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 to do if your Dometic Fridge is not working?
Once the burner is removed you can see a daisy shaped nozzle down the cylinder. Blow any dust, soot or rust from the nozzle. If you need to replace the jet then the burner needs to be removed from the gas pipe. Carefully unscrew the gas pipe from the burner.
How many electrodes are in a Dometic fridge burner?
Referencing the photo to the left, a gas igniter arc is shown, the ark is jumping from an electrode to the LP Gas burner. Please note, your burner will have only one electrode, this photo shows two electrodes, we used two electrodes for experimentation and development of the Fridge Defend by ARP.
How do you remove flue from Dometic fridge burner?
Loosen the screw closest to the heater can body and remove the top section of the flue. You should now see a small piece of wire hooked over the top of the remaining section of flue – this holds the baffle in place. Using the wire to lift the baffle out of the flue.

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.
How do you clean out a Dometic fridge burner?
If you want to clean the burner out you will need to disconnect the gas pipe from it and undo the clamp bolt that holds the ignitor electrode and thermocouple in place. Looking in through the top vent you can see the top of the flue, with this access and the burner removed from the bottom of it you can now sweep it out.
How does a Dometic fridge Flame get started?
The air around the ark and gas mixture is ionized (more on this below), that ignition of the flame is a 3 step process, plus a 4th step that kills your controllers by introduction of electrical noise if igniter is not adjusted properly: 1) Arc passes through air and LP gas mixture.
How to adjust the electrode on a Dometic fridge?
Trial and error may be the best method to adjust the electrode in some cases. Just observe the location of the arc when the LP gas has been turned off, then turn on the gas and make sure that the arc passes through the open air into the location where the flame is observed.
How to operate a Dometic fridge on a gas caravan?
Dometic – u have to turn to gas symbol- press in the temp button and hold whilst u press the ignite button. is it telling you it needs a service dont matter if its not been used the flu may be blooked (cobbwebs etc) Quote “Firing up a gas fridge can take some time.
Is there a reset button on the Dometic refrigerator?
Finding Dometic RV Refrigerator Reset Button & Using It! Finding Dometic RV Refrigerator Reset Button & Using It! Proud owners of Dometic RV refrigerator are almost always stress- free with their camping trips. But sometimes the situation does not go according to plans, and that’s pretty normal.
Why does the Dometic RV refrigerator check light go on?
The dometic RV refrigerator check light is designed to goes on if there is something wrong with the gas system. To ensure that the fridge could achieve peak performance, you have to find out the reason behind the check light activation before hitting the road.
How does a Dometic refrigerator work with gas?
Dometic refrigerators use gas absorption cooling units. Heat boils an ammonia and water mixture, and as the ammonia vapor rises, it moves along a coil system. This Ammonia vapor condenses to a liquid, and then finds its way to the evaporator.
How to troubleshoot a Dometic RV refrigerator that is not working?
Certified Mobile RV Technician, Darren Koepp, troubleshoots a Dometic RV refrigerator that is not working on propane. In this instance, the electrode wire was damaged and shorting out and therefore the burner was unable to ignite.
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.
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.
