My refrigerator doesn’t need any electricity to run… or does it?
We’ve noticed that many of our customers think, because the ammonia absorption refrigerator can operate on propane instead of 120 Volts of AC power, that there isn’t any electrical requirement to make the refrigerator operate. While the complete absence of electrical power can be achieved in refrigerators made prior to 1980, the majority of units in the field today have electronic components to monitor temperature, propane presence, flame detection, and many other parameters. These electronic components will not operate without the presence of a good 12 volt / 1 Amp power supply. Usually this is achieved via the camper’s battery pack. However, when the battery disconnect is activated that power supply is no longer available. If your refrigerator “won’t turn on” your first step should be to verify the batteries are connected and have a full charge. Otherwise, you could end up paying for a technician to simply flip a switch, and that may not be as inexpensive as it sounds.
As a side note, if you are interested in achieving complete electrical isolation we can modify any refrigerator to operate without those pesky electronics. Call us for more details if you want to get “off the grid” and keep the milk cold.
