Signs You May Need a New Limit Switch

Limit switches are safety devices inside your furnace that monitor temperature. The high-limit switch shuts off burners if the heat exchanger gets too hot. The fan limit switch controls when the blower turns on and off.

🔥Furnace Shuts Off Before Home Reaches Temperature
  • The furnace lights and runs but shuts off after a few minutes.
  • The high-limit switch may be tripping due to overheating.
  • Common causes: dirty filter restricting airflow, failed blower motor, or a faulty switch.

Always check the air filter first. A clogged filter is the #1 reason a high-limit switch trips.

💨Blower Fan Won't Turn On or Won't Turn Off
  • The furnace heats but the blower never starts to distribute warm air.
  • Or the blower runs continuously and won't shut off after the heating cycle.
  • The fan limit switch controls blower timing — when it fails, blower behavior becomes erratic.
🔄Furnace Short-Cycles Repeatedly
  • The furnace starts, runs for a few minutes, shuts off, then restarts.
  • This continuous cycling often means the limit switch is tripping on high temperature.
  • If the filter is clean and the blower is working, the limit switch itself may be faulty.
