KitchenAid KEMS378S Service for Door and Vent

Schedule Service(713) 903-2606
KitchenAid wall oven

Most common issues on this model

  1. Door hinge and latch wear so the door sits out of line and the interlocks no longer meet
  2. Exhaust fan that is noisy or no longer runs, where installed over a range
  3. Charcoal and grease filters that are overdue, giving weak extraction and a fan under strain
  4. High-voltage part failure best left to a technician

You can recognize the KEMS378S by the number on its plate and by a sibling labeled KEMS378SSS. This discontinued combination oven with microwave cooking is often installed over a range, where it shares duty as an exhaust hood.

The door tells us a lot. If it hangs slightly crooked, the latch no longer pulls it tight, and the switches that approve heating stop agreeing. We adjust or replace the hinge and latch parts and then run the oven to confirm it starts.

A fan that grumbles usually needs filters first, and a motor second. Written pricing is provided before we begin, and our work is covered for 30 days. We close the visit by starting the oven and confirming that the vent fan and lamp work, since owners notice those first.

KEMS378SKEMS378S questions
Why will my KEMS378S not start even though the door shuts?

The interlock switches may not be lining up because the hinges and latch are worn. We realign the door or replace the worn parts and test the switches.

Can I replace the charcoal filter on a KEMS378S myself?

Yes, filters are normally an owner task. Just make sure the oven is unplugged first, and use the filter type that matches your model number.

What do you inspect when the vent fan on a KEMS378S gets loud?

The filters first for grease, then the fan blade for debris, then the motor bearings. Most noise ends at one of the first two, and replacing the filters is quick and inexpensive for you.
