Fridge cooling shut down after noticing heavy dust on bottom coil
I have a 3year old whirlpool side byside fridge and it stop cooling in both sides. the lights are the only thing working now. There was a heavy amount of dust covering the entire lower area of coils. It has been cleaned spotlessly as of now. Could this have caused a overheating of a relay or overload switch to shut the fan and compressor down ? I did a system reboot but to no avail. there is power going into the square pin plug on the bottom right rear corner of unit but the other side of plug connection is buried inside the fridge casing. It doesnt seem to be getting any power to the fan and compressor via the red and white wires. There was no burning visually or smell.Is there any way to do a continuity check on the relay and starter peices that are attached to the side of the compressor. I shook the peice but did not hear anything and there is no signs or smell of burning. Thanks for any help you can give . bob in fla.

Re: fridge cooling shut down after noticing heavy dust on...
Hey Bob I'm gonna steer you in a differnet direction. does you refrig have electronic controls or just plain ol adjustment knobs? If just plain ol adj knobs try turning the both knobs all the way off then all the way back on to the coldest setting. then firmly tap the knobs with the handle of a screwdriver or butter knife especially the one that actually has the off postiton. this is the thermostat and i'm thinkng it has gone bad on you. you mentioned that nothing was running so if the compressor relay was bad you would still hear fans running.
if this doesnt work I would need you to give me a model number off of the unit so I could point you in the right direction and help you do some continuity tests. thanks peyton

In a way, yes. Under the refrigerator is a condenser coil. Now, yes this coil collects dust. The more dust the less air can flow over this coil and that coil has hot gas flowing through it. Now this coil has to be cooled buy a fan. So, if it has too much dust, not enough cool air can pass over the coil, coil gets hotter and hotter. That causes the gas pressure to climb and the compressor will now get too hot. This will cause it to shut off due to a safety feature built into the compressor for just that reason, (to safe the compressor, your fridge, and your home from fire). Then the fridge gets warm inside, food thaws out. Yes, dust can cause this. It is very, very, common during the heat of summer, not so noticeable in the colder months. Hope this helps FixYa up.
Many times a freezer and/or refrigeratordo not work right because of a dirty condenser coil...there are also many otherthings that can go wrong.
If you are hearing a clicking or buzzing then check out thelast two tips.
If your refrigerator is running but warm, then...
Check out these tips that I wrote about that... it is a great place to starttrouble shooting your unit...and something that you can do rather then callinga repair person to do a simple thing for you...
Have you pulled out the refrigerator and cleaned or used a vacum cleaner to get out the dirt and dust off the back of the coils, or if the coils are underneath, you need to get an inexpensive appliance brush for fridge, and clean the coils under the fridge, pull off the panel on the front bottom of the fridge, get a flash light and look to see if the coils are covered in dust....may just need to vacum and use appliance brush underneath...this should be done at least one a year, you will notice your fridge running much better and cooling back to normal.......hope this helps......
Is there a fan that blows air over the cooling coils in the freezer? Not sure if side-by-side fridges have this. This was the reason for my top freezer / bottom fridge. Air was not being blown around the freezer and down into the fridge.
pull your refrig away from the wall and check to see if your compressor is running i'm willing to bet that the start relay is bad you will here a humming and then clicking noise approx every 3-5 mins. its a very easy repair get part number 8201786 from whirlpool it has detailed instructions and should only cost you 40-60 dollars for part.
How old is it? have you ever cleaned the coils under neath where the dust gathers? I've seen people that never cleaned the coils underneath and behind the plastic grill at the bottom front of the fridge that had a warm fridge and the after they used a refrigerator brush down below were okay the next day!They had 2 inches of solid dust under there blocking the air that is supposed to be passing over the coils to cool the system!! Get out the book and read the directions how to do this procedure that I'm telling you about first before you call service! If it's not caked with dust and obscuring the site of the coils, then you need service instead! Bless You
