LP Gas Igniter Troubleshooting

RV Fridge Flame Adjustment of Arc Gap for Easy Ignition

The following discussion is for individuals that are having problems with ignition of the gas flame. In addition, an improperly installed igniter can result in electrical noise that can disturb other electrical equipment in your RV. If you are not sure about if your igniter is functioning properly, take your fridge to a RV refrigerator repair shop to have it check up. RV fridge flame adjustment is critical for proper function of you fridge.

The use of LP Gas as a heating source for your Norcold refrigerator allows you to use it pretty much anywhere at anytime, this is commonly called boondocking.

The proper LP pressure to your various devices should be checked and adjusted by a qualified service technician in a RV refrigerator repair facility that understands the importance of maintaining proper pressures and how to accurately measure the pressure.

If you have an issue with either the igniter not properly lighting your propane, or the flame isn't the proper blue color - please seek a qualified propane repair technician immediately! 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 following link to read more on manometers: LP Gas Pressure - Manometer.

Norcold Ark Gap Adjustment

Referencing the figure to the left, this is a Norcold gas burner assembly. The two red lines represent the burner chimney (flue). Most manufactures have a specification for distance 'd', which is the distance from the igniter to the gas burner assembly. Trial and error may be the best method to adjust the electrode in some cases, we have found that a wider gap is better, 3/16 to 1/4 inch. 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, if possable. Put the cover on the burner, it should take one strike of the arc to ignite the gas flame when the gas pressure is correct, the burner assembly is aligned with the jet properly, & the electrode is adjusted correct.

Flame Adjustment

Referencing the photo to the left, the flame alignment should be in the center of flue.

Clean the flue before use after long storage or non-use of your refrigerator. An important part of RV refrigerator repair is to make sure that bugs have not made nests inside your flue. These nests can be very hard to remove.

These little tips of RV refrigerator repair maintenance will help keep your refrigerator very efficient and safe - and you - a happy RV'er! Refrigerator Troubleshooting and Maintenance are critical for a long life for your fridge.

The Science behind LP Gas Ignition & Electrical Noise

What Happens when the LP Gas is Ignited?

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.

2) Arc ionizes the moisture in the air.

3) Ionized moisture in the air decomposes the LP gas to where it will not ignite.

44) An electrical potential creates an RF field by the frequency of the arc and the inrush of ions from the free air to balance the electrical potential created by the process.

Too summarize the flame ignition process, the following steps occur:

1) An arc passing from one electrically charged electrode to another is due to the gas becoming a conductor of electricity. 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. Plasma is the 4th state of matter, where the states of matter are as follows: solid, liquid, gas, and then plasma.

4) Research by S. A. Arrhenius showed that molecules in solutions would dissociate and migrate (travel) to the electrodes of opposite polarity. For more information on this subject visit: Global Plasma Solutions

5) The molecules that become charged by the electrical arc will encounter ions of an opposite polarity, or a grounded surface, at which point they lose their charge. Thus return to their original molecular state which is without a positive or negative charge.

The following discussion is for individuals that are having problems with ignition of the gas flame.

An improperly installed igniter can result in electrical noise that can disturb other electrical equipment in your RV. If you are not sure about if your igniter is functioning properly, take your fridge to a RV refrigerator repair shop to have it check up.
