SOURCE: Refrigerator for lp-gas and electri

SOLENOID VALVE Check the solenoid coil with a properly calibrated ohm meter. Remove the connector from the solenoid and measure the resistance across the terminals. The proper reading would be 49 ohms with tolerance range of ten percent. . . Next, hook up a manometer at the test port. Then check for DC volts at gas valve terminals while the unit is in trial-for-ianition. If DC volts are present and pressure is low, replace the valve. If DC volts are not present at the valve while the unit is in trial-for-ianition, verify that the wire at Plug 3, Terminal 2 on lower circuit board have DC volts v (9V or more)
IGNITER First verify proper voltage at the positive (+) and ground (-) terminals of the ignitor. The reading should be within one volt of incoming voltage at the main terminal block during trial-for-inanition Next, remove high voltage cable from igniter. The igniter should produce a sparking sound, during trial-for-inanition. If not, replace the igniter. The igniter installed on the refrigerators as original equipment is part number 2931132019 (RV Gas Model 679). This igniter is rated 50 MA. This igniter may also be used on any other model

SOURCE: refrigerator is running on LP-gas

As per the problem, its indicating towards bad thermister, it has to be replaced.----- The thermister is the part That controls the temperature.---- To test the thermistor follow this procedure :--- Disconnect the thermistor harness from the P2, 2-pin terminal on the lower circuit board. Place the thermistor in a glass of ice water (more ice than water), approximately 33° F to 35° F. Wait 8 to 10 minutes. You should get a reading of approximately 8,000 to 10,000 ohms. Always test from the wire side as shown with the meter as not to create a connection problem at the P2 connector. -------- There is a service manual available for your dometic rm-2652 refrigerator. Click the link below:-- http://www.fourwheelcampers.com/NewDometicRefrigeratorManual.pdf --------- On page number 11 is mentioned about thermistor.---Be sure that it just didn't get knocked off the fin where it attaches in the fridge. If it tests bad then it is about a $30 part depending on where you buy it and it takes about an hour to replace. Also be sure it has a good connection on the control board.
all tests are provided in service manual.-------

Tip

Freezer not working, things to check


The unit needs two fans running and good airflow, one fan outside cools the condensor coil and the other inside the unit blowing across the evaporator coil, warming it. The compressor must start up. The defrost timer stops everything and switches on a heating element to defrost the evaporator for several minutes. Please verify these conditions. The condensor coil may get clogged with dirt and lint, the evaporator may get clogged with ice build up, or the fan may quit working due to bad bearings, need for lubrication, or burn out. The defrost timer has an internal motor and contacts which may quit working, some have a way to manualy turn it to switch its mode in case it quits working.

Our refrigerator works on AC. When switched to lp gas it sometimes come on and works and then goes off. Then we can't get it to work again. Then it will work if we turn on the hot water hea


It seems like a gas pressure problem. Possible blockage or kinked pipe or faulty regulator on the gas bottle. If the fridge runs ok only when you use the gas hot water, that would change the gas flow / pressure. LP gas products are normally around 1.5 to 2.75 kpa pressure. If you have access to a manometer, the gas pressure can be checked. (NB/ You should hold a gas service licence to do this)

Hi,

From your description you have a defrost issue. I would look into why this is not defrosting in a timely manner as it is designed to. I need a model number to asset you further. Good Luck

I have a Domatic RM 2852 in my RV. The freezer works fine but the refrigerator won't cool to 40 on electricity. It cools fine on gas.


You need to unplug the heating element from the circuit board and using a digital multi meter check the ohms. You should read approximately 44 ohms +/- 10%. If it is out of range change the heating element.

2005 dometric rm 2852 wont cool


I suggest the main control board is faulty because of the spike. The voltage would have damaged some of the control circuit - even though the fuses did not blow. Sounds like a memory fault on a control chip.
