Navigating the intricacies of appliance repair often involves understanding complex electrical components. The Robertshaw Infinite Switch Wiring Diagram is a crucial piece of information for anyone dealing with heating or cooking appliances that utilize this type of control. This diagram serves as a roadmap, detailing how the switch connects to the rest of the appliance's electrical system, ensuring proper function and safety.
What is a Robertshaw Infinite Switch Wiring Diagram?
A Robertshaw Infinite Switch Wiring Diagram is a schematic illustration that shows the electrical connections for a Robertshaw infinite switch. These switches are commonly found in electric stoves, ovens, and some other heating appliances. They are called "infinite" because they allow for a variable range of heat output, unlike simple on/off switches. The diagram details each terminal on the switch and how it connects to the heating element, the power source, and potentially other components like indicator lights or thermostats. Understanding this diagram is vital for troubleshooting, repairing, or even replacing the infinite switch.
The diagram typically uses standardized symbols to represent different electrical components and wires. Key elements you'll often find depicted include:
- Power input terminals
- Terminals connecting to the heating element
- Terminals for indicator lights
- Ground connections
For example, a common configuration might involve a line (power) terminal, a load terminal that goes to the heating element, and a separate terminal for an indicator light. The position of the control knob on the infinite switch determines which internal contacts are made, thus regulating the flow of electricity to the heating element and controlling the heat level.
There are various types of Robertshaw infinite switches, and their wiring can differ. A basic example of how a simple single-pole, single-throw (SPST) infinite switch might function is as follows:
- When the knob is turned to the lowest setting, a small amount of current flows to the heating element, providing low heat.
- As the knob is rotated further, more contacts are made, allowing more current to flow and thus increasing the heat output.
- At the highest setting, the maximum current flows, resulting in the highest heat.
More complex switches might have multiple circuits for different heating elements or combined functions. Consulting the specific Robertshaw Infinite Switch Wiring Diagram for your appliance model is always the best approach. A table illustrating typical terminal functions might look like this:
| Terminal Designation | Function |
|---|---|
| L1 | Line (Power Input) |
| L2 | Line (Power Input) |
| H1 | Heating Element Connection |
| H2 | Heating Element Connection |
| IND | Indicator Light Connection |
