How do you clean the fins on an RV refrigerator?

To clean it off, you started off right by cleaning it with dish soap. Now take a lemon, cut it in half and dip it in a little salt, and gently scrub the fins. You can also use lemon juice on a rag to clean the fins. You can also use vinegar, but most people like lemons better.

Where does the igniter need to be on a Dometic fridge?

What is not discussed is the fact that the igniter should not be striking the arc within the flow of gas issuing from the burner as a rule of thumb. This figure shows the arc passing at about a 30° angle from the electrode to the burner assembly. The arc should not be directly inside the area where the gas flame is.

What kind of gas does a Dometic fridge flame use?

In this case, the gas is a mixture of air & LP gas. For the flame to ignite the ark should pass from the air into the air/fuel mixture. 2) The gas in the space between electrodes becomes ionized (positively charged by removal of one or more electrons). 3) Ionized gas is called plasma.

What do you need to know about a Dometic refrigerator?

Check the air gap between the vent grills, top, and back . A gap should be around these areas. Check the vent grills for dirt and dust. Clean them off. Don’t pack it tight. The refrigerator needs to be able to circulate air in and around the food. If it’s packed tight it won’t cool like it should.

Where is the flame alignment on a Dometic fridge?

Be sure to turn off your propane at the tank until this is resolved! Make sure the propane regulator is set at 11 inches of water column. Please use this link to read more on Manometers Referencing the photo to the left, the flame alignment should be in the center of flue.

Where is the thermistor on a Dometic refrigerator?

For the RVers that love the heat, we recommend installing some fans in the back to help with the air flow. The next thing to check is your Thermistor (thermostat/ resistor) located inside the refrigerator. It has a 4-prong connector located at your light fixture at one end and the other end connects inside the refrigerator on one of the back fins.
