How To Troubleshoot a Refrigerator Thermostat

It is certainly a downer when you excitedly open your refrigerator and find that everything has become almost frozen. Of course, this is a good thing for water and other beverages that you want to be as cold as possible. But it would really be unpleasant if it was just the chilled milk that you were looking forward to drinking. If this is the case with your refrigerator, something must be wrong with its thermostat. There is no need for immediate worry, though. Before thinking of buying a new refrigerator and replacing your current one, you can try doing some simple troubleshooting guidelines first. They may be all you need to fix the problem. Doing these may save you a good amount of money. Just read on and you may find your beverages just the way they should be after a few hours.

  • Simply check the thermostat. Sometimes, there is absolutely nothing wrong with your refrigerator. If you look at the thermostat, you may find that it is not set at the right temperature. Family members may have gotten something and the thermostat may have accidentally moved. If so, all you have to do is to adjust it to the right one. If the temperature is just right but the food items don’t seem to agree with it, then you may have to do troubleshooting on the thermostat.
  • Unplug refrigerator. Make sure your refrigerator is unplugged. Then, locate its control panel where its thermostat is. It is best that you take out all the items so that you can reach on it properly.
  • Remove the controls’ covers. The controls have covers that are sometimes screwed or clipped. There are also refrigerator models that have dials to be removed before the cover can be taken off.
  • Turn dial to coldest setting. Remove two leads or wires on your refrigerator’s thermostat. It may be convenient for you to note down which of the leads goes wherever.
  • Begin adjusting the settings. Set to RX1its volt-ohm multimeter and probe its terminals. To “probe” means to touch the probes of a multimeter to a terminal on your panels thermostat then the remaining probe to its remaining terminal. You should see that the reading is on zero. If not, you must begin removing the thermostat. Take it to your nearest appliance store and have it replaced.
  • Remove thermostat. If you are getting the zero reading, start removing the thermostat entirely. Bring the setting of the dial to its warmest temperature. After doing so, place your thermostat inside a freezer for about 30 minutes. After 30 minutes, re-probe its terminals then look for the reading indicating infinity, if you see it, it would mean that your thermostat is just fine. All you need to do is to reinstall it. You can now plug your refrigerator back. Something else must be wrong so look for other causes for the freezing of your items. However, if you do not see your infinity reading, it means that your thermostat must be replaced.

If you are still unsure of what is wrong with your refrigerator, you may check on other references to see what is wrong. If your uncertainty continues, it is best to have a technician look at it just to be sure.
