Why Does My Furnace Shut Off Every 15 Minutes?

A furnace or heating pump that keeps clicking on and off at frequent intervals is said to be in a state of short cycling. Although this may seem normal to many homeowners, in reality, it is very far from it. Short cycling can occur due to a variety of reasons. However, in almost all instances, it requires the intervention of a professional requiring you to search for HVAC repair near me. Nonetheless, you must know the possible causes that make your furnace or heating system short cycle.

Causes That Make Your System Short Cycle

If you are asking yourself what makes your system run on such short cycles, you should consider the following cases –

• Dirty Components
  The most common reason for short cycling is that the air filter is dirty and, therefore, non-functional. This is because the heat exchanger can retain heat to such an extent that it overheats. On the bright side, you will not have to look up “HVAC repair near me” as you can replace the filter on your own. In addition to this, the furnace can have issues if the blower wheel is dirty too. This is because the wheel will not turn as easily as before.
• Corroded Flame Sensor
  The flame sensor helps the system know that a flame is present when the gas valve is opened. However, if there is a layer of dust on the sensor or if it is corrupted, it can hinder the functioning of the flame sensor. If it undergoes corrosion, you may have to search up HVAC installation near me and find a professional to install a new flame sensor.
• Clogged Flue Pipe
  The flue pipe is usually present on the roof of your home and is also known as an exhaust vent. The problem arises when leaves and other debris begin to clog it, making the flue pipe short cycle. This is because a clogged flue pipe will release the heat generated from the furnace, causing it to overheat.
• Large Furnace
  When you are looking for an HVAC installation near me, you must hire a professional. This is because installing a furnace of the wrong size can cause the system to heat a home rapidly, causing it to click on and off. The only solution to this problem is to replace the unit entirely.
• Faulty Thermostat
  Given that the thermostat controls the entire heating system, short cycling can occur if the thermostat is not working properly. This could be because the thermostat requires batteries, or it could also result from bad wiring within the thermostat. Some technicians may also state that the location of the thermostat is not ideal.

Therefore, your furnace could be short cycling for several reasons meaning that once you notice it, it may be best to bring in professionals to look into it.
