How does a gas electric refrigerator work?
An RV refrigerator works by absorption and a chemical reaction between ammonia, water, and hydrogen. The ammonia is heated then goes through an evaporation and condensation process which causes the cooling effect of the fridge. The ammonia is heated either by a propane flame or electric element.
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 baffle on a Dometic refrigerator?
The baffle is inside the flue. Use an air compressor to blow air into the flue. Continue to use the air compressor to remove dust and debris that has built up around the compartment. I hope some of these basic Dometic refrigerator parts and troubleshooting tips can get you back on the road quickly. What do you think?
Why does my Dometic refrigerator not work when switched to gas?
This can be a common problem and there are many reasons why your Dometic fridge does not work when switched to the gas function. One may be that the burner is dirty and needs to be soaked in alcohol for a few hours and then dried by using compressed air.
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 to observe the arc of a Dometic fridge flame?
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.
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.
