Description
The Texas Furnace (Consolidated Industries) 4035003 is an OEM replacement L190-20F high-limit switch engineered to protect your furnace from overheating conditions. Designed as a direct replacement for compatible Texas Furnace and Consolidated Industries heating systems, this limit switch delivers reliable, repeatable performance to keep equipment operating safely and efficiently.
How It Works
The L190-20F limit switch monitors heat exchanger temperatures and opens the control circuit when temperatures reach the upper limit setpoint, shutting off the burner to prevent damage. Once temperatures drop to the reset point, the switch automatically closes and restores normal furnace operation — no manual reset required under normal cycling conditions.
