Problems solved by technology

Problems with spark-type igniters, however, include among other things the electronic and physical noise produced by the spark.
Known ignition modules for gas-fired burners, however, are susceptible to malfunctions in use.
In addition, the modules are often sensitive to voltage on the neutral conductor which desensitizes the flame detection circuit and can lead to continuously generated sparks despite the presence of a flame on a burner.
If the electrical junction box is not properly wired, the i...

Embodiment Construction

[0038]Referring now to the various figures of the drawing wherein like reference characters refer to like parts, there is shown in FIG. 1 an exemplary conventional free standing gas range 10 that includes an outer body or cabinet 12 that incorporates a generally rectangular cooktop 14. An oven, not shown, is positioned below cooktop 14 and has a front-opening access door 16. A range backsplash 18 extends upward of a rear edge 20 of cooktop 14 and contains various control selectors (not shown) for selecting operative features of the heating elements for cooktop 14 and the oven.

[0039]In the exemplary free standing gas range 10, the cooktop 14 includes four gas fueled burners 22 which are positioned in spaced apart pairs positioned adjacent each side of the cooktop. Typically, each pair of burners 22 is surrounded by a recessed area 24 of the cooktop 14. The recessed areas 24 are positioned below an upper surface 24 of the cooktop 14 and typically serve to catch any spills from cooking...

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 60 / 225,891 filed Jul. 15, 2009, the teachings of which are incorporated herein by reference.FIELD OF INVENTION[0002]The present invention relates to control systems for fuel burner igniters and more particularly to control systems for electrical resistance-type igniters for fuel burners and methods for controlling the voltage thereto.BACKGROUND OF THE INVENTION[0003]There are a number of appliances such as cooking ranges and clothes dryers and heating apparatuses such as boilers and furnaces in which a combustible material, such as a combustible hydrocarbon (e.g., propane, natural gas, oil) is mixed with air (i.e., oxygen) and continuously combusted within the appliance or heating apparatus so as to provide a continuous source of heat energy. This continuous source of heat energy is used for example to cook food, heat water to supply a source of running hot water...
