Frequently Asked Questions

Dometic New Generation (RM3762 and RM3962) Refrigerators

  1. Once I’ve turned the unit on, what’s the next step to get it going?

    First, make sure to set the Control Panel to the Auto Mode. Press this button to turn the AUTO mode ON or OFF: Button In = Auto Mode (Attempts Electric Mode First) Button Out = Auto OFF (Attempts LP Gas Mode Only

  2. Where do I find the temperature settings?

    TEMP. SET button - The thermostat has five settings where “1” indicates the warmest and “5” the coldest temperature setting. Press this button once to display the current setting. Continue to press repeatedly until the desired setting, e.g. “3”, is shown in the LED display. This value is shown for about 5 seconds and then the fresh food compartment temperature is displayed once again.

  3. What does it mean when the AUTO indication dot on the Control Panel is lit and the LP indication dot flashes slowly?

    That indicates that the Temporary gas lockout function is on. Only in AUTO mode. It delays LP gas operation by 15 minutes when ignition switch is turned OFF. This is for stopping at a refueling station.

  4. What does it mean when the Digital Display message for the fresh food storage compartment temperature reads “60” or “LP”?

    If the fresh food storage compartment temperature indicator reads “60” it means that the fresh food compartment temperature is above measurement range. If “LP” is flashing (the message alternates between “LP” and the fresh food compartment temperature), the LP gas operation is locked out, so the LP gas supply should be checked.

  5. What do I do if my unit has been turned off for a while, or I change the LP gas tank and it won’t fire back up?

    Most likely it means that you need to purge air from your gas supply lines. To purge air from the lines, turn the refrigerator off and on by pressing the ON/OFF button. If the flame is not lit within 45 seconds, turn the refrigerator off and back on again. This procedure can be repeated 3 to 4 times. If repeated attempts fail to start the LP gas operation, check to make sure that the LP gas supply tanks are not empty and that all manual shut-off valves in the lines are open. If the problem persists, turn the refrigerator off and take it to a Service Center.

  6. What can I do to reduce frost build-up?

    The easiest way to prevent frost buildup, which can reduce efficiency, is to wipe excess moisture off items being placed in the compartment.

  7. Is there a quicker way to make ice than just waiting until it happens?

    Yes! For faster freezing, place trays in direct contact with the bottom of the freezer compartment. Ice will be made more rapidly if the thermostat is set at its highest position, but be sure to move the thermostat back to normal setting when the ice is formed; the refrigerator might otherwise become too cold.

  8. Sometimes when I open the refrigerator door a strong odor comes out. What could be causing it?

    The food storage compartment is completely closed and unventilated, which is necessary to maintain the required low temperature for food storage. Consequently, foods having a strong odor or those that absorb odors easily should be covered.

  9. My refrigerator doesn’t seem to be cooling as it should. What should I look for?

    There are a number of items to investigate if the unit is not cooling as it should. 1. Check the thermostat and adjust if necessary. 2. Check to see if there is a power failure. 3. Is the refrigerator level? (Due to the nature of its operation, it is important to keep an absorption refrigerator level.) 4. Does the door close properly? Check the door gasket to make sure it fully seals when closed. 5. Is there heavy frost build-up on evaporator fins? To prevent frost buildup, do not leave the unit’s door open longer than necessary. 6. Are there too many items jammed inside the unit? The unit will have to work harder if refrigerator is stuffed, and results in higher cabinet temperatures. Arrange food in the unit to allow for free air circulation.

  10. What do the Error Codes mean?

    E0 = No communication between display and power module.
    E1 = Disconnected LP gas valve or hardware fault in the LP gas operation system. The refrigerator may still be operational on 120 VAC.
    E2 = A failure of the temperature sensor device or associated electronic circuitry has occurred. Make sure the sensor wire is connected.
    E3 = The cooling unit has malfunctioned. Contact a Service Center.
    E4 = DC voltage is out of range (exceeds or drops below the limit values, approximately 8-18 VDC).
