My fridge started smoking

If it started to smoke after a service but didnt before, check for over-filled oil.
Otherwise it is a valve seal or piston ring gap issue.

call Sears if it is under 1 year old

Had the same problem with my Whirpool range. Took off the rear panel and carefully plugged in and turned on the top oven. One of the terminals on the part labeled as 'Switch, Hi-limit' started to spark, glow and emit smoke. This part had 2 blue wires running to it. One came off of the top element in the top oven and the other fed back into the black plug on the control panel. Part in quests is held on with a single screw and has a part no. of 7403P993-60

Blue or white smoke is oil or water. Fuel smoke is black. The rough running is dirt in your carb.

Smoke white or blue? = oil overfilled possibly.

According to the Kidde website, this unit was discontinued in 2010. If the unit is more than 10 years old it must be replaced per NFPA 72 (assuming you live in the US)

lean it back and look at the belts.

if the rug has a rubber side it will melt make sure dryer is clean and no left over burnt material ..

You have a bad compressor that is the only thing that will make something smoke and not let anything stay cool

Unplug it and see if noise stops. Leave it unplugged for at least 10 min. This will tell you if it is the fridge. Be sure and check your batteries in smoke alarms if you have any. I have made several calls for noisy appliances that ended up being smoke alarm battery warnings.
