or rattles when the unit works as a range hood
  2. Grease screens and charcoal pads overdue for a change, so cooking smoke lingers in the room
  3. A burned part in the high-voltage chain, tested only with the circuit discharged
  4. A circuit board baked by years of rising kitchen heat and grease

Six revision codes are on record for the KBHS109SSS, from 00 up to 06, so two ovens that look identical can need different parts. That is why the first thing we do with a KBHS109S is read the whole rating plate rather than trust the front label.

When an oven like this hangs above a cooktop, the fan and filters take the abuse. Grease works into the filter and the fan motor, and the blower starts to growl or to move less air. We pull the filters, spin the fan, and look at how much grease has reached the control area.

If the oven has stopped heating, we leave the high-voltage side to our technician’s meter and not the owner’s hands. You see a written price first, and the repair carries a 30-day workmanship warranty.

KBHS109SKBHS109S questions
The fan above my KBHS109S is loud but pulls little air. Why?

Grease on the filters and blower wheel is the usual cause, and the motor strains under the load. We clean or replace the filters, inspect the wheel and test the motor bearings.

How often should the grease filter be washed?

If you cook often, once a month is a good habit. Soak the metal filter in hot, soapy water. Charcoal filters cannot be washed and need replacing, so ask us which type your unit uses.

Does the revision code matter for a control board?

Yes, boards can be specific to a build revision. Six codes are on record for the KBHS109SSS, so we read the plate on site and order the board that matches yours, which avoids a second trip with the wrong part.
