Dometic rm7732 service manual

The Fridge Defend can be mounted on the Dometic control box. Please use this image along with the following sections for installation of the ARP boiler temperature sensor. Once the boiler housing is opened, remove the insulation just above the heaters. There are two tubes inside the boiler housing, one is the flue tube, in this photo the flue tube is behind the black arrow.

The other tube is the boiler tube. The boiler tube is easy to identify because the electric heater mounts are welded to the boiler tube. Please note the yellow arrow, there are a number of features as follows: There are crimps in the boiler tube, the ARP boiler sensor is clipped to one of the bulges created by the crimps. Also, the sensor tip is in contact with the boiler tube. Lastly, insulation is placed between the ARP sensor and the flue tube, the black arrow points at the added insulation.

Please note that all of the following specifications are believed to be accurate. On RM Product No. The refrigerator will not switch to another mode of operation until all ACpower is lost.

The heating element is designed to deliver a predetermined amount of heat to the cooling unit. To check a heating element, remove the heater leads from the printed circuit board and measure for proper resistance across the two leads with a properly calibrated ohm meter.

This check is to be done with the heating element at room temperature. The proper ohms for each of the two RM and RM heating elements is 69, with a tolerance of ten percent. If the resistance is outside the tolerance range, replace the heating element. For the refrigerator to operate on any mode, DC voltage must be supplied to the terminals at the rear of the refrigerator and must be connected directly to the battery of the RV.

The operational range is Connecting the refrigerator to an unregulated converter can result in improper operation of the refrigerator. Do not use the body or chassis of the RV as a substitute for either of the two conductors.

Proper polarity is crucial for the operation of the refrigerator. Check for proper voltage at the positive and negative. If power is outside the operational range, correct the power supply problem. The power supply to the refrigerator must be fused. Maximum fuse size: 5 amps. With the refrigerator operating on AC or gas mode, if voltage to the refrigerator slowly drops to or below 9. Low DC volts below 9. For the refrigerator to operate on any mode, DC voltage must be supplied to the terminals at the rear of the refrigerator.

The operational range of the unit is a minimum of 9. The unit will automatically shut down until voltage has decreased to 18V DC. The refrigerator requires at least 9. Proper polarity is crucial for refrigerator operation. Check for proper DC voltage at the positive and negative terminals at the back of the unit. If the voltage is outside the operational range, correct the power supply problem. The thermostat operates on DC volts and regulates the inside refrigerator temperature on all modes, by making and breaking the circuit to the printed circuit board.

The internal mechanism breaks contact continuity when adequate cabinet temperature has been reached. Check the thermostat for continuity. This check should be made at room temperature with the thermostat turned all the way to MAX. Another check would be to use a jumper wire with insulated clips and bypass the thermostat. NOTE: Use care when doing this test. Do not short to thermostat casing. Also remove jumper after testing is completed.

A defective thermostat would cause insufficient cooling, no cooling or freezing on all modes. Welcome to ManualMachine. We have sent a verification link to to complete your registration.
