Side By side. ED2FHEXMQ00. Will not Cool.

SOURCE: fridge not cooling

Most of the time on a whirlpool the problem is the relay on the compressor sometimes called the start device. I would replace that first. If you need help finding the part let me know. I will need the complete model # from the sticker inside the fridge section. You can look it up with diagrams at http://www3.sears.com/.

well you need to know when it was manufacture if it lands under the 5 years seal system warranty then it can be fix for free. on the other hand be sure that compressor is running because if it is not it could be a relay and that is a cheap fix

The easiest way to find this out , is to check the condenser. Make sure that the condenser is not clogged up with dust and that the condenser fan is working. Replace the start relay. Turn it back on. If it starts right up then it probably overheated and melted the relay due to the condenser fan not working or the condenser clogged with dust. Air circulation through the condenser and air being circulated over the compressor in how it cools itself. If the compressor will not start or if it runs for a little while and then shuts off from overheating, then you have a bad compressor.

replacing a start relay is very easy to do. usually its a swap the part wire for wire operation. in some cases you get a different looking relay but they normally have good instructions for the replacement part. if you'll post the model numebr fo your unit i can give you detailed instructions. thanks peyton

Simple Fix. That's cost around $40. You need to replace your relay/overload. Its mounted on the compressor. It should have a black box over it. Take it off then pull the part off the compressor and replace it with a new one.
