The refrigerator is suddenly reading 48 - 52 degrees. The light switch toggle is somewhat shaky - but has been working. Sometimes it has needed a jiggle to make the lights go on, but not lately. Within the past few days, I have noticed high temp. readings on digital read out for refrigerator. I have turned the unit off and turned it back on and waited a few hrs. to see if it cools back down to desired set temp of 39 - and it is not. what is wrong. This is only 8 years old cost a fortune. Thank you for any advice you can offer.
Put you own thermometer inside and see if the temperature is the same as the digital thermometer. the light switch shouldn't have anything to do with the temp. another thing to check is see if the condenser fan (condenser is the metal coil on the outside) is running, and that the coil is clean. if the coil is dirty or the fan is not running then either clean the coil or check for voltage at the fan. if you have voltage to the fan and it doesn't run then you need to replace the fan. if you don't have voltage to the fan then you may have a deeper problem. hope this helps

Put a freezer thermometer in the freezer and see if it reads +34 degrees, then put it in the refrigerator. If the freezer reading is above 0 degrees, say +34, then the freezer is too warm. If the refrigerator is reading 34 and the freezer is way cold, then the refrigerator is getting too cold. This could be either a thermostat setting too cold or the sensing isn't reading properly or a much more serious issue. Generally a refrigerator should be no warmer than +40 but not freezing either +32 degrees and a freezer should be about 0 degrees. Make sure nothing is blocking the air flow duct work or where the sensors are located.
HI PAUL.FREEZER NOT COOLING could be for many reasons.go through the basics first .1-check if your freezer is iced up 2 if yes defrost it all completely first .then turn on 3-if ok then your problem could be 4-defrost timer 5-defrost heater 6-t/stat.if not iced up then check /clean thoroughly the condenser unit 7-check con/fan 8-check condenser should be warm/hot.if cold and motor hot then it could be lack of refrigerant (internal leak?) hope this helps.ALI
The interior light in most refrigerators, and the fan in some, are controlled by a door switch. When the door is closed, the switch is depressed and the interior light goes off and the fan resumes normal operation. If the door is misaligned or the switch malfunctions, the refrigerator may become warm as a result of the non-operation of the evaporator fan and the heat generated by the interior light. Test the switch for continuity using a multimeter. Set the multimeter to the ohms setting X1. Place a probe on each terminal. The multimeter should change from a reading of infinity to zero when the probes touch the terminals. With the probes still touching the terminals depress the switch, the reading should change back to infinity. If it does not pass both of these tests, the switch should be replaced.
I usually dont go with a thermometer temp unless it is sitting in a bottle of water. Now drawer units get the air circulating from the freezer fan. Make sure that is running at a good speed. Also make sure the light is going off when the door is closed. Just close the door and pull gasket toward you and see if a light is on. If it is then make sure the switch is working.If not check the freezer for heavy frost.If yes then you have a defrost problem. If no then you need a tech to check the sealed system.
