The genuine OEM Lennox 13P94 fan and limit control governs blower activation and high-limit protection inside your Lennox furnace. It turns the circulating blower on when the heat exchanger warms up and off when it cools, while its integrated high-limit function cuts power to the burners if plenum temperatures climb too high — a key safeguard against heat exchanger damage and overheating.
When the 13P94 control fails, you may experience a blower that won't start or won't shut off, repeated high-limit trips, intermittent no-heat calls, or a furnace that cycles the burners on and off rapidly. Any of these point to a control that is out of calibration or has lost its temperature-sensing accuracy.
The OEM 13P94 delivers the precise fan-on, fan-off, and limit trip temperatures specified for Lennox furnaces, along with the correct sensing element and mounting fit. Non-OEM alternatives frequently use approximated setpoints that undermine safe, efficient heating. Fitting the factory-authorized control ensures correct blower timing, dependable safety shutoff, and continued warranty compliance.
