You may have heard the term “limit switch” for furnaces. It is an important part that affects the safe operation of the furnace. Therefore, if it starts to deteriorate, as all components will eventually happen, it is important to identify the signs and contact the HVAC company immediately.
Know your furnace limit switch
You notice that your furnace shuts down suddenly or runs in a very short period of time. Initially, you might think that this is only related to the temperature of your home or business. For some reason, your stove is adjusted to the thermostat setting faster than usual. But this strange function continues.
what is the reason? Your furnace limit switch may be malfunctioning.
A limit switch (sometimes called a “high limit switch”, more to indicate its function) protects your furnace and your home or business by automatically lowering the furnace temperature when the furnace temperature is too high.
Under normal circumstances, when the limit switch is working normally, your furnace will behave as follows:
- You turn on the heat of the thermostat.
- The furnace burners are activated to begin heating the air in the plenum.
- When the air reaches the proper temperature, the system begins to transport it through the pipe system to the vent.
- When this happens, the limit switch will monitor the temperature in the furnace.
- If the furnace is too hot, the limit switch will turn off the burner and activate the blower to cool the system.
- When the furnace temperature returns to the normal operating range, the limit switch allows the burner to start again.
This cycle repeats throughout the day in cooler months, and limit switches play a key supervisory role.
Furnace limit switch and safe operation of the furnace
Overheating the furnace not only damages the equipment, but also poses a threat to people in the home or business. First of all, there is a risk of fire. However, a damaged furnace may also allow dangerous carbon monoxide to escape.
This is why the furnace limit switch is so important. This is why the furnace starts to shut down unexpectedly when the switch starts to fail. For safety reasons, the heating system is designed so that if there is no limit switch that operates normally, they will not operate.
The sign limit switch is malfunctioning
What are the signs of limit switch failure? In addition to the sudden stop of the furnace or the so-called short cycle, there are two other signs to be aware of. First, if the furnace blower does not seem to be off when it should be off, that is an indicator. Secondly, if the air coming out of the vent is cool rather than warm, this is also a sign.
The good news is that these are indicators that the system works as designed and protects you. However, you need to have HVAC suppliers such as Timberline Mechanical inspect the system as soon as possible. Obviously, in winter, you need a stove that can safely and reliably generate warm air.
Other reasons for electric furnace limit switch tripping
In addition to the failure of the switch itself, there are other reasons why it “trips” or accidentally shuts down the system. For example, limit switches get information from temperature sensors. If the sensor gets dirty (which sometimes happens), it may cause the limit switch to trip.
The switch may also trip due to airflow issues in the furnace. For example, if your stove filter is dirty, it will reduce airflow and cause the switch to trip.
Replacing furnace filters is something you can and should do regularly. The timetable for filter replacement will vary depending on the type of furnace and the filter used. Also depending on the type of stove, you can clean the temperature sensor yourself, but only if an HVAC expert shows you how to clean it.
When to contact an HVAC expert
The ancient wisdom, “Safety is better than regret”, of course applies to general HVAC systems, especially furnaces. In this case, there are multiple aspects to security. First of all, the proper installation of the furnace is essential. If not, the result may be a long list of persistent or recurring problems.
Second, preventive maintenance is very important. Some of these activities, such as regularly replacing furnace filters, are steps you can take to ensure that your furnace continues to operate normally. However, it is also a good idea to get professional services on a regular basis. An HVAC expert can clean and inspect your stove and discover any minor problems with the system in the process, lest they become major problems.
Finally, if you notice that your stove is operating differently for unexplainable reasons—such as a sudden and significant drop in outside temperature, it’s understandable that this will require your stove to cycle more frequently—calling HVAC is very Important experts. First, they can solve any security issues in your system. But there are also cost savings to consider.
For example, it is more cost-effective to replace or repair a faulty system component before it negatively affects other components than it is to perform major repairs on the road. In addition, if your furnace is operating inefficiently, you may have to pay more to keep your home or business at a comfortable temperature.
