This is probably a 10-year-old KitchenAid Superba but looks fairly new.
Yesterday I removed the bottom front grille and cleaned out tons of
dirt. (The previous owner probably never did it.) Now I notice: (1)
The door edge no longer feels hot. (2) The fridge seems to almost
constantly run. It's still cold inside, though. (3) The warm air at
where the bottom grille is doesn't feel as warm as before.

Did I accidentally turn off the door edge heater (if any)? Why would
that keep the fridge running non-stop? Thanks.

Yong, Since you've removed the debris, the heat and air transfer are proper, and the condenser assembly is working properly. The mullion or post condenser loop is working proper and the "door heater" should be warm but not hot.
Now that it's working proper, it may seem to run more, during the day/ evening, and is probably cycling off at night, when you're asleep, and don't know it.

Thanks and Good Luck,

Hi.

That was a very good thing -cleaning the condenser.

The refrigerator isn't running hot anymore.

Adjust the temperature setting to warmer position and allow

24 hours to settle.

Thank you. Post the results.

Simon.

Thank you both. But I watched a few days and I really think the fridge runs longer than before. Somebody told me it could be the defrost timer. Maybe I accidentally put some dirt in it. But I carefully checked what's behind the front grille where I took lots of dirt out. There's really nothing except black metal coils. The model of this fridge is KSCS25INWH00. I searched on Google but can't find the defrost timer.

Yong,
First off, you don't have a defrost timer. You have an electronic control board, that determines what the refrigerator needs to do, based on inputs from the sensors, and determines when the machine needs to defrost. It's located in the refrigerator compartment, behind the digital display, it's not likely you got dirt in it.

You may want to review the User's Manual, reset the controls and check the food product temperature in 24 hours. Room temperature can also affect the compressor operation, The hotter the room, the more the compressor will run. Make sure the air flow is not disrupted or re directed by large articles blocking the air tunnels, or articles hanging over the shelves or against the walls.

Good Luck and Thanks,
