The application for this design will be a central air heating system (furnace) for residential use. The furnace is controlled by a thermostat as well as a fan and limit control installed in the air heating chamber leading to the warm air duct distribution system...
A control board is a circuit board that consists of several resistors and relays. These components control the speed, temperature, and other functions of your furnace’s fan and burners. In most cases, you can find this control board located inside the control panel of your furnace. The contr...
Little project that replaces part of the fan limit switch inside my furnace. This is a time-based solution and does not replace the temperature limit part of the original switch. When powered up a relay gets energized which bypasses the fan (not limit) switch. The datasheet/code is pretty...
An electric control for gas furnaces which controls a two speed main blower fan and an induction draft fan based on inputs from a room thermostat, a high limit and an ignition control including a gas valve. The control has a circuit board having a power supply for providing 24 volts DC ...

Budget-friendly and efficient, our gas furnace delivers efficient warmth with reliable single-stage operation and an 18-speed blower. It features a high temperature limit control and is ENERGY STAR qualified. Efficiency RatingUp to 97.0% AFUE ...
then either the fan control, limit switch or lower limit switch will tell the blower to stop once the temperature inside the heat exchanger has cooled to a ‘pre-set’ temperature. Also remember that the burner ignites (comes ON) before the blower starts and extinguishes (goes OFF) before ...
The blower fan moves heat into the ducts. Air flow is monitored by limit switches. The thermostat signals that it is satisfied and the control board shuts off the gas. Recommended Furnaces 97%+ AFUE Trane XC95m Converts up to 97% of every dollar spent on gas into heated air for your...
