A two-stage gas furnace control system automatically shifts into a high fire only mode if, in two consecutive low fire heating cycles a limit switch is tripped to indicate that a gas valve is stuck in a high fire condition. In this way, continued operation is allowed to proceed in a ...
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...

Combination Fan & Limit Control: This control turns the furnace blower on and off at the proper times. Details of just how a warm air heating system works and how its controls function as well as how these components are inspected, tested, set, or re-set are provided at FURNACE OPERATION...
exchanger cools but if the clogged air filter is not corrected then the problem will recur and the furnace will not provide the proper amount of heat. Sometimes the limit switch will get stuck in the open position. Furthermore, this results in a service call from a contractor to replace ...
It’s the job of the high-level/high-limit switch to shut down the furnace if the temperature in the combustion chamber reaches a certain temperature. This excess heat can be caused by a leak in one of the combustion chamber tubes or by the improper exhausting of the hot air (which ...
of the equipment, and guide rails are installed on both sides of the furnace door to ensure that the furnace door is opened and closed smoothly without shaking; Open immediately, reach the designated position, control the motor to stop by the limit switch, and close the furnace door in ...
5-2. In the case that you find temperature controller is not stable during running, you shall use "Auto-Tune" function to achieve the best setting result, please refer to the manual for the details of auto-tune. 5-3. Never cool down too fast at high temperature to protect the tube ...
It can realize automatic program operation and has manual operation function. This system can realize: *Industrial computer remote monitoring; *Manual / automatic control of production process; *Programmable temperature control; *Programmable control of mechanical action; *Chart record of temperature; ...
For safety, a thermo-sensitive limit switch 35 may be provided in the circuit and constructed to open if the temperature in the furnace becomes too high. Switch 35 is a normally closed switch but opens and interrupts power to the entire system when an excessive temperature is reached in the...
