Do not use soap and water as some detergents can cause corrosion to the metal. It is also a good idea to check connections for leaks with an approved LP leak solution. Some models have an air shutter that can be adjusted. If it is, there is an issue with the LP supply line to the stovetop. If all these steps are verified, check another LP appliance to verify the main regulator is working properly. Often times there is an in-line shut-off valve to LP appliances that should also be checked.
If not, check to make sure the knob is actually opening on the stovetop and the valve is on at the LP container. If there is LP flow to another burner, check the supply tube to the affected burner and clean. If the burner does not light manually and has no LP flowing to the burner check another burner to verify LP flow. Visually inspect the piezo for spark attempt.

If it lights, the piezo is either defective or has a cracked ceramic case which will send the spark through the crack rather than to the burner. If the stovetop will not light with the piezo or spark assist, verify there is LP coming to the burner by trying to light it manually with a butane lighter. Periodically inspect the burner orifice to ensure nothing is spilled over and clogging which can affect performance or even start on fire. Some stovetop models have a sealed burner assembly which means the metal cover comes all the way around the burner so food can not spill over into the burner area. Stovetop MaintenanceĬompared to other appliances, there is little maintenance required with an LP stovetop/oven combination other than keeping it clean. Keep in mind the burner assembly does not have a thermocoupler so the LP will continue to flow if the knob is open and there is no flame! I have leaned against a knob in units and smelled the distinct rotten egg smell in the past! Make sure the knob is in the off and locked position when not in use. The thermostat senses temperature from the temperature bulb in the back of the oven.įor the stovetop, simply press in and turn the knob and turn the ignitor if your model has one, or manually light the burner with a long match or butane stick lighter. If the flame and the pilot light go out, the magnet drops and shut off LP to the oven. Once the thermocouple senses a flame, LP flows to the burner assembly and is lit by the pilot light. The thermostat senses temperature and some models have a temperature bulb in the back of the oven called a mini bulb. This pushes a magnet in which is a safety feature in case the flame goes out. Typically pressing the oven knob in will supply lp to the pilot assembly which must be lit manually and stay lit for at least 30 seconds until the flame reaches and heats the thermocoupler. The oven pilot must be lit before the burner assemble will light. In the case of the oven, the temperature is set at the knob and a thermostat regulates the flow of LP to the desired temperature to the burner tube. The rate of flame or temperature is regulated by the operator turning the knob to the desired height. This manifold has the control knob attached to it and in the case of the stovetop, delivers LP to the burner assembly. Most RV stovetops and ovens have an internal regulator that will reduce that down to 10” of water column to a manifold. Your main LP regulator at the LP container will reduce the pressure supplied to the rig to 11” of the water column. The first step in any appliance maintenance and troubleshooting is to understand the operation and lighting sequence.
But just like everything else in the RV industry dozens of models have come and gone over the years and today, there are dozens of brands available such as Furrion, Recpro, Suburban, and Dometic which now owns Atwood which also owns Wedgewood, and many more.Ī major shift in the industry that I have noticed in the past decade is the use of more residential appliances and furnishing especially since the slide rooms provide more space for the larger items such as residential refrigerators and electric stovetops and ovens although they take an enormous amount of electricity so the old propane models are still the majority that I have seen.įor this article, we will focus on the propane model stovetop and oven combination.

When I was traveling full time in a Winnebago motorhome training dealers across the country, the stovetops and ovens were pretty simple and there were only a couple of models, Magic Chef, and Atwood.
