Your furnace should turn on when the temperature in your home is lower than what you have set and turn back off again when the temperature reaches it. In some cases, a furnace will turn on and off very quickly, which is called short cycling. Read further to learn why the heating system in your Henderson, NV, home might short cycle.
Faulty Flame Sensor
Your furnace’s flame sensor creates a tiny electric current that passes through the sensor to the board. That tiny current proves to the furnace that there’s a flame. If something’s wrong with the flame sensor, it won’t send the current, which will cause the furnace to shut off as a safety precaution.
Bad Igniter
Your furnace’s igniter creates a spark that lights the gas. Sometimes, it’s made of ceramic and metal wires, and other times, it’s different. In all cases, if the igniter is faulty, it won’t light the gas, which will result in the same kind of safety shutdown that happens with a faulty flame sensor.
Problems With the Gas Supply
Quite a few things could impede the flow of gas into the furnace. The most common is a malfunctioning gas valve. One of our service technicians can repair it.
Clogged Air Filter
While having a dirty air filter sometimes causes your furnace to overheat, it can also create short cycling because of the poor airflow. The backup of warm air will increase the pressure inside your furnace, and that will cause a safety shutoff.
Malfunctioning Thermostat
If your thermostat is having problems, it could be sending unusual information to your furnace. These unusual messages could tell the furnace to shut off and on quite quickly, causing the short cycling. You can rely on one of our professional service technicians to let you know if this is the case.
