An External Digital Refrigerator Thermometer Can Warn You of Malfunction
The temperature inside your RV refrigerator/freezer can fluctuate for many reasons, such as adding food after grocery shopping, a hot sun on the outside wall where your fridge is installed, unit malfunction, or interruption of electricity or propane. This could cause your food to defrost then refreeze, potentially allowing harmful microorganisms to get a toehold and spoiling or turning your food rancid without you knowing it. A digital refrigerator thermometer with remote temperature sensor probes — available from RV supply stores — can warn you of temperature extremes. This will enable you to take corrective measures before your food spoils or, even worse, you are stricken with food poisoning.
