A List of Furnace Safety Features and Their Common Malfunctions

Most furnaces have built-in safety features, to protect your home and ensure that your heat arrives without difficulty. If you’re concerned about your furnace, Clute TX has plenty of companies able to discuss the various safety features with you. When those features malfunction, they usually shut the furnace off completely. This is good because it means your safety won’t be endangered by the issue. On the other hand, without a furnace, your winter nights are apt to get quite chilly indeed. You need to get the faulty part replaced and you furnace back up to speed quickly, which usually means identifying the problem fast. Here’s a quick list of furnace safety features and their malfunctions, to help you point the repairman in the right direction.

  • Venting. The venting pipe removes carbon monoxide and similar toxic chemicals from the furnace system. If it becomes clogged or block, toxic gases can escape into your home. For modern furnaces, this will result in an automatic shutdown. If you have an older furnace, you should install a carbon monoxide detector nearby to help detect this kind of problem.
  • Thermocouple. The thermocouple regulates the flow of gas into the furnace, and opens when it detects heat from the pilot light or ignition system. If the pilot light has gone out or the ignition system is malfunctioning, the thermocouple won’t operate. Similarly a problem with the thermocouple itself should result in the gas being completely shut off. You’ll need to replace the faulty component before the furnace will run again.
  • Circuit breaker. This is a household safety feature rather than one specific to the furnace, but the principles are the same. It will cut power to the furnace if there is danger of an overload, and if the power keeps going off then some electrical component within the furnace will probably need to be fixed.
