- Compatibility: Not every high limit switch is compatible with every furnace. I took the time to check the model number of my furnace and ensured that the switch I selected was designed for my specific make and model.

My Budget Considerations
When it comes to pricing, I noticed that high limit switches can vary significantly. On average, I found prices ranging from $20 to $100, depending on the brand and features. I set a budget based on my research and prioritized quality over cost. Investing a bit more in a reliable switch has saved me from future headaches.
