Dometic DM2662 Refrigerator Details
The Dometic DM2662 is a two-door absorption refrigerator for recreational vehicles and mobile homes. It is meant for storing fresh and frozen food and for making ice. It has no compressor. Instead, heat from either a 120 V AC heater or an LP gas burner drives a sealed ammonia, hydrogen and water circuit. Ammonia condenses in the finned coil at the top rear, then evaporates inside the freezer section, which produces the cooling.
The automatic energy selector chooses between AC and gas. In AUTO mode, AC has priority. If shore power is lost, the control switches to LP gas, and it switches back to AC as soon as AC returns. Users can also lock the unit in GAS mode. If ignition fails, the CHECK lamp lights. To reset it, press the ON/OFF button off and then on again. The lamp stays on even if AC power becomes available again, until it is reset this way.
The DM2662 has a user-adjustable thermostat that controls both gas and electric operation. You do not need to reset it when the energy source changes. For faster ice, you can set the thermostat to its coldest position for a while. Set it back to normal once the ice has formed, or the cabinet may get too cold.
A standard 12 V DC climate control heats the metal frame between the freezer and fresh food compartments. This stops water droplets from forming in hot, humid weather. The switch is under the top decoration panel. It draws 12 V DC continuously while it is on, so turn it off when no charging source is available.
The control system has two limp modes. If the display module fails, the unit keeps running automatically at the middle temperature setting. If the temperature sensor fails, the cooling unit runs continuously on the selected energy source until the sensor is replaced and the system is reset.
Leveling is essential. If the parked vehicle is not level, liquid ammonia can collect in the evaporator tubing and block circulation. A floor that feels comfortably level to live on is enough. While the vehicle is moving, leveling does not matter.
For installation, a wood strip must run across the upper opening of the enclosure. A sealing strip on the front frame keeps the combustion system separate from the living space. Any gap of more than 1-1/2 in above the refrigerator should be blocked so heat does not get trapped there. Do not install the unit directly on carpeting.
The door hinges can be reversed with dedicated kits (black right-left 2932750-11/6, black left-right 2932750-12/4). Optional decorative door insert panels slide into grooves in the door frame. They are held in place by a decoration strip, which is either screwed or snapped in.
For maintenance, the vents and rear coils should be cleaned once or twice a year. A qualified technician should check the flue baffle, the burner and the LP gas pressure every year. The Airing Position Card (3850781-01) holds the doors ajar during storage. To defrost, use the drip tray and hot-water trays, and never use sharp tools or hot air blowers.
