Tempstar prints the furnace model number on the equipment label, usually inside the front access panel or on the blower compartment door. Turn off power to the furnace, remove the appropriate panel, and look for a label listing the model and serial numbers. Copy the model number exactly, including letters, numbers, and any hyphens. Enter it in the search bar to filter this page to the parts that fit your model. Because the model number identifies the entire furnace, it narrows the full catalog to compatible parts across every category, not just limit switches. That means fewer wrong orders and a faster repair.

Repair Clinic's online repair library helps Tempstar Furnace owners and technicians work through the diagnosis and installation. Troubleshooting videos, symptom articles, and part testing walkthroughs help you determine which component has failed. Once you know what to replace, use the model number lookup to confirm the exact OEM part, then follow the matching installation video from start to finish.
